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.

Craters of the Moon is a HUGE national park! It is over 1,100 square miles (over 750,000 acres) which is roughly the size of Rhode Island. The young lava flows that make up the bulk of the Monument and Preserve can clearly be seen from space.
