Teaching landscape watercolor in summer and autumn at the North Cascades Environmental Learning Center on Diablo Lake encompasses everything I love best: peaks, forests, water, wildlife and enthusiastic fellow artists. When I am at home in Seattle, I seek out the quieter parks nearby, especially Union Bay Natural Area, also known as the Montlake Fill, which seems to have a little of all those things I treasure in the North Cascades.

It is surprising that a place so rich with wildlife is less than a mile from the University Village shopping center, right off Sandpoint Way east of the University of Washington, and adjacent to its enormous parking lots. You can be entirely unaware of all that bustle, although in winter you can see the buildings to the north through a grove of leafless cottonwoods. The Natural Area is on land owned by the University of Washington.

In 1895, Lake Washington was lowered and the University was moved from downtown to its present site, which included the marshy land exposed by the lowering of the lake. At that time no one could think of a way to use this area, so in 1926, when the City of Seattle asked the University if they could pay to use it as a dump and a landfill, the university agreed. In 1971, the Fill finally closed. In 1977, the University’s regents approved a plan that would create an arboretum and keep a natural area for the study of horticulture, as well as a wild area.

They are rare visitors, and that year they graced us with their presence for several days—seeing them inspired the design for this woodblock print.

The sheer power of water was apparent in the North Cascades this last weekend after a recent Pineapple Express hit the Northwest. Warming temperatures combined with a significant amount of rainfall fell onto several weeks worth of snow in the Cascades. Consequently, mountain creeks filled to the brim and several landslides covered Highway 20, closing a stretch of this road between the towns of Diablo and Newhalem. Several M.Ed. graduate students and our graduate coordinator were staying at the North Cascades Environmental Learning Center and in the town of Diablo, and got to see this dynamic shift in nature first-hand.

At the Learning Center, the recent weather demonstrated how quickly land is shaped by water as we watched Sourdough Creek quadruple in size Sunday afternoon. This was an amazing shift to see as Sourdough typically runs as a trickle in late summer to a swiftly-flowing mountain creek in late spring. Sourdough Creek runs next to the Learning Center’s parking lot under a “Texas dip,” a removable piece of roadway designed to prevent washout. But this road feature was barely recognizable as the creek filled with brown, fast-running water that undercut the bank, causing large chunks of earth to collapse and wash away into Diablo Lake.

When I awoke the other morning to see a forest of snow-covered trees, I felt just as excited when I made the same discovery as a child in the winter season. A fresh layer of snow had fallen overnight, changing the already beautiful landscape of the North Cascades Environmental Learning Center into a wintery scene. It appeared to have only snowed an inch or two at the lower elevation, but I was just as happy as if it had snowed more.

The snow always lifts my spirits and I am compelled to get outside and play in the white stuff. Coincidentally, my fellow graduate students and I had previously arranged to spend the morning searching for animal signs and exploring our backyard near the Learning Center together before we departed for Thanksgiving break. With newly fallen snow, we were not sure if we would find many obvious signs of activity from our wildlife neighbors. We were fortunately proven wrong, and surprised at what we found.

We were very excited to have Cliff Mass as one of our instructors for the 2010 Northwest Naturalists Retreat, and then thrilled when he posted a piece about the weather in the Learning Center’s neighborhood on his popular blog:

A green-blue mountain lake with towering mountains, snowfields and glaciers, as well as a fascinating meteorology–the is what I found during a pleasant stay this weekend at the North Cascade Institute this weekend, where I was one of the instructors for their Naturalist Weekend Retreat. The location of this beautiful facility is on Diablo Lake (see maps below), behind Seattle City Light’s Diablo Dam. A very pleasant place to take environmentally oriented classes or to use as a base for exploring the North Cascades.

The lake has a green-bluish tinge due to the very fine particles produced by the surrounding glaciers (glacial flour). Why greenish blue? Why is the sky blue? A similar reason–what is known as Rayleigh scattering of visible light. Very fine particles scatter short wavelengths (like blue or green) far more than longer wavelengths (like red or yellow). Thus the shorter wavelengths are scattered back to your eye producing the bluish or greenish tint.

Some of the most exceptional meteorological features of this location are the diurnal (daily) winds. Nearly every day in summer the winds pick up on the lake around noon, with the flow accelerating up to 12-25 mph, often producing whitecaps. The wind is from the west, flowing directly up the Skagit  River valley (see map above). During my stay I noted a strong correlation between this westerly wind and the pressure difference across the Cascades; when eastern Washington pressure fell relative to the west, the winds accelerated. Thus, the winds appeared to be gap winds, which are roughly proportional to the pressure difference across the gap. The interesting thing for me, is although the gap is very clear to the west (the Skagit River Valley), to the immediate east there is considerable blocking terrain until one gets to Mazama. But clearly the air rushing up the Skagit is going somewhere as it pushes to the east. Since the pressure difference increases during the day (eastern Washington heats up, air there becomes less dense, and thus the pressure falls), the wind strengthened late morning into the afternoon.

Summer has finally arrived at the Environmental Learning Center! Diablo Lake has regained its characteristic green color, peregrine falcon fledglings are learning to hunt near the dam, a new fawn is sporting spots around campus, and the tenth cohort of graduate students have begun their academic journey.

Cohort 10 began classes in Bellingham on June 22nd. The eleven students who are enrolled in the graduate program come from a variety of backgrounds, ranging from education to environmental science to multi-media studies. Their summer coursework consists of three classes: Introduction to Place-Based Education, Resource Issues in the North Cascades, and Cultural History in the North Cascades. These courses are interwoven into a series of field excursions in the region, supplemented by readings, projects, and discussions in classes at Western Washington University.

Spring’s presence is not the only thing that North Cascades Institute is welcoming at the Environmental Learning Center this season.

As the season continues to reveal itself more each day, whether it be through the scent of black cottonwood blossoms dancing on a wind from Diablo Lake or the more frequent blue skies serving as a backdrop for the steep, snow-coated hillsides of Pyramid and Colonial Peaks, an even newer welcoming has taken place in the North Cascades.

On March 16th, for the spring staff retreat, a plethora of Institute staff from both up river and down valley gathered on the shores of Diablo Lake to welcome the Institute’s newest family member—the big, BIG canoe. This 36-foot canoe—made by Clipper Canoe in Abbotsford, British Columbia—holds up to 18 paddlers on any given excursion. Its black exterior, red interior and wolf-like decorative bow are indicative of the traditional design and coloration of canoes in the Coast Salish culture.

Move over United States Postal Service, neither rain, nor snow, nor sleet, nor hail shall keep the graduate program from connecting with this place.

Alumni and current students gathered November 6^th through the 8^th for the First Annual Graduate Program Alumni Reunion. Along with friends, family, and faculty of the graduate program, we enjoyed an energetic dinner filled with reminiscing and laughter. Known for our friendly competitive nature, we engaged in a battle of wits and strength—a trivia night to remember. From North Cascades knowledge to a raingear relay, from a campfire song sing-off to mystery granola identification, our wisdom and vigor was challenged. Conquering the final night-time scavenger hunt mission, the winning team received pennywhistles, which with they will attempt to master in the same fashion as our own Executive Director, Saul Weisberg.

The next morning, we headed out into the elements for a photo scavenger hunt. Given a list of tasks, each team gained points for photos that captured the completion of these tasks, awarding points for difficulty, creativity, and bribery. As typical Northwest torrents poured on us, cameras captured glimpses of team hugs, reenactments of the Davis family, nature art, and notable places from Mountain School in Newhalem. Also known for our determination and perseverance, many grads and alumni ventured into Diablo Lake in order to earn the most points. The winning team, relentlessly tough, achieved victory by swimming under the glacial waters of our green lake on a day where temperatures would drop and snow would fall.

Backpacking in the North Cascades is great, but last weekend I wanted to do something different. I decided to try canoe camping. The Environmental Learning Center on Diablo Lake was the perfect starting point for my three-day trip.

We here at Chattermarks are not the only people blogging about the North Cascades and our awe-inspiring wilderness campus on Diablo Lake; I stumbled upon this fine story at www.pacificnwseasons.blogspot.com recently:

After several months working toward a big project deadline, I’m in dire need of some downtime in a beautiful setting. Give me craggy, towering mountain peaks, expanses of water, or lush green forests and I’m happy. Give me all three together and I’m very happy. So I check out the schedule for my favorite Northwest place that combines them all—the North Cascades Institute (NCI) Environmental Learning Center on Diablo Lake, a 2+-hour drive northeast of Seattle.

Just a week after my deadline, NCI is offering a Diablo Downtime weekend of yoga, slow food, canoeing, hiking, and relaxing. I sign up immediately.

Last week the Cohort 8 graduate students headed to the islands of Diablo Lake for class.  The topic of the day: island biogeography, which is the study of the distribution and abundance of species on physical and habitat islands.  I won’t go into too many details, although I think the study of habitat islands is fascinating, what I want to share with you are pictures of what we discovered.
