The Black Hills is an isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, United States. Black Elk Peak, which rises to 7,242 feet, is the range's highest summit. It encompasses the Black Hills National Forest. It formed as a result of an upwarping of ancient rock, after which the removal of the higher portions of the mountain mass by stream erosion produced the present-day topography. The hills are so called because of their dark appearance from a distance, as they are covered in evergreen trees.
