Craters of the Moon National Wilderness Area
Administered by the National Park Service, this wilderness encompasses more than 80% of Craters of the Moon National Monument. Included in this 43,243 acres is a portion of Idaho's Great Rift, which produced the most recent volcanism in the state. The area is populated with cinder cones, lava tube caves, and lava flows. Some sagebrush, bitterbrush and limber pine grows among the cinder gardens. Craters of the Moon wilderness was designated in 1970. Some of the nearby towns are Arco and Pocatello, Idaho.
