Wilson Butte Cave is located on the Snake River plain in Jerome County northeast of Twin Falls and southeast of Shoshone, Idaho.

Listed on the National Register of Historic Places as an archeological site, it is maintained by the Bureau of Land Management (BLM).

A round bubble in appearance, it pops up from a flat wide bed of ancient basalt lava.

[2][3] Archeologists are fairly certain that the reason the cave was settled so early is that it was used as a base from which to hunt bison.

Two of the major excavations of the cave were conducted by teams led by Ruth Gruhn; one in 1959–1960 and one in 1988–1989.
