The nearly vertical monolith known as Devils Tower rises 1,267 feet above the meandering Belle Fourche River. Once hidden below the earth’s surface, erosion has stripped away the softer rock layers revealing Devils Tower. Known by several northern plains tribes as Bears Lodge, it is a sacred site of worship for many American Indians. The rolling hills of this 1,347 acre park are covered with pine forests, deciduous woodlands, and prairie grasslands. Deer, prairie dogs, and other wildlife are abundant.
