Bear Den Butte Wilderness Study Area


The Bear Den Butte WSA is characterized by two distinct landforms. The edges of the WSA are composed of an older lava flow covered by wind-deposited soils up to five feet deep. Topography is flat to gently rolling broken by occasional buttes and dry lakes. In the center of the WSA, a younger lava flow overlies the rolling topography. This "aa" (the Hawaiian word for "hard on the feet") lava flow has clinkery and jagged surfaces and contains a variety of holes, blisters, pressure ridges and collapse features.

Visitation Information

In Idaho, BLM manages nearly 10,000 acres of public lands in the Black Den Butte Wilderness Study Area. Outstanding opportunities for solitude can be found here. The rugged volcanic features and desert environment have opportunities for camping, hiking and hunting. Access to the WSA is from designated roads within the expanded Craters of the Moon National Monument. There are no associated recreation developments.
