Idaho

Rugged Terrain in Craters of the Moon National Monument and Preserve in Idaho. The National Park Service describes the park as "a vast ocean of lava flows with scattered islands of cinder cones and sagebrush." Early NASA astronauts trained here because of the terrain. Craters of the Moon sits on top of a rift zone, known as the Great Rift. Since rift zones represent weak areas in the earth's crust, it is common for them to be the site of volcanic eruptions.
