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.

I have found that with the oncoming winter ushering in shorter days and enduring rains, I have needed a greater sense of initiative to spend time outdoors naturalizing and experiencing the North Cascades for what it has to offer. It has become increasingly easy to allow myself respite from the day’s bite by spending time indoors with a pot of tea and a growing pile of books and work.

On a recent, clear day, I jumped at the opportunity to don my naturalist gear and head off down the road toward Diablo Dam with the intention of photographing, bird watching, or journaling, whichever happened to catch my interest based on possible encounters. I quickly became engaged in photographing minute details, focusing and framing things that I’ve walked by too often without taking time to notice. The bracken ferns have turned brown and curled through the progression of autumn, and are actually quite beautiful in contrast with green moss and the deepening blue tint of Diablo Lake.

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.

“That’s a cougar!” Well, maybe… We saw a brown blur slink over the crest of the island. Whatever it was, this was a big, brown mammal. One might say it was tawny. We had been paddling around Diablo Lake for a few hours and were now fighting the wind to get back to the Learning Center and some much deserved lunch, but our curiosity demanded that we pursue the mysterious animal that had somehow appeared on an island in the middle of a frigid lake in the shadowless sunshine of mid day.

Prys, draws, sculling, sweeps, posts and something called the Duffek, no these are not different ways to rid yourself of mosquitoes, they are just some of the 15 paddling strokes we learned to maneuver canoes safely and efficiently. Who knew there were so many?
