Lava Beds National Monument

Volcanic activity spewed forth molten rock and lava creating a rugged landscape, which was used as a natural fortress by Native Americans in the Modoc Indian War, 1872-73. For millions of years the volcano erupted, creating an inhospitable landscape. This volcanic activity formed cinder cones, shield volcanoes, strato volcanoes, lava tubes, both Aa (rough) and Pahoehoe (smooth) lava, spatter cones and chimneys. The youngest cinder cones being around 1,000 years old. But by far the most unusual is the high number of lava tubes in this area.

Acreage: 46,559.87 all federal
wilderness area: 28,460 acres.
