Devils Tower National Monument

Close Encounters of the Third Kind made Devils Tower a pop culture phenomenon, and for good reason, as it's one of the most mysterious national parks.

Rising 1,267 feet above the Belle Fourche River, Devils Tower has long been a beacon, attracting people and capturing their imaginations since prehistoric times. Today, it continues to hold many meanings for people including American Indians, local ranchers, rock climbers, and thousands of visitors.

Using the authority of the newly created Antiquities Act, President Theodore Roosevelt proclaimed Devils Tower America's first national monument on September 24, 1906.
