The Crazy Horse Memorial is a mountain monument under construction in the Black Hills of South Dakota, in the form of Crazy Horse, an Oglala Lakota warrior, riding a horse and pointing into the distance.
The memorial consists of the mountain carving (monument), the Indian Museum of North America, and the Native American Cultural center. The monument is being carved out of Thunderhead Mountain on land considered sacred by some Native Americans, between Custer and Hill City, roughly 10 km away from Mount Rushmore.
The sculpture's final dimensions are planned to be 195 m wide and 172 m high. The head of Crazy Horse will be 27 m high; by comparison, the heads of the four U.S. Presidents at Mount Rushmore are each 18 m high.
The monument has been in progress since 1948 and is still far from completion. If finished, it will be the world's largest sculpture.
