The idea of using art to express historical stream routes is a powerful and simple method for connecting people with hidden hydrology.  There are many such precedents, but a recent version I thought I’d mentioned comes from environmental artist Stacy Levy, as part of a workshop at Hunter College sponsored by NYC H20.  I noticed this first on the site untapped cities, and it was covered in the New York Times the following day.

Levy took folks on a tour with some bonus artistic endeavors: “On Friday afternoon, using blue chalk paint, Stacy Levy plans to palpate a few sidewalks on the Upper East Side of Manhattan to visualize the path of a stream, now out of sight, that has been running since ancient times.”   She used the 1865 Viele map of Manhattan, a much documented source of hidden streams in New York, as inspiration of the flows of the walk.  A snip of one of the portions of the map, and a closeup of the 1865 map (which are probably somewhat close in content but somewhat stylistically different).

1874 Viele Map

As the NY Times mentioned, “Searching for the city’s vanished waterways has become a form of specialized detective work, much of which begins with the Viele Map.”   From untapped cities: “Water is one of our favorite substances, yet we know very little about its ways,” says artist Stacy Levy. She explores hidden patterns of hydrology, drainage and microscopic life forms, from tiny microorganisms to large watersheds, using art to reveal the natural processes. This event will explore Levy’s collaborations with urban nature that meld art, engineering and ecology.”

Excerpt of 1865 Viele Map – showing location of tour

There’s also a bit of history from long-time buried creek explorer (both on the surface and as a drainer down in the pipes) Steve Duncan, who has documented this at his expansive Watercourses blog.  He is quoted in the NY Times: “The stream being traced made its way along the east side of Manhattan, with some of it captured in a pond in the southeast corner of Central Park, and other branches eventually flowing into the East River at 47th Street. Historical texts show that a “kissing bridge” crossed it around 50th Street, and the name of the waterway appears to have been De Voor’s Mill Stream”

A great follow-up about the tour was a post “Mystery of the E. 64th Street Puddle” on the ThisEastSide site, which captures a bit of the day of framed in the form of a mysterious perennial puddle.  As mentioned in the article:

“A woman who was walking by, who works on the block, alerted us to the persistent nature of the puddle,” Matt Malina, founder of NYC H2O, told us. “I also overheard a mother say to her daughter as they walked by, ‘That’s why this is the mosquito block!’”

The mystery was solved, again quoting ThisEastSide“The building of Manhattan paved over many primeval brooks and streams.  But some, like the De Voor Mills Stream under 64th Street, just want to be free. The puddle is a spring that feeds the stream. During heavy rains, it fills nearby basements with water.  (A superintendent at one of the nearby buildings told Malina that he keeps a sump pump in the basement for such occasions.)”

Part of Levy’s tour, where “…she recently took a group of volunteers to the site of the puddles (actually, there are two) and supervised their drawing of swirls representing the turbulent water under the sidewalks.”  Seen below, tour goers and passersby joined in the fun, marking swirly water flow patterns on the old path of the buried stream.  In typical urban fashion, the police were called, “concerned that the group was defacing the sidewalk.  Their worries were dispelled upon learning that the medium was chalk.  As it happened, the weekend rains washed away most of the drawings.”  As author Froma Harrop concludes, “So the E. 64th Street puddle is actually a spring feeding the De Voor Mills Stream.  Henceforth, let’s call the puddle a “spring.”  A lot more elegant, don’t you think?”

The chalk paint is an interesting idea to engage without permanently marking – perhaps just to avoid getting the police called on you.  The recent work in chalk is a more ephemeral version of Levy’s 2004 work Streamlines, which used permanent paint, glass beans, stone and bronze to mark 400 feet of waterway along paths at the North Carolina Zoological Park, Greensboro, NC

From her site:

“The hydrological patterns of the nearby stream were enlarged and painted onto the meandering path with road striping paint. Patterns of vortices were painted where the path curved or went past a manhole cover. Parallel lines of laminar flow depicted the straight portions of the path. These amazing patterns are invisible to the eye, but present in all flowing streams.”

From Levy’s website, it looks like there are plenty more inspirations for us to tap into, including one of her projects I’ve used countless times as a precedent for project, the fantastic Ridge and Valley at the Penn State Arboretum, with a stunning etched bluestone plaza with “a 924 sq. ft. map shaped like the Spring Creek watershed” fed by rainwater.

Will spend some more time here, the well is deep.

The first of what I hope are many field trips and investigations is now up on the site in a section called Explorations.  This will be the location for these site-specific journeys, and will be augmented with maps, narratives, soundscapes, and images layered to tell the Water Stories of these hidden streams and buried creeks.

For this initial foray, in Seattle, it was immense fun to wander the areas north of Green Lake and discover the history of Licton Springs. As you see from the map below, the historic routes show a stream flowing southwards into Green Lake.  The reach of the waterway starts around Licton Springs Park, where it is sees daylight for a stretch, along with some other intermittent segments where it pops up in surprising ways, throughout the neighborhood.

The story of Licton Springs focuses on the significance to Native Duwamish peoples, who celebrated the place and it’s spiritual, reddish, iron-oxide infused waters, and to early settlers, who lived and recreated, bathed in thermal pools, and bottled and drank of the healing mineral waters.

Like many places, the history of how the place evolved and how it was maintained is of interest, but the journey of the now and the experience of a day of exploring the edges, the muddy margins, and the sloppy seeps (lost shoes included) connect the history of place to the experience of today.

Beyond the park, there are a number of other discoveries that paint a story of people and place woved together through the flow of water.  Discovery of the story of Pilling’s Pond, a small section carved out of the flow of Licton Springs to provide a sanctuary where Charles Pilling became a world expert duck breeding in the middle of Seattle.

The discoveries also include a unique segment of stream fronting Ashworth Avenue,  a single residential block with driveways and fences literally bridging over the final daylit segment of of Licton Springs, showing how each owner shaped, or left feral, their little piece of the wild.

The connection as well with the virtual, with the final connection is made to Green Lake.  Now only connected via overflow, the tracery of Licton Springs, imagined perhaps in some abstracted water play forms, swales, and cascades, may still be allow the creek to be evident, if only in our imagination.

The link below expands on this summary, so check it out, go out and explore, and come back with some water stories of your own.

Continuing to cover the range of cities with active projects and people investigating hidden hydrology, I return to Indianapolis, which i covered a bit in my early post on Ben H. Winter’s novel Underground Airlines.  The subject of the novel and post focused on Pogue’s Run, a buried creek that served as the locus for a pivotal scene in the novel.  The specifics can also be gleaned from the Atlas Obscura post “You Can Follow a Hidden Stream Beneath Indianapolis—If You Know Where to Look” here for more context on this, which originally was the tip off on this great story.  And definitely, beyond the hidden hydrology reference, the novel was one of the best I read last year.

As with most cities, one river or creek seems to dominate the imagination, and Pogue’s Run is that for Indianapolis, with a number of historical ruminations, such as Historic Indianapolis, which showed a etching by Thomas B. Glessing of “Surveyors mapping the new capital in 1820”, and noting that the stream was probably Pogue’s Run.

In the course of finding out about Pogue’s Run, a number of other interesting people and projects emerged from Indianapolis.  Below are some summaries

Stuart Hyatt

A main feature of the original article, beyond Winters’ book, is the photography and music of Stuart Hyatt, who has documented the underground stream in depth.  A few of his photographs from the previous post, along with links to the video of his band Field Works, whose album is aptly titled ‘Pogue’s Run’.

A video connects the music to place, which “follows a humble waterway through urban neighborhoods in Indianapolis. From its source, through the city, into a mysterious three-mile underground tunnel, and finally to the White River, Pogue’s Run represents the ongoing tension between nature and civilization.”

Charting Pogue’s Run

Artist Sean Derry’s work “Charting Pogue’s Run” investigated the creek via an 1831 map, with a thin line of blue paint and cast iron marks woven through.

A bit of description (longer version on his site):

“Charting Pogue’s Run investigates the past and present characteristics of Pogue’s Run as it flows from the Neareastside neighborhood to its confluence with the White River south of downtown. Beginning on E. New York St., along the boundary of the Cottage Home neighborhood, a blue line and small iron markers map the stream’s 1831 path through the city. This addition to the city-scape traces the streams meandering path across 4.5 miles of Indianapolis.

The work, along with Hyatt’s,  was covered as part of the free workshops, “Rethink, Reconnect, Reclaim”, which “explores creative approaches for improving Indianapolis”.  See a video of the project here:

StreamLines

A surprise was finding the comprehensive Streamlines project, led by environmental artist Mary Miss, a continuation of her legacy of environmental art, in this case “StreamLines is situated on five sites, in diverse communities along tributaries of the White River. Miss’ sculptural elements reveal the natural systems and infrastructure that impact the Indianapolis waterways and encourage exploration of the area.”

Apart from site specific art: “StreamLines is an interactive, place-based project that merges the sciences and the arts to advance the community’s understanding and appreciation of Indianapolis’ waterways. This work is made possible by a grant from the National Science Foundation and is modeled on the City as Living Laboratory/FRAMEWORK.  StreamLines features art created for specific sites along six Indianapolis waterways of focus to Reconnecting to Our Waterways (ROW): Five environmental installations by Mary Miss/City as Living Laboratory® (MM/CaLL); A series of dance performances by Butler University Department of Dance; Six musical compositions curated by Michael Kaufmann/The Kinetic Project; A collection of poems penned by Indiana poets selected by Poets House”. 

A diagram of the concept of her site specific installations, which include similar themes, as noted, around the concept that ‘Rivers are the Lifelines of our Cities.”

Along with some of the installations themselves, which are place based but tied together thematically.  An excerpt from her site “At each site, the three states of water – ICE, VAPOR, WATER are written on the surface of the mirrors. Words on the ground express the themes of each different location. They are formed of reverse letters, which are legible in the reflection in the mirror above.  Site themes address water and its many states in the environment, the importance of water to Indianapolis’ development and history, water infrastructure and the connection to the watershed.  At the outer edges of the installations, smaller mirrors (18” in diameter) and small pedestals in groups of two or three present texts, much of it legible only in reflection, such as poetry, scientific and historical facts, riddles, jokes, prompts, and questions. These texts also direct visitors to the app and website for additional information.”

The markers and poetry are located in and around installations, circling back to the formative river, the poem “Pogue’s Lost Horse” by Catherine Bowman connect to the place in other ways, through words, visions, and rhythm.

The dance and musical numbers are available on the site and best captured in video, as well as the Streamlines Vimeo page, which also has interviews and other info.  One of my favorite is the ‘Choreographing the Movement of the Waterways’, described here: “This video explores the story behind the dance component of StreamLines. On September 24, 2015, more than 100 members of the Butler Ballet performed Riverrun, a site-specific dance choreographed by Butler University Dance Professor Cynthia Pratt for the StreamLines project. This dance was part of the programming for the project’s launch and performed in Holcomb Gardens on the campus of Butler University. The site-specific art invites the community to learn, explore and experience the science of Indianapolis’ water systems”

There’s also a video delving into the work on the musical composition and soundscape, and “explores the story behind the six musical compositions of StreamLines. Curator Michael Kaufmann worked with six musical artists – Olga Bell, Hanna Benn, Stuart Hyatt, Roberto Lange, Matthew Skjonsberg and Moses Sumney – to create the sound art for StreamLines. The site-specific art invites the community to learn, explore and experience the science of Indianapolis’ water systems”

Beyond Pogue’s Run, the work draws from a variety of local waterways, as mentioned in this post from Next City“The White River flows through downtown, joined by Fall Creek, Pogue’s Run, Central Canal, Pleasant Run and Eagle Creek, many of which also flow through Indy’s most underserved neighborhoods.”  Part static placemaking and part events, there is a simple google map to locate the places included.

It’s really interesting to see how Indianapolis expresses the connection to lost waterways and hidden hydrology primarily through art, spanning literature, dance, poetry, music, and environmental installations.  It showcases the diversity of means to tell these water stories – technical, mapping, ecological, historical, artistic, designer, and provides a unique snapshot of a community, it’s rivers, and how each are shaped, and shape one another.

 

Week three of the Waterlines class featured Seattle writer and geologist David B. Williams.  Perhaps best known as the author of the recent ‘Too High and Too Steep’, a chronicle the large-scale manipulations (topographic and hydrologic, to name a few), Williams shared a more focused talk on his upcoming book Waterway: The Story of Seattle’s Locks and Ship Canal, which coincides with the Centennial of the Hiram M. Chittenden Locks this year.  Following the course theme, and touching on some previous topics, the story encompasses the trials and tribulations to get the locks built, and the large-scale impacts that such endeavors have on the ecological and hydrological systems of Seattle.

David is an engaging storyteller, so he laid out the evolution of this significant part of Seattle’s history, touching on the geology (with the north south orientation how important the waterways were to getting around, especially, east-west movement), and the use for years by native people, who used the portage between Lake Washington to Lake Union, and then a quick connection to gain access to the ocean, and vice-versa, for the past 10,000 to 12,000 years, with stories of Kitsap Suquamish coming to Lake Washington because it was one of the largest freshwater lakes in the region.  The idea of a ship canal of some sort is as old as Seattle itself, first pitched by Thomas Mercer in 1854 and finally coming to fruition as a way to move coal, timber, and people, after many attempts 63 years later.  In fact there were multiple routes proposed and attempted with big Seattle names like the aforementioned Mercer, along with Burke, Denny, and Gilman, cutting through Smith Cove, routes across what is currently downtown, and one of the most absurd in Seattle’s history – the Semple Canal.  This map shows a number of these routes, and also the one natural, yet not very viable connection vai the Black River, which was mentioned in the previous post on Seattle archaeology as outlet from Lake Washington and would eventually fall victim to the draining of Lake Washington.

As mentioned, Semple’s Canal was perhaps the craziest scheme, wanting to slice through one of Seattle’s seven hills, Beacon Hill, which stands almost 350 feet tall.  Williams documents it on his blog in this post, with a couple of graphics showing the route and section cut (noting a maximum cut of a mere 284′-6″), highlighting the absurd notion of cutting a canal through a hill, although a good portion of the material removed from the canal before it was shut down was used to fill the Duwamish estuary into what is now industrial lands, and frankly, based on some of the other history, it would not have surprised me if this would have happened.

The eventual route of the Canal was landed on eventually towards the end of the 19th century, connecting to the Puget Sound through the existing Shilshole Bay and the eventual location of the locks, connecting through Salmon Bay, which was a fluctuating saltwater tide zone, connecting through the Fremont Cut to Lake Union, and the Montlake Cut connecting Portage Bay on the west with Union Bay and larger Lake Washington on the east.

The conditions prior to implementation show Salmon Bay connected to salt water, and involved slicing through Ross Creek and wetland zones between Salmon Bay and Lake Union, where a creek was feeding the Bay.  To the east the portage had become a narrow log flume at the narrowest point connecting Union Bay and Portage bay, completing the connection from lake to sea.

As mentioned, the eastern Montlake Cut was used as a log flume with a narrow channel (developed by Denny and others) connecting through Portage Bay, and a similar effort was made to connect through Ross Creek via what is now the the Fremont Cut.  A photo showing the area looking from Union Bay towards the west from Paul Dorpat’s blog showing the isthmus with Portage Bay in the distance prior to ship canal.  This area was sliced through with a log flume (seen on the 1894 map above) in the 1880s and at times through the early 1900s to move timber from inner areas to Seattle and beyond, setting the stage for the eventual connection.

A second image showing the narrow connection of the log sluice from 1886 that is seen on the 1894 map, one of the thin connections which eventually were expanded for free flow of goods and people across Seattle.  A dam at the upper end held Lake Washington above the level of Lake Union, and logs were dropped into this chute to float on the next leg of the journey.

While the connections seem logical, the elevations of each water body were different, with the level of Lake Union around +20, the level of Lake Washington at +29, and Salmon Bay elevation lower as it entered the Puget Sound, often not having standing water at times.  The process of building the locks set all of these elevations at the same as Lake Union, which raised Salmon Bay and made it a continuous fresh water bay, which is why it works as a place to over-winter fishing fleets as it is today (see Deadliest Catch) to keep boats out of salt water.  It also lowered Lake Washington, which as mentioned disconnected the lake from it’s natural outfall at the Black River to the south, replumbing the south area of Seattle while creating a whole lot of new lakefront land.  The completion of construction of the locks and the eventually breaching of the Montlake coffer dam (below) and the other coffer dams at the Fremont Cut, (after having to shore them up a few times), filled Salmon Bay with fresh water, and caused Lake Washington to drain down the 9 feet slowly over a few months

The locks, which opened to fanfare and massive 4th of July celebration in 1917, are fun to visit today to watch ships come in, go to the fish ladder, and see the activities.  According to Williams, these are the only government locks in the US that are crossable to the public (didn’t know that) and the main traffic, although peppered with an occasional working vessel to Portage bay, consists mostly of pleasure craft.  Also, while they did originally build a fish ladder, it didn’t work well (and was improved years later, which make a fun viewing opportunity).  Williams mentioned that fish tended to just get into the locks and ride up to travel upstream.  It’s an interesting resilience story that fish that were cut off from the Cedar River where they spawned when the Black River was disconnected, and instead of heading up the Duwamish/Black/Cedar to the south, would still be able to figure out how to get upstream via alternative routes via Shilshole miles north from their original spawning route. Talk about a well established navigation system.

The impacts for Seattle, much like the other massive changes, ended up having huge economic implications in positive ways, with the ability to tap into industrial lands for coal, timber, and shipbuilding, and some minor military use, along with what are mostly now marinas for pleasure craft today.  The fact that maritime industries are only second to aerospace in the Seattle economy is surprising, which owes much to the ship canal.  Seems a common story for Seattle, make massive change and reap the benefits (to some), even if it cuts off a river that happens to be the home place for local Native people.  To comprehend the 60+ year journey from idea to fruition, and the hundred years of operation since, another story of changing land and waters influencing our urban lives every day. Excited to see some of the events and read David’s upcoming book for more.  On that note…

Addenda: Making the Cut

A great resource on the upcoming centennial festivities is the website Making the Cut: The Locks, The Lakes and a Century of Change, which provides info on events, much of the history mentioned above, and a good section on historic maps which shows a good cross section of hidden hydrology in relationship to the hydrological manipulations to connect the lakes to the ocean.  A series of before and after maps documents the changes in the locks, Lake Union and Lake Washington, and other areas.  The series below highlights the evolution from the tidal marsh of Salmon Bay prior to the locks being installed in 1916 to the freshwater waterway today.

Salmon Bay – Today
Salmon Bay – prior to 1916 | Blue = Water |  Green = freshwater wetlands | Pink: saltwater wetlands | Brown: intertidal areas (or tidal flats)

Last week was Part 2 of the Waterlines class, featuring archaeologist Dennis Lewarch, Suquamish Tribal Historic Preservation Officer, with a concept of ‘Before the Cut’.  This was an exploration “using archaeological, ethnographic and historical data [to discuss] the effects of shoreline transformations on indigenous populations.”  Similar to the first class, the depth and breadth of the cultural history, and his more expansive title ‘Archaeology and Ethnographic Background of Seattle and Prior Massive Anthropogenic Modifications” hints at the depth of this topic.

Lots of details here, but the idea that in the past 14,000 years of occupation by native peoples, after migration from the north via the Bering Land Bridge and along the outside edge of the ice.  There are various theories, but that the retreating glaciers opened up a path between that allowed access, and continuous occupation is found throughout the Northwest in archaeological sites 12-13000 years of age. Once here, the land has changed via sea level rise, mudflows, earthquakes, tsunamis, subsidence, alluvial processes, and more.  The story is thus the land shaping people, and the people shaping land.  The defining characteristics of the different tribal groups are called adaptions, and place origins of geography, such as the Saltwater adaptation, particularly the Suquamish who lived near the sea, versus the Riverine adaptation, the Duwamish people who lived near the river.  Other adaptations are tied to lakes and inland/upland areas, all of which collectively shape the speech, family community, and cultures.  For Lewarch’s presentation, the focus discussed a larger history of regional indigenous occupation of the Seattle area, with focus on some of the areas near Seattle that had significance.

Black River Origins

One of the main points of origin for Duwamish people, based on the above adaption, is the Black River, where four original villages were located.  An excerpt from the 1909 USGS Topographic map of the area shows the former drainage, where the Cedar River flowed in from the east, and the Black River drained the south part of Lake Washington, near Renton.  This confluence also was fed from the south by the former route of the White River, as all of it flowed into the Duwamish and out to the Sound.  The names of the settlements of the ‘People of the Lake Fork’ and the inhabitants near the Little Cedar River, and their evolution in living off the land and the river ecosystems for many years.

The demise of this home place began with channelization of the Cedar River into Lake Washington, and ended he lowering of the lake when the Hiram M. Chittenden Locks were built in 1916.  The elevation of Lake Washington was lowered nine feet, to the same as Lake Union, which severed its outflow to the Black River, captured in the photo below shows the river after the lowering of the lake, where it slowly died and has (mostly) been subsequently buried.  For more on the Black River history, a short blurb on this from David Williams here. 

 

The map from the Wikipedia page on the Black River also shows the before and after and the erasure of the original location of Duwamish settlements through reconfiguration of the hydrology of the region, another in a long line of massive manipulations in the region.  The Duwamish People were living in the area, and continued to do so, even as the Black River was dying.  They were relocated to reservations, and as Lewarch mentioned, they were sent to coastal areas near the ocean, and being a river tribe, kept returning to the river to fish for many years after, where they lived on a property owned by Erasmus Smithers, until it was burned in 1896.  There’s inevitably a long history of settlement and resettlement and disenfranchisement throughout recent history I’m glossing over, but the idea of a river tribe not having a river seems par for the course of how tribes were treated.  Secondary to this, the subtle differences between different tribes were not recognized, with many Suquamish or other tribes in the region being lumped into the Duwamish by colonists.

Duwamish River

The Duwamish River obviously had a significant place in the history of this river tribe, and the estuary connected the river people with those of the sea and the density of place names in that zone .  A number of archaeological sites amidst the oxbows of this area.  The 1899 US Coast Survey shows the bay and larger estuary, with the area of downtown Seattle starting to build out, but prior to the majority of the land filling to come.

A map of these old configuration juxtaposed with the channel that exists today shows the level of land filling and manipulation done to this area to carve out industrial lands.  From the fantastic Duwamish Revealed site: “About 100 years ago, the Duwamish was straightened and dredged, reducing 14 miles of winding river to 5 miles of industrial “waterway.” Nearly all of the native habitat – mudflats, marshes, and swamps surrounded by old growth Cedar, Douglas Fir, and Hemlock trees – was replaced by agriculture, then industry.  The Duwamish is home to three Native tribes: The Duwamish, the Muckleshoot, and the Suquamish, and has immense cultural importance to them. The word “Duwamish” is an Anglicized version of Dkhw’Duw’Absh, meaning “people of the inside” in Lushootseed, the language of the Coast Salish people.”

Ballast Island

While native peoples were instrumental in building the city and working in it’s saw mills, fisheries and other industry, rapidly changing Seattle began to try to eliminate the native residents of the city, passing laws in 1863 to make it illegal for Indians to live in Seattle unless they worked for whites, villages and settlements were burned.  Native peoples moved north as development occurred, and tended to stay near the water, occupying places within the network of piers and wharves.  One such place was Ballast Island, formed from ships dumping rocks after their voyages, which slowly accumulated into made land.   A photo from the area shows the colonization of this space by Native peoples, who camped out around the wharfs fringes, being ogled by early Seattlites.  In 1891 they were forcibly removed, one in a string of forced removals that shaped the early history of the area.

West Point & Shilshole

Moving away from downtown, the occupation and history of West Point, the point that was formerly military outpost and now Discovery Park, along with being the massive sewage-treatment plant.  This area was a tidal marsh that was occupied and used, with the formation of sediment along with earthquakes shaping.  When the treatment plant was being expanded, a significant archaeological effort was undertaken, beautifully documented in this online resource from the Burke MuseumShilshole also has a significance to Native Seattle, with the native word meaning ‘threading the needle’ to get into the small mouth that led into Salmon Bay, which was littered with shell middens and other features showing occupation, similar to other areas on the coast.  Prior to the creation of the locks, this area .  One long-time resident was Salmon Bay Charlie.  A great resource for this and other Seattle history is the blog by Paul Dorpat featuring ‘Seattle: Now & Then‘, where you can investigate the area in some more detail.  From the post: “Salmon Bay Charlie and his wife lived in their cedar plank home on the south shore of Magnolia’s Salmon Bay. For half a century Charlie, also known as Siwash Charlie, sold salmon, clams and berries to the first settlers and later to the soldiers at Fort Lawton.  Today’s historical view shows Charlie’s house at the turn of the century, taken by the photography firm, Webster and Stevens.”

A bit to the east, the connection between the eastern edge of Lake Union and Lake Washington is a good discussion of place names, including the connections between Lushootseed, or Coast Salish names and colonist names. This brought up a discussion of the area below,

I rotated the Waterlines map to match the same orientation, and the references to the area marked B, which was a village site named sɬuwiɬ, “Little Canoe Channel” that marked the mouth of Ravenna Creek, where Lewarch mentions there were stories of salmon runs up Ravenna.  There’s also Lake Union, marked as #21, which is called x̌ax̌əču meaning, “Small Lake” and Foster Island, in an area named staɬaɬ or “Baby Fathom” showing that even with a translation there is still a story missing.  Perhaps a shallow zones at the mouth of the creek.  The cut, marked as #18 which is named  sxʷac̓adwiɬ translated as “Carry a Canoe” meaning it probably wasn’t passable as a waterway until later when the Denny’s opened it up as a log-sluice to move timber between the two points.

The conversation of ethnography and language started with T.T. Waterman, who studied local tribal place names in the 1920s, seen in publications like “The Geographical Names Used by the Indians of the Pacific Coast” and the author of the book Puget Sound Geography, which was edited by Vi Hilbert, Jay Miller, and Zalmai Zahir.

According to Lewarch, the notes from Waterman were sort of a mess, so the editors compiled it into something readable, including an amazing figure in Seattle history, Vi Hilbert, a Puget Salish and “a conservationist of the Lushootseed language and Culture”.  While Waterman interviewed a small group of around 25 native people for his work, it generated over one thousand place names.  And as Lewarch mentioned, all of those interviewed said if they had talked to the Elders, they would have ended up with 1000s more, a sad testament to a cultural history lost forever.  Another resource for this is Coll Thrush’s book ‘Native Seattle‘ offers a great section with maps of those place names developed along with Anthropologist Nile Thompson, a snapshot of one below with the accompanying Lushootseed language and origins.  Many of these as I mentioned ended up on the Waterlines map, with more abbreviated descriptions.  The one below shows the NW corner with Green Lake in the center, and West Point, Lake Union, and Salmon Bay, along with areas along the coast marked.

CONCLUSION:

Lots of threads to follow and stories to connect.  In general, the talk focused on the Indigenous cultures and their resilience, both pre-European settlement and after colonization, displacement, and more.  He ended up with a quote from Chief Seattle, and discussion both of the potential misinterpretation of his words by the translator, and whether it was an environmental, or social statement, but the multiple meanings that resonated strongly in Seattle history.   He quoted a passage:

“And when the last Red Man shall have perished, and the memory of my tribe shall have become a myth among the White Men, these shores will swarm with the invisible dead of my tribe, and when your children’s children think themselves alone in the field, the store, the shop, upon the highway, or in the silence of the pathless woods, they will not be alone. In all the earth there is no place dedicated to solitude. At night when the streets of your cities and villages are silent and you think them deserted, they will throng with the returning hosts that once filled them and still love this beautiful land. The White Man will never be alone.”

Chief Seattle’s niece at her Shilshole home, 1901 – via http://www.duwamishtribe.org/culture.html

It could be both a warning or a statement that shows that resilience of Native people wasn’t just in survival, but left a permanent mark on the landscape and people.  The culture and place of what Seattle is and the way we should live is etched in history and resonates in the places dotting the map of Seattle, including waters visible and hidden.

ADDENDA:

A preliminary presentation featured Amir Sheikh, one of the primary collaborators on the Waterlines Project, and he discussed much of the history and process of the overall project and methodology along with framing the concept of place names using Lushootseed language, as featured on the Waterline maps (see my post on language here).  One video he showed was “Djidjila’letch to Pioneer Square: From Native village to Seattle metropolis“, a video which takes the viewer “…from Native village to metropolis, the Pioneer Square neighborhood of Seattle has undergone dramatic transformations. This animation provides a bird’s eye glimpse at some of the social, economic, and landscape histories of the neighborhood through time.”

If you haven’t had a chance to check out the installation ‘Calling Thunder: Unsung NYC’ it’s a fantastic example of using digital storytelling methods that connect with hidden hydrology.  The project extends the work of the Welikia Project. which provides ecological history of New York along with some great visualizations of pre-development in the form of maps and 3D graphics.   A little background comes from the article in the NY Times from April 25th, ‘The Sounds of ‘Mannahatta’ in Your Ear’:

““Calling Thunder,” is an aural bridge across four centuries. It builds on Dr. Sanderson’s stunning work, with Markley Boyer, in creating visualizations of the rolling landscape of 1609 Manhattan — known by the Lenape people as Mannahatta, “the island of many hills” — that are twinned with photographs of the same points in the modern city. We see hills and streams at places now occupied by skyscrapers and subway tunnels; a red maple swamp where an H&M store stands in Times Square.

Drawing on the work on Mannahatta, the immersive video and 360 video and soon VR animate the lovely maps that populated the original books.  As one moves through the pre-1600s aerial imagery, it transitions to the modern cityscape,  The visuals showcase the heart of the book “…published in 2009, and its classic, bookly virtues — visual beauty, wit and imagination, all underwritten by deep scholarship — persuasively deliver its most astounding revelation: Manhattan in the 17th century had more ecological communities per acre than Yellowstone, more than most rain forests or coral reefs.”

The soundscapes are the best part, a collaboration between “… Bill McQuay, a former sound engineer with NPR who is now an audio producer with the Cornell Lab of Ornithology, and David Al-Ibrahim, an interactive storyteller and graduate student at the School of Visual Arts.”   Using sounds from the Macaulay Library at Cornell, the soundscapes piece together species, for instance, in recreating the Collect Pond, the species of American Crow, Marsh Meadow Katydid, Bullfrog, American Bittern, Baltimore Oriole, and Black-capped Chickadee are culled from the site specific ecologies of Welikia and the range of possible species present, which is a fascinating way to experience the site.  A snapshot of the area near the Collect Pond Park shows a wide range of species to drawn sounds from,

 

I was a bit disappointed with the visuals that accompanied the soundscapes, simple, abstract, placeless sketches that distracted, more than accentuated the experience.  Looking around, one wished the simple site-specific scenes were rendered in the same graphic style as the larger renderings, only more animated scenes with residual movement, wind, rustling leaves, and environmental cues that evoke the historical places, perhaps transitioning between new and old.

Maybe a fitting next stage for the project, a simple immersive VR experience could be done without a lot of work, but the sketches aren’t going to cut it.  The goal of capturing a vision of what was and what is, with a measure of interactivity that heightened awareness of the habitat sounds would be attainable, as seen through the myriad .  I found that closing your eyes and immersing in the sounds was the best way to experience this.  The dilemma is hinted at in the article: “At first, Mr. Al-Ibrahim said, he considered presenting only the sound from each of the sites. “It turns out people don’t respond well when put in pitch blackness with a headset on,” he said. By offering readers and listeners the choice of technologies, the project sidesteps the trap of endorsing one storytelling technique to the detriment of the actual message.”


The method of disseminating historical ecology, and pair the experience with soundscapes showcases.  As a quote from Sanderson mentions, which is clear from the work on Welikia and Mannahatta, the abundance of species. For a city known as one of the most dense and urban, the previous natural resource is somewhat surprising.  This is the beauty of connecting the past and the present.

As mentioned, “The Unsung website offers various ways to take in the weave of history, research and informed speculation in “Calling Thunder,” each with its own rewards: as a simple audio recording, 360-degree video, or, coming soon, virtual reality.”  I can’t wait to see the next installment and appreciate the inspiration of full-sensory experiences.

A great kickoff lecture to the Waterlines class at the Burke Museum featured noted regional geologist and retired UW Professor Dr. Stan Chernicoff and his exploration of The Origins of Seattle’s Landscape.  Having read a bit about the local geology over the years, and having experienced some specifics (particularly the glacial till in Seattle) in my work, I had a rudimentary understanding of the general picture in our region.  Thanks to this lecture, and the philosophy that ‘dynamism is key and change is inevitable’ espoused by Chernicoff, I know a lot more and think about the region in new ways.  From his lecture, I found some interesting links between the larger and longer scales of geologic time and it’s relevance to the Hidden Hydrology project.

His lecture loosely focused around the concept of changing Waterlines around the region, and organized his talk to be roughly chronological and covered a lot of ground – from 1.1 billion years into the past to 250 million years into the future.  Much of the beginning conversation was looking back at the time when Seattle was not coastal but inland as part of the Rodinian Supercontinent (one of the pre-Pangean configurations) and the coastal accretion of lands from the final supercontinent (where to coast was originally at the MT/ID border), and the lands that were added over the past 150 million years (Okanogan Mountains, Cascade Mountains, San Juan Mountains and most recently the Olympia Mountains) through lands being drawn in through subduction.  This means that Washington and Oregon are mere infants in the larger timescale, as Chernicoff mentions, compared with the larger geological history.  The key diagram he showed here is the overlapping sections of the subduction zone in the Juan de Fuca plate and the location of between the Olympics and the Cascade Mountains, with the layers levels and timelines of geological traces over the past 50 million years..

The bit of trivia that Seattle is sitting atop the Olympic Mountains – as you can see by drawing a line through to the Crescent Basalts below us.  The evolution from the last 40 million years in shaping the zone, through Volcanic mudflows (yeah, there was a volcano called Mt. Seattle somewhere near Issaquah) that left lahars 40 million years ago.  This was followed by periods of inundation, and when the land was warm and swampy, which left the deposits of coal near Renton (an interesting Puget Sounds coal history where we ended up shipping to San Francisco).  The marine heritage is also found in the prevalent Blakeley formation, which evolved from a shallow marine estuary from submarine landscape deposits 30 million years ago – and today one can still find fossil shells around many places in the Puget Sound.

There are some interesting facts that illuminate this history and dynamic story of change.  First, while the larger geology set the stage and influences the form, the current lakes, and rivers were a product of the latest glacial period, which Cordilleran Ice Sheet covered the area and the Puget Lobe formed the shape of the current region.  The glacier was around 3000 feet thick, which pushed the sound down almost 1000 feet, and created the depression that allowed water to flow in and formed the modern position of waters.

The rule of thumb is the thickness of depression will be 1/3 the thickness of the glacier.  An interesting section (see right) showing how this cap of ice carved out Puget Sound nestled between the Olympic and Cascade Ranges –  with linear scoured channels forming Hood Canal, Puget Sound, Lake Washington, Lake Sammamish, and created the terrains which Seattle occupied.  These were all relatively north-south oriented which coincides with the intrusion and recession of the Puget Lobe.  It is amazing to think of the larger glaciers in the Midwest, such as Minnesota, which were 3 miles thick and the impacts on that landscape, which for my knowledge, creates the rarity of the north-flowing Red River through where I went to college in Fargo, but also created the over 10,000 lakes that dot the region.

Second, is that because of the glaciation and recession, most of the hills in Seattle are glacial drumlins, (with the exception of West Seattle and Magnolia which are drift uplands).  These hills were deposited upon glacial retreat, which gives them a distinctive steep north side and smoother south side, with alignment north-south as well as the long side corresponds to the direction of ice flow.

You see this in the larger hills in Seattle, as well as the creation of the individual creeks that are woven throughout the north section of the city. The topography carved these smaller drumlin shapes with drainages forming in the spaces at edges adjacent to lakes or between two hills. This formed unique geologic features like like Seward Park in the south section of Lake Washington.

A shapshot of the 1894 USGS Topo map shows the formation on Queen Anne (left) and Capitol Hill (right) with the steeper north edges, along with what is still showing the remnants of Denny Hill south before it and other topographic features were removed from the downtown area.

Third, the two smaller lakes in North Seattle, Bitter Lake and Haller Lake, are true kettle lakes, formed with glacial retreat.  A hybrid of this is Green Lake, which also formed in the glacial retreat along with Lake Union and Lake Washington. Fourth, the glacial movement left a trail of glacial erratics all over the area, and I learned about one of the largest, the Wedgwood Rock, which originally was from miles north and now sits in NE Seattle.  Definitely worth a field trip in the near future.

Fifth, the glacial deposition led to a preponderance of landslides, both with steep slopes, along with the layers of permeable Esperance Sand sitting atop a layer of Lawton Clay, which causes water to flow under the sand and create a slip zone (shown on right side of diagram below).

This is exacerbated by the copious winter rainfalls, which exacerbates the issue via critical liquifaction zones, which  means “…a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid.”  Thus the landslides and earthquakes have shaped the hydrology over time, as valley configurations shift with deposition from streams but also are influenced by these disturbance regimes.

The Magnolia Neighborhood is one of those areas where it has overlapped with the danger of building on steep/unstable slopes, as shown here in a wikipedia image of a slide in 1954 on Perkins Lane, a relatively frequent occurrence in Seattle in particular areas over the years.  Chernicoff’s hint:  Don’t by a house there.

The final part of Chernicoff’s talk focused on the ‘Rise and Fall of Seattle’, with a theme that in our dynamic and ever-changing landscape, “we can’t get accustomed to where water is”.   He mentions four factors that will influence the geology of Seattle, including Local Geology, Regional Tectonic Factors, Regional Isostatic Factors (i.e. glacial rebound), and Global Eustatic factors (i.e. sea level rise).  This was interesting, as the local conditions were all creating conditions that led to raising lands and lower levels of water.  For instance, the two local geological factors were river sedimentation and landslides, both of which add land particularly at the deltas of larger rivers, such as the Skagit and Nisqually Rivers.  As Chernicoff put it, through those two factors, the entire Puget Sound is trying to fill itself in.  The regional factors of tectonic activity are at work, with quakes occurring regularly, which can instantly change the shape of our landscape through an earthquake.  A slower mechanism continues to shift land with raising land due to glacial rebound, bouncing slowly back from being compressed by glaciers thousands of years back.

Inevitably, for all the minor modifications of local and regional factors, the larger impact is, wait for it… yep, global change, in particular the shifts associated with climate change.  The melting of remnant ice sheets in Greenland and Antarctica, warming causing the thermal expansion of water combined to create higher levels, and lead to massive impacts on the waterlines of Seattle and everywhere else.  He showed as an example a slide of the map Islands of Seattle, a great project by Jeffrey Lin (inspired by the original Burrito Justice San Francisco Archipelago map.) which hypothesized on melting of all global ice, including the Antarctic, which would result in a 240′ rise in sea level, creating a very dramatic new waterline and hydrology for the City.

For Chernicoff, it wasn’t a question of whether this would this happen or not.  His geologists time lens is long and he knows there will be large-scale global shifts.  The question is yes, however, does the time scale of this inundation take 30 years, 500 years, 10000?  It’s an interesting juxtaposition of of deep, long geological time coupled with the dangerous (but possibly earth saving) agency of humans in creating changes in rapidly shorter and shorter time scales, via anthropocentric factors.  While we rightly fret over our fate and try to come up with solutions, the idea of dynamism and constant change is a good perspective. In the end, geological time and processes will, it seems, always win, if we’re around in another 250 million years we can experience a new shift to a larger subcontinent, as the Pacific is getting smaller and the Atlantic is getting bigger, so our coastal woes will change when we’re in the middle again.  Full circle.

This has some implications, obviously for connecting history to present and future, as we are constantly chasing moving targets when we deal with landscape and water.  How will these changes impact our understanding of historical conditions with current ones?  At the short time scale we are considering, does it matter?  Will rapid global and local changes impact our opportunities and ideas in which to engage with planning and design interventions?  Something I’ve not ruminated on long enough to have ideas, but more to come.  And more on Waterlines next week.

A short rumination from Akiko Busch in the NY Times asks us to Learn a River’s Name Before It’s Gone resonated with me around the idea of language as the cultural thread that weaves.  Describing a road trip, where she wrote down the list of over 100 rivers crossed, concluding that “If we couldn’t hear the sound of the water itself, the syllables of the names became a new way for me to chart this country.”  The simple idea of knowing the name of something (or someone, for that matter) and although we go a bit crazy with naming storms, Busch posits that:

“it would likely be of greater benefit if we could find a similar pleasure in learning a few of the names that identify those features of the natural world we live with all the time. Which is to say, instead of making up new names, we might consider learning the names that already exist.”

Data and science are critical elements in understanding on many levels, but words and names provide a level of connection.  Busch continues: “Giving something a name is the first step in taking care of it. Place names help us to attach landscape to history and region. And when it comes to the question of attachment, we are not just speaking of how names are attached to places, but how humans become attached to places.”  Stories of places abound, and continued attacks on environmental regulations aims to further degrade our protections, so “perhaps we could make the effort to learn as many of the names of those places — and the trees, the rivers, the ranges, all the species that live there — as possible, before it’s too late.”

Robert Macfarlane, quoted in Busch’s essay above, says that “Once a landscape goes undescribed and therefore unregarded, it becomes more vulnerable to unwise use or improper action.”  To me he embodies the idea of naming and knowing, and I was fascinated by his take on the vibrancy of language, and the stories of how this language is being lost, and the need to retain it – from this Guardian article ‘The word-hoard: Robert Macfarlane on rewilding our language of landscape‘.  I wrote about this here in Landscape+Urbanism, and have been currently reading his book Landmarks, which breaks down place language in short essays interspersed with lists focusing on language specific landscape features.  The resources   The publication of his book led to him receiving a deluge of words from readers from around the globe,  Recently on Twitter, Macfarlane posts daily words and continues to collect new ones and has amassed a following of those interested in the word hoard.

This idea connects with other writers of lexicography, such as the fabulous book Home Ground: A Guide to the American Landscape, edited by Barry Lopez and Debra Gwartney, which provides  “descriptive language for the American landscape by combining geography, literature, and folklore” and those gems that have been formative for many landscape architects, such as Anne Whiston Spirn’s poetic Language of Landscape.  New forms are emerging as well, such as the Lexicon for an Anthropocene Yet Seen,   Many

Whose Language, Whose Culture?

The naming, of course, needs to respond to pre-European settlement, as much of the work of ‘finding’ hidden hydrology uses maps that are made by Europeans and often (purposely or ignorantly) erase place names that have be tied to places for years.  As we look back into history, we are challenged to find not just the names of places on a map, but to search a richer heritage of Native place names. The work on the Welikia Project explains: “The Lenape people inhabited Mannahatta for thousands of years before the Europeans arrived. They named their island home “Mannahatta,” meaning “Island of Many Hills.” We use the term “Mannahatta” to refer to the island as it was in 1609, and “Manhattan” to refer to the metropolis of today.”  When they expanded the concept to the larger NY City metro area, they also adopted the Lenape expression “Welikia,”meaning “my good home,” and infuse place making with Native settlement patterns often in their work.

The Waterlines Project here in Seattle is a great example of connecting Hidden Hydrology to Native language, providing on the map a key with Coast Salish Place Names.

The place names on this map, written in the Lushootseed language of the Coast Salish people, are drawn from elders who worked with ethnographers in the early twentieth century, from the work of linguists and scholars such as the late Vi Hilbert, and from an atlas created by Coll Thrush and Nile Thompson for the book Native Seattle.  Place names are stories: proof of presence, archives of meaning, evidence of ancestry, and a reference for treaties and other legal connections to territory. They provide context to the ongoing presence and strong connections to the city for Native people as co-managers of our shared resources. Refer to “An Atlas of Indigenous Seattle” for further information on the Native place names found on this map.”

I’m inspired to learn the names (those of the present, past and distant past) of the local places across history and dig into some of these local resources as I continue to compile my working base of Seattle and Portland Hidden Hydrology.  I found a post by local writer David B. Williams on his GeologyWriter blog – which was helpful in summarizing Seattle’s Stream Names, for the more recently naming, and soon to come is some documentation of my recent muddy exploration of Licton Springs, which is named for Liq’tid (LEEK-teed) or Licton (Item #9 above), the Lushootseed word ‘Red Paint’ for the reddish mud of the springs.

Reclaiming the Duwamish
Eric Wagner and Tom Reese
Eric Wagner and Tom Reese, author and photographer of Once and Future River: Reclaiming the Duwamish, discuss the history of Seattle’s relationship with its one and only river. Wagner’s writing has appeared in Scientific American, Smithsonian, Audubon and other publications. Reese is a Pulitzer Prize-nominated photojournalist recognized for his feature work and explanatory reporting during his career at The Seattle Times.

A gem of a publication semi-related to hidden hydrology by very related to cool maps, is one the US Geological Survey Miscellaneous Investigations Series I-1799, published in 1988, entitled the “Atlas of Oblique Maps: A collection of landform portrayals of selected areas of the world“.  As noted, the maps are all oblique aerials, and range from 1961 to 1986, so are pre-digital.  The ability to represent complex geographic and topography features enlightens many maps of this sort, and the techniques to create this makes for a fascinating read.

Some introductory text from the Preface:

There’s a brief by interesting background for the document and some of the key map-makers, including A.K Lobeck, E.J. Raisz, and P.B. King.  Some of the benefits of this type of map are discussed, including more realism and easier comprehension, and ability maintain scale.  Disadvantages included displacement of features, and hiding of key elements, and a relative inexactness of elevation and location.  I think of many of the maps of cities in the late 1800s that were drawn using similar techniques, which show features in a compelling way, but somehow exist with a tantalizing lack of precision.

The graphic standards used are explained, which allows for some uniformity. (click to enlarge):

The mechanism of the Isometrograph was fascinating, which provides the opportunity to “develop a parallel-perspective framework from a vertically viewed contour map” allowing for three-dimensionality without reproducing hidden lines, something we can easily do today with a number of digital tools, but at the time was pretty incredible.

That said, there’s a ton of interpretation and creativity involved, to take the three-dimensional framework and convert it into a compelling illustration, as noted in the sequence below.

So why should these matter, aside from their value as historical maps. The conclusion sums it up, along with a very prescient commentary on the value and future of mapping in our current age of Google Earth:

“Because oblique maps are instructive and easy to read, they help the scientist communicate with the layman concerning our environment, especially in those areas, such as the sea floor, that are not easily accessible.  With increasing population and all its attendant stresses on the planet, the need for this communication will become ever greater.  Fortunately, in the near future, with new techniques and with the use of computers, the cartographer will be able to respond to this demand and create oblique maps more quickly and more economically.”

A bunch of the examples below show the range of maps – which I count over 100 total, with a vast range in geography from Alaska, Washington and Oregon, California, and many from around the world.  The simplicity and elegance of the black and white showcases volcanic variants in the Pacific Northwest, two of my favorite places, Crater Lake and Mount St. Helens.

Some simple color accents coastal variation, in this case Willapa Bay in Oregon.

And the impact works as well for more urbanized zones, in this case San Francisco Bay.

The ability to use the oblique maps to carve out subsurface geology is interesting as well, in this case showing the Sierra Nevada mountains near Mono Lake.

And the bathymetry also, revealing hidden hydrology of bays and coastal waters.

The maps delve into the diagrammatic, as this one stood out to me.  The image hovering above the map shows the location of underway navigation transponders in the Pacific Ocean off the coast of Mexico.  The squiggly lines show the path of a ship that was mapping the bottom using sonar over multiple years.

The final section of the document highlights what are called ‘Cognitive Drawings’, which are somewhat more familiar slices of topography and geology that often appear in text-books, such as the evolution of river valley from sharper V-shapes to more subtle U-shaped valley systems.

Another hybrid map shows the relationship to the geologic features, in this case Ore deposits in Utah, with some simple accents, again revealing the underlying geological story from below.

The technical aspects of making these maps is admittedly less of a barrier today, but much of what comes from the digital realm lacks the tactile, illustrative quality shown here.  A post in Landscape+Urbanism on the art of Matthew Rangel comes to mind as a similar quality in new work, and the inspiration of graphic quality and communicative value is inspiring.  Worth a long perusal.  Enjoy!
