The Shale Butte Wilderness Study Area is a Bureau of Land Management wilderness study area (WSA) in Lincoln County, Idaho. It covers 15,560 acres (6,300 ha). The WSA is located to the south of Craters of the Moon National Monument and Preserve.[1]
Shale Butte itself is located in the northeast corner of the WSA.[2] It is not composed of shale, but basalt lava of Pleistocene age.[3] The lava extends to the south from the butte to cover the eastern WSA.
The WSA is accessible only by unimproved roads and jeep trails, or by hiking.
