Crazy Horse is currently being commemorated with the Crazy Horse Memorial in the Black Hills of South Dakota — a monument carved into a mountain, in the tradition of the Mount Rushmore National Memorial (on which Korczak Ziolkowski had worked). The sculpture was begun by Ziolkowski in 1948. When completed, it will be 641 feet (195 m) wide and 563 feet (172 m) high. Though still incomplete because of funding constraints, the sculpture has been criticized by some American Indian activists (most notably Russell Means) as exploitative of Lakota culture and Crazy Horse's memory as well as desecrating sacred ground.
