Things To Do


Great Rift is a relatively large Wilderness Study Area (WSA) contained within Blaine, Minidoka and Butte counties. This WSA also lies within the Craters of the Moon National Monument and much of it is adjacent to the Craters of the Moon Wilderness Area. Major access points include Arco, Minidoka and Carey.

The WSA contains unique and natural features including cinder and spatter cones, craters, lava tubes and kipukas. The WSA contains two distinct lava flows; the Craters of the Moon Flow and the Wapi Flow. The lava surface, kipukas and desert rangeland include examples of plant and animal communities in all stages of succession. Many of the kipukas are untouched and isolated, providing scientific and educational study sites.

BLM is recommending this area as wilderness because of its exceptional wilderness values and outstanding opportunities for solitude and primitive and unconfined recreation. The WSA contains many unique and natural volcanic features providing scientific and educational study sites.
