An Escape to Orcas Island in the Salish Sea


View from Turtle Back looking south west

My brother who belongs to a time share condo-resort group treated us to a week at Deer Harbor Resort on Orcas Island in mid January. As some of you might know, this is not far from our home in Bellingham, less than 20 miles as the crow flies. However, after an hour’s drive along the coast and another hour’s ferry ride through scenic islands, we could have been a thousand miles away.


And we really lucked out on the weather for mid January – mostly sunny with just a bit of rain at night.

The San Juan Islands are an archipelago that lies between the north western coast of WA state and Vancouver Island within the Salish Sea. On the map below Orcas Island is the horseshoe shaped one in the upper center of the map. You can see part of Vancouver Island with Victoria in the lower left side. Bellingham and Bellingham Bay where we live are on the upper right.

Deer Harbor where we stayed is the smallish inlet on the lower left side of the island, just west of West Sound

Nooksack River Part 2 – The History and Current State of the River

Chum Salmon Spawning on Chuckanut Creek


In part I of this series I described the Nooksack River from its headwaters in the North Cascade     Mountains through its course to the Salish Sea. I made the case that this river, along with others like it, were critically important to sustaining our icons of the Salish Sea  – salmon and orcas. Sustaining these icons is dependent in part on the health of these rivers that grow the fish which in turn feed our resident orca.   That is, healthy rivers are a necessary but not a sufficient condition for saving these critters. In this part I relate the history of the river, what has happened to it and why it is important today that it is restored to health and maintained.

On casual viewing, most of this river appears robust and healthy as seen in Part 1. Although much of river is in pretty good shape, closer examination shows that it is not totally pristine, especially as it pertains to our aquatic friends.  In general, the river is relatively healthy in its upper reaches and deteriorates progressively as it flows toward the sea which corresponds with the increased density of residential and agricultural occupation.  The story of the Nooksack River has been written numerous times of other rivers all across the continent from east to west. The Nooksack was one of the last to experience change as the area was not settled until the mid to latter part of the 19th C.

As noted, the Nooksack and Lummi Indians have flourished in this area along the river for thousands of years as it provided them with an abundance of everything they wanted and needed. The River teemed with salmon much of the year as each of the five species had spawning runs at different times of the year. They had nutritious roots of all kinds, including their namesake the “Nooksack” – Bracken Fern roots. In addition to salmon and roots, they had access to all the meat they could process including deer, elk, bear, beaver, mountain goats, cougar, birds, shellfish and more. They had dense forests of Douglas Fir and Western Red Cedar that provided lumber for their longhouses and canoes. For thousands of years they had lived as part of this natural system. They wanted for little.

Sketch of the Hawley family being ferried up the Nooksack by Indian Jim, a  Nooksack Indian Chief, to stakeout their Homestead (1872). Sketch by RE Hawley from his book “Skqee Mus — or Pioneer Days on the Nooksack,” 1945. RE Hawley is the child in the canoe.

Then in the latter 1850s and thereafter, the white settlers showed up and staked out homesteads along their river and in its watershed. Although they seemed to have gotten along well with local Indians and many became lifelong friends, the new settlers brought their ways that began changing the character of the land and therefore the river. The new homesteaders saw these natural wonders as something to be exploited and they were good at it.

The first homesteading took place in the flat prairie land surrounding the lower 30 miles downstream from where the south fork joined the main river. These prairies were covered with timber and large expanses of ferns, hence one of the early towns was named “Ferndale.”

The first thing the new settlers did was clear the forest and fern prairies for farmland. Since the river was their main mode of transportation, they first cleared and built along its banks. Because they wanted boats larger than dugout canoes to bring equipment and supplies up the river, they cleared out the natural log jams and beaver dams so they could get a steam boat upriver. This river excavation destroyed spawning and rearing habitat of the salmon.

Logged hillsides above the Nooksack valley with cleared forest along the river for farmland as they appear today. Logging and farming continue. Rain runoff of which we have plenty, eroded the hillsides and denuded land, sending mud and silt that interferes with salmon spawning beds in the river bottom. the river is seen running through the valley right to left.

The logs were skidded to saw mills which were situated on and powered by the river. The mills further stirred up the stream also destroying spawning grounds. The effects of this logging and farming denuded much of the river’s watershed leaving bare land without natural flora to slow the rain and flooding runoff. And it continues yet today although it is being better regulated.

This first settled part of the river regularly flooded the crops and is now mostly diked and dredged which destroyed the salmon habitat in the first 30 miles. The fish must swim at least 30 to 50 miles up each of the forks and feeder creeks to find adequate spawning beds. The growth continues with more farms, vacation housing developments, and logged hillsides but with increasing environmental regulation and government and NGOs to preserve the remaining waters.

A local district biologist for the Washington State Department of Fish and Wildlife described the river as unstable.

Rainstorms cause sudden, dramatic increases in river flows, followed by sudden drops. The flood stage destroys redds – the salmon egg nests – washing them away in the current or suffocating them with mud deposits. The drops destroy other redds the salmon laid when the water was higher, leaving them high and dry.

“Our biggest problem is egg-to-fry survival,” Barkdull said. “There’s basically no habitat left in the main stem … The Nooksack has been diked, ditched, straightened. Any evil you can commit on a river has been done to the Nooksack.”

That pretty well sums up the state of the lower reaches of the Nooksack River and as noted above, progressively less so as one moves upstream. As a whole the river is still quite viable. But there are big problems, the greatest of which is the loss of salmon.

Wild Salmon (except Sockeye) in most of the streams feeding the Salish Sea are listed as threatened according the Endangered Species Act.  Their numbers have plummeted in recent years and are nearly gone in many streams. Although all five species still find their way home and spawn in the Nooksack River or its tributaries, the numbers are small as is the case for most all streams leading into the Salish Sea.

Note that the greatest losses are to the fish of the Salish Sea with less loss out on the coastal rivers. 

Most salmon spend much of their first year or so in freshwater streams and this first year is critical to their ultimate survival. To the extent that their stream is healthy and with adequate food, they can grow larger and faster, traits that decrease their chances of being eaten by larger prey. Although more are lost while at sea after leaving the river, the early rearing conditions are also vital to their ultimate survival, the rate of which is diminishing significantly. Over the past 50 years, Salish Sea salmon and steelhead survival rates (returning to spawn) have shrunk from 3 per 100 to just 1 per 100. With that rate of loss these fish are clearly not sustainable for long.

Considerable study now confirms that stormwater runoff contains thousands of toxic chemicals including heavy metals and hydrocarbons all of which are highly toxic to fish. Exposed to concentrations of these chemicals salmon develop what is now called the “ Urban Runoff Mortality Syndrome.”

The river, the salmon and the ecosystem

The focus of the river preservation would appear to be on “save the salmon,” but the task is  more accurately: “Save the river and its ecosystem” and then you will save the salmon. These fish do not exist in isolation as they are part of a highly interdependent network of both flora and fauna, all parts of which must be preserved. While the stream’s biological health fosters the salmon, the salmon’s bodies also nourish other river denizens such as numerous macroinvertebrates. These stream critters include:


The number and types of macroinvertebrates present is a clear indicator of stream health.

You will see in the adjacent photo that the macroinvertebrates can be placed into three classes relative to their tolerance of pollutants: 1. Those that are intolerant, 2. Those that are somewhat tolerant, and 3. Those that can tolerate pollution and survive.

These invertebrates are important food sources for young salmon fry as they mature after hatching in spawning streams.  Other stream critters such as the American Dipper eat dragonflies, various larva, worms, small fish, (salmon fry) and fish eggs (salmon roe).

Salmon also nourish other critters and are referred to a “Keystone Species” in both aquatic and terrestrial environments in that their presence contributes to the survival and reproduction of some 40 other vertebrate species. These include the salmon themselves, trout, eagles, ravens, crows, Bear, wolves, coyotes, river otter and other mammals who feast on their eggs, carcasses, or their young.

Less spectacular but very important to the riparian environment is that the decomposing salmon carcasses also provide nutrients for algae in the streams, for trees and other plants along the stream. An interesting correlation has been found between size of a given year’s salmon run and the nitrogen levels found in tree growth rings along a river’s riparian zone. This occurs when the above animals drag salmon from the river to the adjacent woods where they devour the most nutritious portions of the fish, eating mostly their bellies and roe. They then leave the rest of the carcass to decompose into the soil.

Based on research on salmon streams in Alaska scientists have found trace nutrients from salmon bodies in mosses, herbs, shrubs, insects, song birds, bears and wolves.  Salmon feed the whole gamut of  wildlife that lives in or near their streams.

Salmon are important for sustaining their ecosystem which needs to be preserved or we will be left with barren, sterile, stinky and muddy water running to the sea which in turn will be barren and lifeless.

The effects of the  river’s pollution does not end when it reaches the salt water. It flows into the intertidal shores and continues its pollution.  The water’s high nitrogen and phosphorous content from manure and fertilizer runoff fosters rapid phytoplankton growth. Often, but not always these “blooms” of algae turn the water red and are referred to as red tides. Since they do not always turn the water red, they are more recently called Harmful Algal Blooms, (HABs). Shellfish consume and even thrive on these algae without harm but as certain algae accumulate, they can build to levels that are toxic and even fatal to humans and marine mammals. When the levels become toxic, all shellfish harvesting (recreational and commercial) is closed down. Currently the local beaches here are closed to Mussel harvest due to toxic levels of Paralytic Shellfish Poison.

Streaks of a Red tide or HAB in Bellingham Bay in August- nutrients plus warmth promotes algae blooms.

The pollution harms the river water and then the tidewaters (shellfish) and on into the Salish Sea affecting all marine life there including  fish and whales.

(This is not a local resident but he hangs out in the islands.) They are magnificent!

Most dependent on the salmon for their lives are the resident orca that have lived in the Salish Sea for eons. Our three local resident pods, designated: J, K, & L, rely solely on a salmon diet or they starve. Like their food source, salmon, the Salish Sea resident orca are in serious decline.

So What led to this threatening state of affairs?

In a nutshell the salmon habitat has been eroded, they have been overfished, polluted and poisoned. The issue is a problem with the entire ecosystem.  Following is an enumeration of some of specific causes of decline of this river. Clearly these are not unique to this river.

  • Artificially banked levees for the last 30 miles to protect farmlands from flooding preclude natural stream hydraulic processes. Clearing and dredging eliminated log jams or build up of logs and debris that naturally create deep pools and slow moving waters for spawning and rearing salmon fry.  Thus there are no spawning beds in the lower stretch of the river and no cool deep pools for fish to grow and mature.
    Dikes along the lower reaches of the Nooksack to prevent flooding farmland behind the trees. The river was not naturally this straight. It is more like a canal.

  • Fouled by mud flows and slides from surrounding logged hillsides.

  • Tributary creeks which are also spawning creeks have been crossed by roads built over with culverts that replace the natural streams for the salmon to navigate to get to their spawning areas. A recent Supreme Court decision upheld a lower court decision brought by 21 northwest tribes with treaty rights to salmon, that required the State to replace all road culverts that impaired returning salmon’s pathways to their natal streams. Replacement will take many years and cost about 4 billion dollars.

  • Agricultural product runoff such as animal manure and chemicals used as  fertilizers . Many dairy farms now have manure holding ponds to control runoff but these can leak and seep into the water table and into the river or a stream that feeds into the river. Septic tank leakage is another problem in the rural districts.

  • Stretches of the river are warmed by temperature change, loss of riparian zone trees and shrubs that shade the streams. The fish need cool and well oxygenated waters to thrive.
Salmon need the water cool, not too hot not too cold

  • Trash, including plastics and other toxic materials have been and continue to be  dumped at many points along the river. This has significant consequences for the fish as among many other toxins dumped. It has been recently determined that toxins from tires might contribute, among many other chemicals, to the death of Coho salmon that seem particulrly susceptible to effects of toxic storm run off.
The nailed on sign urges residents to stop dumping trash at river restoration site. 

There you have a description of the Nooksack river itself, its history from being a cornucopia to the Nooksack Indians and their related tribes for thousands of years and it having been nearly brought to its knees in 150 years of use and abuse.

The final episode (part 3) will describe many of the heroic efforts underway to reclaim and restore the river by County, State and Federal government agencies, NGOs and thousands of volunteers.


The Nooksack River – a Treasure to Preserve

North Fork of Nooksack River at Horseshoe Bend – Mount Baker National Forest

I’ve written of conservation efforts to preserve our local PNW waters and the salmonids that spawn and live in these streams. In these posts I have periodically mentioned the Nooksack but I have not featured this marvelous River as it deserves.

The Nooksack River is neither a large nor a long river by most standards as it runs only 75 miles from its origin in the glaciers of the North Cascade Mountains to its delta and mouth where it empties into Bellingham Bay to become part of the Salish Sea.

However, its relatively small size does not diminish its importance to the Pacific Northwest and its marine environment. The Nooksack is one of the few streams in the PNW that supports all five native pacific salmon species as well other salmonids such as steelhead and the rare Bull trout.

This is a photo diary on some unconventional looking trees I’ve observed in my various local wanderings. Some appear to be growing and prospering under rather difficult and stark conditions. Their shapes are often graceful and even artsy. Others are contorted, gross, gangly, and even eerie, but all are interesting.

What a 54,000,000 year old rock formation has to offer us today


Chuckanut Mountain

Chuckanut Mountain, Whatcom County WA

In stark contrast to the mountainous Pacific Northwest of today, during the Eocene epoch (~ 55 ~ 34 Million YearsAgo (MYA) it was quite flat. However just as today, the region then was lush with vegetation and interlaced with braided streams meandering from what is now Eastern Washington on to the Pacific Ocean. This was a tropical swamp with exotic plants and animals (although some would be familiar yet today). As the streams approached the ocean, they slowed and their sediments of sand, clay, and silt carried from huge rock formations to the east, settled out. Over millions of years these sediments accumulated, were compressed by gravity and tectonic forces, and solidified into immense geologic rock formations. This bucket is about one of these structures – the Chuckanut Formation made up primarily of sandstone, siltstone, conglomerate, and shale, with pockets of coal from the ancient compressed vegetation.

This formation is not only in my backyard it is under it as well. These  deposits extend to depths of nearly 20,000 feet in places. My focus here is on the Chuckanut Mountains which comprise 10 separate but related mountains (and hills) in and around Whatcom and Skagit Counties in northwest WA. In particular, I will focus mainly on Chuckanut Mountain itself (for which the formation was named) and a bit on Sehome Hill which is most directly in my back yard. In addition segments of this and related sedimentary formations are spread across the northwest, including the San Juan Islands and up into British Columbia.


What’s a Chuckanut? Although most agree that the name is derived from one of the local native languages, there are several interpretations for what “Chuckanut”, means.  I will go with the one from the US Geological Survey: “Long beach far from a narrow entrance.” Beyond that I do not know where the narrow entrance is.

Consisting of sedimentary deposits, these mountains would be expected to show numerous layers of the ages, accumulated over millions of years. And of course they do. Many of these layers now are tilted and folded indicating that they were subjected to tectonic and various geologic forces emanating  from several faults in the area. This formation is thought to have been folded about 40 mya, toward the end of the eocene epoch. So now these sedimentary remnants are hills and mountains, nestled as foothills of the Cascade range as well as being dispersed throughout local islands in the Salish Sea.

The sculpting process and creation of honeycombs called Tafoni

Tafoni are ellipsoidal, pan- to bowl-shaped, natural rock cavities. These cavernous weathering features include tiny pits, softball-sized cavities, truck-sized caves, and nested and cellular honeycomb forms. Tafoni typically develop on inclined or vertical surfaces and occur in groups.

Tafoni at water’s edge with concretion on the left.

The term “Tafoni” appears to originate from Greek and/or Latin with meanings variously of “tomb,” “window” or like openings.   
The erosive processes that creates these interesting tafoni are the result of weathering processes followed by erosion. Weathering involves various physical and chemical processes by which sand sized rock clasts and minerals that make up the rock, are loosened such as freeze — thaw cycles that expand spaces between grains, and blowing sand or sediments from water pounding on the rock.  Chemical processes too contribute such as water and carbon dioxide that weaken the mineral bonds holding rocks together.
Erosion then is the process that actually removes the weakened and loosened clasts including water pressure, wind, and the ever present gravity. Recall, these are typically on slanted or vertical surfaces. Weathering and erosion account for the loss of grains and the eating away of the rocks. However, the honeycomb form consists of eroded cavities with non-eroded walls (septa) that separate the holes. What appears to account for septa not eroding is that algae are present that protect the rock from the weathering processes. Surfaces without algae are eroded and leave the holes.
Note in the photos below that lighter, sand-colored surfaces are eroding whereas the darker, algae covered portions are not eroding. Also note that there are patches of lichen scattered around that also provide protection from weathering.

In addition to the tafoni, these same processes can work to form other designs such as mushroom-like formations with algae on top and the base being eroded.

These and many other patterns are found along the chuckanut formation components including the sandstone portions of the San Juan Islands, particularly those exposed directly to salt water.
