Lewis and Clark Caverns State Park is located in Jefferson County, Montana. The park includes two visitor centers, ten miles of hiking trails, a campground, and its namesake limestone cavern.
The caverns may have been familiar to Native Americans since long before their discovery by Europeans, though there has been no documented evidence of human presence in the cave before the late 1800s. The Lewis and Clark Expedition camped within sight of the caverns on July 31, 1805, when they camped along Antelope Creek. In 1892, local ranchers Tom Williams and Bert Pannel saw steam coming from the caverns while hunting. Following the discovery, two people from Whitehall, Montana, Charles Brooke and Mexican John claimed that they had discovered the cavern in 1882. However, their claims are unsubstantiated. In 1898, Williams finally explored the caverns with some friends.
