Lewis and Clark Caverns State Park is located in southeastern Jefferson County, Montana. The primary feature of the park is its namesake limestone cavern. The caverns have been familiar to Native Americans since long before their discovery by Europeans. The Lewis and Clark Expedition camped within sight of the caverns on July 31, 1805, when they camped along Antelope Creek. The cavern was first discovered by non-Native Americans in 1882 by two people from Whitehall, Montana, Charles Brooke and Mexican John.

In 1892, local ranchers Tom Williams and Bert (or Burt) Pannel saw steam coming from the caverns while hunting. In 1898, Williams finally explored the caverns. Williams wanted to begin giving tours
