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 co-managed by the National Park Service and the Bureau of Land Management.
