1. Deadwood, South Dakota

Nestled deep in the Black Hills, Deadwood erupted during the Gold Rush, drawing a wild mix of fortune-seekers, gamblers, and notorious outlaws. The lure of instant riches filled the muddy streets with restless ambition—and danger. Famed for the murder of Wild Bill Hickok in a local saloon, Deadwood’s turbulent history became a symbol of both lawlessness and opportunity on the American frontier. Its legacy remains woven into the fabric of the Wild West’s most enduring tales. Learn more from Smithsonian Magazine.
