Lassen Peak, Lassen Volcanic Park, California

Lassen Peak (10, 456 feet), from the east, Lassen Volcanic Park, California. Lassen Peak, the southern-most volcano of the Cascade Range, is a volcanic dome formed of dacite. The sparsely-forested area in the foreground, called the Devastated Area, was destroyed by a lateral blast and ensuing large mudflow stemming during the 1915 eruptions. Lassen Peak last erupted in 1921. Photograph by R. Forrest Hopson.
