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 8 miles (13 km) away from Mount Rushmore.
The sculpture's final dimensions are planned to be 641 feet (195 m) wide and 563 feet (172 m) high. The head of Crazy Horse will be 87 feet (27 m) high; by comparison, the heads of the four U.S. Presidents at Mount Rushmore are each 60 feet (18 m) high.
The monument has been in progress since 1948 and is still far from completion. If it is ever finished, it may be the world's largest sculpture.
