An extensive lahar (mud flow) on the east side of the mountain
In October 2004, students and faculty visited Mt St Helens and the channeled scablands in Washington. What the group did not expect was an actual eruption!
In fairness, geologists had noted an increase in activity within the mountain and had predicted that some kind of an eruption was likely, and on October 1st, 2004, half past noon, Mt St Helens did in fact erupt a cloud of steam and ash just as the class arrived at the Windy Point lookout.
The class also explored the area affected by pyroclastic flows during the 1980 eruption, hiking up Norway Pass to view Spirit Lake and Mt St Helens. The group then traveled across the Cascades to Yakima to explore the mega-geomorpho-logy associated with the Channeled Scablands.
This landscape of dry valleys and water-falls, enormous fluvial ripples and bare basalt surfaces were the product of fluvial erosion during the catastrophic drainage of glacial Lake Missoula and other damned lakes in British Columbia.
