Hidden under the city of Butte, you will find a deserted prison, shoe stores, a barbershop, and the once lively Rookwood Speakeasy, The Rookwood was a secret bar that thrived during America’s Prohibition days. These surprisingly well-preserved remnants from the early 1900s when the mining industry was in its heyday and 100,000 residents used underground areas joined by tunnels.
The limestone Lehman Caves were formed by millions of years of erosion from subterranean streams. Ensconced in Great Basin National Park, these caves were once the home of a secret speakeasy during Prohibition. Today you’ll see thousands of needle-like crystals and hollow, delicate stalactites nicknamed “soda straws.” You’ll also see “cave popcorn”, formed out of little lumps of calcite that truly resembles the real thing.
