Snow clings to the jagged sides of Devils Tower National Monument in Wyoming. This astounding geologic feature is considered sacred to the Northern Plains Indians and other tribes, who called it “Bear’s Tipi” or “Bear’s Lodge.” Hundreds of parallel cracks make it one of the finest crack climbing areas in North America. Devils Tower entices us to explore and define our place in the natural and cultural world. Photo by National Park Service.
