A (Sometimes) Overlooked Significance

Recently, I stumbled upon this question.

Honestly, it’s something that I think about regularly when I’m planning a trip to a national park. While people frequently visit parks and other protected areas to experience unique and special landscapes, sometimes we fail to see their forests for the trees, or even see their forests at all.

I think this is particularly true of North Cascades National Park and the adjacent recreation areas, Lake Chelan and Ross Lake. The region is most famous for its rugged mountain topography, which I must admit is quite pretty, but visiting here solely to see mountains risks missing some of the best, uncut forests left in the Pacific Northwest. I’m not implying that a visit to a park without admiring trees is somehow less worthy than my slow forest strolls. Far from it; national parks mean different things to different people. But, I find myself drawn to trees, no matter where I go, even among some of the Lower 48’s craggiest mountains.

The North Cascades are defined by their ruggedness, and the area’s vertical relief is impressively steep. Ridges and mountain peaks frequently rise above 7,000 feet while deep valleys incise the landscape to near sea level in some places. The Skagit River at Newhalem, for example, flows at 500 feet in elevation while several peaks ascend over 5,000 feet within a few miles. In Stehekin, Lake Chelan sits at a modest 1,100 feet above sea level, but within two and half horizontal miles of the lakeshore, Castle Rock reaches above 8,100 feet.

The rugged topography slowed the march of industrial logging into the mountains, so by the time the North Cascades National Park Service Complex was established in the 1960s and 1970s, much of the forest within the newly protected area had never been logged. In the park today, nearly every low elevation valley holds wonderful examples of wild, unmanaged forests.

Some of the most spectacular and significant trees are found along Big Beaver Creek, which flows southeast into Ross Lake. A section of trail about five miles from Ross Lake passes through a grove of thousand year-old western redcedar.  Preservation of these trees was the catalyst that stopped the expansion of Ross Dam.

Along their entire length, both the Big Beaver and Little Beaver valleys harbor incredible forests. The same goes for the Chilliwack River valley and Brush Creek area, so if you hike from Hannegan Pass to Ross Lake, you’re in for a spectacular forest hike.

Those places are remote, however, requiring most of a day’s hike just to get near them and several days of backpacking to traverse the valleys. Many other old-growth forests are more accessible. The Stetattle Creek Trail, which starts in the Seattle City Light company town Diablo, ends in a classic example of a climax forest on the west side of the Cascades. This trail is often overlooked and rarely busy. What it lacks in mountain vistas it makes up for in trees.

Hiking south from the Colonial Creek Campground, an easy four-mile round trip along Thunder Creek brings you through stately Douglas-fir and western redcedar. People often march through this section, barely stopping to look, as they have their sights set on up-valley destinations, but if you go plan some extra time to stop and admire these trees.

Disturbance—whether brought by fire, avalanche, landslides, or people—is a hallmark of this ecosystem as well. Many large trees stand as witnesses to past and current change.

Those that didn’t survive allow us to explore how the ecosystem may cope with future disturbance. I find myself pausing frequently in burned areas and avalanche tracks to admire how quickly the landscape can change.

Avalanches can sometimes devastate otherwise healthy stands of trees. This example comes from the upper Brush Creek valley.

Often overlooked and visited far less than the Highway 20 corridor, the Stehekin valley is the most diverse place in the park complex, both in terms of cultural and natural history. In Stehekin, you can find everything from a historic orchard to plants adapted to desert-like climates growing alongside old-growth groves.

Trees persist and even thrive despite the forces constantly working against them. They create vertical habitat, greatly increasing the landscape’s capacity to support life. They tell tales survival and struggle, longevity and adaptability. They are living witnesses to history and catalysts for conservation. North Cascades provides a rare opportunity to explore unmanaged, old forests—habitats that are becoming increasingly rare. And, if you can’t get here, just go to your local park or maybe even your back yard where, I bet, there’s a tree worthy of your attention.

Fishers Return to North Cascades

On an uncommonly sunny day in early February, I stood in a tract of old-growth forest not far from the Suiattle River to watch a missing mammal return to the North Cascades. With the return of the fisher, this area is one step closer to whole.

The fisher (Pekania pennanti) is one of the largest North American weasels. Adult females weigh four to six pounds and measure about 30 to 36 inches long, including tail, when fully grown. Males are about 20% larger, growing upwards of 13 pounds and nearly four feet long. Despite the name, fish are not a primary prey. Instead, fishers are wolverines of the forest. Highly arboreal, cylindrical in shape, and agile in motion, they are formidable predators of rodents, rabbits, hares, grouse, and other small to medium-sized animals.

One of the first fishers to be released on February 6. The common name, fisher, is probably a modern English language corruption of “fitch,” a Middle English term for the pelt of the European polecat (Mustela putorius), also known as the common ferret. Not coincidentally, the colonial Dutch fisse and visse as well as the French fiche and fichet, all words for the polecat, sound quite similar to fisher. (NPS Photo)

Fishers were functionally extirpated from Washington by the mid 20th century due to habitat fragmentation and, especially, unregulated trapping. Surveys in the 1990s and early 2000s failed to find evidence of any viable fisher populations. As a first step to recover the species in the state, a coalition of public agencies, tribes, and private organizations released fishers in Olympic National Park from 2008-2010. This was followed by similar efforts in Gifford Pinchot National Forest and Mount Rainier National Park from 2015-2017. The North Cascades National Park Service Complex and Mount Baker-Snoqualmie National Forest began to host the fisher’s return last fall, which is how I found myself standing in the woods with about twenty other people on February 6.

Fishers prefer mature forests with a high canopy, relatively large diameter trees, and an abundance of downed trees. Dead standing trees are particularly important to fishers, as they den exclusively in tree cavities. The release site for the fishers this day seemed particularly well suited to their needs.

Fortunately and conveniently, healthy populations of fishers remain in British Columbia and Alberta and they serve as the source for the restoration effort. Fishers from western Canada are also genetically similar to those that used to inhabit Washington. Canadian trappers were paid to capture live, healthy animals. The Calgary Zoo temporarily housed the fishers while veterinarians evaluated their health and surgically implanted tiny radio transmitters to assist biologists in tracking them.

Twelve hours before release, these particular animals were still in Calgary. At 1 a.m., the fishers were flown to Abbotsford, British Columbia where they were picked up by biologists and driven into Washington. By early afternoon, a gang of biologists and a few interested souls like me were unloading the cargo and carrying the fishers a short distance to the release site.

Fishers were transported in specially designed crates. Two fishers, separated by a partition, are in each crate.

Our group formed a semi-circle around the crates to watch the release. Conversations quieted to a whisper or died in anticipation as the crates were opened one at a time. To coax them out, a screened vent was opened at the top and a volunteer blew a puff of air into the container. I’m unsure if this was as annoying as someone blowing air into my ear, but the trick worked. The fishers shot out like a flash and bolted into the forest.

Six fishers were released that day bringing the total number currently released in the area to 24. The release efforts will continue until about 80 fishers are reintroduced to the area. Biologists will track, monitor, and study the animals to assess survival rates, identify where they go after release and where they establish home ranges, the types of foods they eat, and the diseases and parasites they suffer from.

The effort has a high chance of success. Reintroductions, however, are rarely so simple. Fishers, although not well known among the general public, are relatively non-controversial animals. They don’t evoke the same emotional reactions in people as grizzly bears or wolves, for example.

More than that, however, the forested habitats along the core and margins of the North Cascades are largely intact. Land managers needn’t take extreme, expensive, time-consuming measures to restore the ecosystem to a point where it could support fishers again. It could always support them. We just didn’t allow fishers to survive here.

Because prior generations had the foresight to protect places like North Cascades National Park and Glacier Peak Wilderness, we have the opportunity to restore fishers to land they once knew as home. Situations like these are becoming increasingly uncommon. People have fundamentally altered so much of the Earth to preclude the reintroduction of many extirpated species into their historic ranges. (There’s no substantial habitat available for bison in Iowa, for example.)

As humanity’s footprint grows, undeveloped landscapes are increasingly valuable, not for the resources we can exploit within them (including supposedly non-consumptive uses like solitude), but as repositories of biodiversity and ecosystem health. To adapt an idea from Thoreau, future generations, I believe, will measure our legacy not by what we invented and consumed, not by our material wealth, but by what we can afford to let alone.

I’ll probably never see any of these fishers ever again. Even if the population increases to hundreds of individuals, they’ll remain reclusive neighbors. If I’m lucky, I may find a track in fresh snow or its scat on a log. But even that doesn’t matter. I’ll know they are there and I’ll know the landscape is healthier because of it. The return of the fisher represents, at least in one small way, the success of our ability to let one place—North Cascades—alone.

The Origin of an Alpine Lake

Despite the area’s formidable topography, the North Cascades are filled with lakes. On a hike late last summer, I glimpsed how many of them formed.

Monogram Lake sits in a small basin perched a few thousand feet above Cascade River. At this elevation, just shy of 5,000 feet above sea level, it’s surrounded by blueberry meadows and scattered woodlands of mountain hemlock and Pacific silver fir. It’s an inviting place to camp for a couple of nights, no matter if you want to lounge by the lakeside or strengthen your quads further by climbing to the surrounding ridges.

I hiked there late last August hoping to watch black bears feeding on blueberries. The blueberries were reaching peak ripeness when I arrived, but I found no black bears or even any fresh bear sign, so instead of relaxing at the lake I decided to explore the surround terrain and take in some of the iconic alpine views that make the North Cascades so famous.

Not having a specific destination in mind, I was free to wander. These are my most favorite hikes, when I travel more to see what might lie in front of me instead fixating on a pre-determined destination.

Bushwhacking around the lake, I passed through quiet sedge-filled wetlands…

Here, I ate my lunch while contemplating the scene. It was a near perfect analog for the formation of the Monogram Lake basin.

Glaciers form when snow is compressed into mostly air-free ice and attains enough mass to deform and flow. Under the influences of gravity, ice deformation (high pressure within a glacier causes deeply buried ice to behave plastically), and lubrication from water at the its bed, glaciers move along the paths of least resistance. Due to their mass and size, they become powerful agents of erosion. They entrain rock, sand, and anything else as they flow. Forced along by moving ice, rocks at a glacier’s bed are especially erosive. Glacial erosion mills rock so effectively that much is pulverized into a microscopic powder called rock flour. This is the substance that gives glacial runoff it’s milky appearance and can color lakes turquoise.

Where ice had only recently receded at this particular glacier, the bedrock recorded plenty of evidence of the glacier’s past movement.

Many faint striations were scored into the bedrock near the glacier. The striations run roughly parallel to the hiking pole.

concentric gouges in metamorphic rock

Chatter marks are small, crescentic grooves formed in bedrock by rocks frozen in ice. The rocks chip the glacier’s bed as they are forced forward. The convex face of the marks point in the direction of movement.

Since glacial erosion is most pronounced at a glacier’s base, if topography forces ice through a pinch point then it causes the glacier to carve the underlying land more deeply and quickly than at the glacier’s sides, a process called overdeepening. As ice retreats, overdeepened basins often fill with water. This is the origin of fjords and deep lake basins as well as cirques high on mountainsides.

Monogram Lake occupies a cirque, a half open and steep-sided valley or basin on the side of a mountain. Instead of a clear lake surrounded by meadows, it was once filled with ice just like the basin below Little Devil Peak.

Uniformitarianism is a geologic principle that, in sum, means the key to interpreting the past is to understand processes that occur today. Excluding the three hydroelectric reservoirs in the Skagit Valley, glaciers carved the basins for nearly every lake in North Cascades National Park and Lake Chelan National Recreation area. Even though I wasn’t around to see Monogram Lake emerge in the wake of glacial retreat, all the evidence I needed for this process was right before me.

Gee Point

While browsing a map of the Mount Baker-Snoqualmie National Forest, I spotted what appeared to be a little used trail in a tract of the forest south of Skagit River. I quickly assessed whether it was worthy of my short list for exploration: Is it interesting and is it within cycling distance? With an affirmative yes to both criteria, I set off with my bike, Rocinante, to Gee Point.

I pedaled about eight miles south on the usually quiet Concrete-Sauk Valley Road. Only slightly rolling, this road was a good warm up for the rest of the day, which I knew would require a lot of climbing. Upon reaching the Finney Creek Road, I began a slow ascent through a mosaic of forested land—fields of stumps in recent clear cuts, thick second and third-growth stands, and occasionally a pocket of old growth forest.

In contrast to younger forest, old-growth stands are characterized not only by large and tall living trees, but also by a complex, uneven canopy and a relatively high amount of dead standing snags and down trees. Even from a distance, the old-growth can be easy to spot once you learn to look for these signs.

Large trees with an uneven canopy reveal a stand of old-growth trees on the edge of a former clear cut.

Most of these old-growth trees were inaccessible from the road (perhaps the only reason they remain standing), but a few other giants were spared the chainsaw. Perhaps too dangerous to cut, or perched precariously on the edge of a cliff, or already dead, these trees stood as the last remnants of the forest that used to be.

A few miles up the Finney Creek Road stands a giant dead Douglas-fir tree. These trees remind me that, with the exception of fire-maintained prairies and frequently flooded areas, nearly all of the Sauk and Skagit river valleys were covered with old growth trees.

Specific trees, like Sitka spruce, along Finney Creek also indicated this was often a wet place. Sitka spruce is typically found in areas with cool summers and high rainfall.

The North Cascades, however, experience a bi-modal climate. Its cool, wet winters stand in start contrast to hot and droughty summers, and I was soon reminded of the region’s aridity even as I cycled underneath a thick canopy of needles. As the road transitioned between gravel and broken pavement, the dirt was so dry I kicked up a rooster tail of dust anytime I gained appreciable speed and each pickup truck left a cloud in their wake. (I saw about a dozen motor vehicles in this stretch of national forest. With the exception of one ATV, all were pickup trucks.)

By the time I reached FS Road 1720, I was within a few miles of Gee Point, but I still had most of the climbing ahead of me.

It’s a lot steeper than it looks.

The road, now completely dust and gravel but pleasantly lacking washboards, switch-backed through young, even-aged trees as it gained elevation. The terrain was changing as I climbed and signs of winter’s harshness began to appear. I crossed through an avalanche chute at least three times, which gave me an excuse to stop and catch my breath as I admired the power of snow to snap trees in half.

Winter and springtime avalanches are a frequent occurrence in the North Cascades area, pruning any plant too tall or any too stiff to flex under their tremendous force. In summer, the brushy chutes are prime habitat for bears and I caught a glimpse of a black bear in this one.

The bright, hot sunshine and steepness of the road slowed my speed dramatically and I accumulated a sizeable escort of biting flies, but the views kept getting better, even with a slight haze from wildfire smoke.

To reach Gee Point though, I had to hike, so I locked Rocinante to a convenient fir tree at the end of the road and started walking. About a half mile in, I entered a beautiful, uncut forest dominated by large western hemlock and Pacific silver fir. At over 4,000 feet in elevation, which is not particularly high for the Cascades and in stark contrast to the tired burned out green of lower elevations, the forest floor had a noticeably fresh appearance.

The trail soon gained a ridge line and swung to the top of Gee Point where I was rewarded with a panoramic view.

 

The air, so calm and comfortably warm, easily could’ve induced a nap, but then I remembered that I was running low on water and time, so I reluctantly retraced my steps to the trailhead. After taking one final break to filter drinking water from Little Gee Lake, I bombed down the mountainside.

On the rapid descent, I was glad to have wide 700x38cc tires to handle the rough surface and working brakes to check my speed. The ride home was quick, taking me half the time to ride back compared to riding there. When I reached home, my lower legs were caked in a fine powder. They felt worked too, but it was a good kind of tired.
