In 1924 the National Park Service began the job of protecting the park and welcoming people to experience this area. In 2000, the monument was expanded to include most of the Great Rift, the source of the lava flows that created this unique landscape.
Today's more than 750,000 acre National Monument and Preserve is cooperatively managed by the National Park Service and the Bureau of Land Management. There are 3 administrative units:
Craters of the Moon National Monument (National Park Service)
Craters of the Moon National Preserve (National Park Service)
Craters of the Moon National Monument (Bureau of Land Management)
The National Park Service preserves unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations. The Park Service cooperates with partners to extend the benefits of natural and cultural resource conservation and outdoor recreation throughout this country and the world.
