Mount Baker in the northern Cascades rises 1,500 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.
