About Craters of the Moon National Monument
The Bureau of Land Management's Craters of the Moon National Monument and Preserve is a 750,000-acre geologic wonderland, managed jointly with the National Park Service's Craters of the Moon National Monument and Preserve. Its central feature is the Great Rift, a 52-mile long crack in the Earth's crust. The Great Rift is a remarkably preserved volcanic landscape. Exposed fissures, lava fields, lava tubes, craters and cinder cones form a strangely beautiful volcanic sea on central Idaho's Snake River Plain. This landscape was formed by eruptions that started 15,000 years ago and represents the last period of volcanic activity in this area. The most recent activity occurred just 2,100 years ago, and is likely to continue. Craters of the Moon offers countless opportunities for hiking, camping
