Mt. Adams

Off into the distance we could see Mt. Adams.

Mount Adams stands astride the Cascade Crest some 30 miles due east of Mount St. Helens. The towering stratovolcano (12,276 feet) is marked by a dozen glaciers, most of which are fed radially from its summit icecap. In the High Cascades, Mount Adams is second in eruptive volume only to Mount Shasta, and it far surpasses its loftier neighbor Mount Rainier (which is perched on a pedestal of Miocene granodiorite). Adams's main cone exceeds 44 cubic miles, and at least half as much more was eroded during late Pleistocene time from earlier high-standing components of the compound edifice: peripheral basalt adds another 15 cubic miles or so.
