Baker Volcano, USA

Mount Baker stratovolcano in the North Cascades rises 1500 m above a dissected basement complex of metamorphic and sedimentary rocks, exposed at Dock Butte in the foreground.

On the left skyline is the glacially eroded core of the Pleistocene Black Buttes stratovolcano, a predecessor to Mount Baker.

From left to right, the Deming, Easton, Squock, Talum, Boulder, and Park Glaciers drape the volcano's flanks.
