The Craters was originally designated as a national monument in 1924 to preserve the very concentrated and unusual volcanic features. In 2000, President Clinton expanded the monument to include virtually all of the the Great Riff. Subsequently, Congress in 2002, designated the area the Craters of the Moon National Monument and Preserve.
The Craters is managed both by the National Park Service (NPS) and by the Idaho Falls and Shoshone Districts of the the Bureau of Land Management (BLM). Three managements programs are in effect depending on the area.
