Devils Tower National Monument, a unique and striking geologic wonder steeped in Indian legend, is a modern day national park and climbers' challenge. Devils Tower is in northeast Wyoming. The Tower is a solitary, stump-shaped granite formation that looms 1,267 feet above the tree-lined Belle Fourche River Valley, like a skyscraper in the country. Once hidden below the earth’s surface, erosion has stripped away the softer rock layers revealing the Tower.
