Lewis and Clark Caverns, Limestone show cave in Jefferson County, Montana
Limestone formations extend through multiple chambers across a vertical distance of 1,000 feet in this northwestern United States cave system.
Dan Morrison discovered and developed the cave in 1900, naming it Limespur Cave before the federal government claimed ownership through legal proceedings.
The Civilian Conservation Corps workers constructed pathways and infrastructure during the 1930s, making the caverns accessible for public exploration.
The cave maintains a constant temperature of 50 degrees Fahrenheit throughout the year and requires visitors to climb 600 steps during guided tours.
Steam rising from the cave entrance led hunters Tom Williams and Bert Pannel to discover these formations in 1892.
