Lassen Peak, Lassen Volcanic National Park

Lassen Peak viewed from the south

This view of Lassen Peak's southern slopes reveals that this
southernmost of the Cascade Range volcanoes
is one of the world's largest plug domes.
Note relatively smooth surface of large cliff in the center of image.
Like most domes, this one is surrounded by a large amount of talus
broken from the dome as it was extruded, and later by weathering.
Lassen Peak last erupted from 1914 to 1917,
making it the most recent volcano to erupt
in the coterminous United States
prior to the 1980 to 1986 eruptions of Mount St. Helens.
