Please note: this class begins on Friday, March 28 at North Cascades Environmental Learning Center and ends on Sunday, March 30, at the Ross Lake Trailhead.
This new field excursion will explore the geologic history of the Ross Lake area during the annual drawdown, a period when the lake is lowered by Seattle City Light and vast new terrain becomes exposed. This unique landscape has been shaped by glaciers, the Skagit River and the Skagit Hydroelectric Project, and a wealth of natural history phenomena emerge every spring when the hidden landscape is revealed.
Jon Reidel, North Cascades National Park's geologist and leader of the Glacial Monitoring Program, will interpret our discoveries, and we'll see and touch sediments and buried wood from the last ice age, when a valley glacier flowing out of Big Beaver Creek blocked the Skagit River. We will ponder the incredible changes brought on by the Cordilleran Ice Sheet, including stream piracy, divide breaching and valley beheading. The ecological balance of the forested slopes and valleys along Ross Lake will be contrasted with the stark modern drawdown landscape, with its rapid rates of erosion and deposition.
Class will begin Friday night after a delicious meal served at the Environmental Learning Center with a presentation on the geologic history of of the upper Skagit Valley and North Cascades. The following morning we'll rise early, have breakfast, pack a lunch and head off to canoe and camp on Ross Lake. Participants will provide their own camping gear and food for the Ross Lake portion of the trip (the Institute has some gear to loan.) No previous experience necessary.
