In 1947, sculptor Korczak Ziolkowski accepted a commission from the Sioux to carve a likeness of Crazy Horse in their sacred Black Hills. Ziolkowski died in 1982; with luck, his great-great-grandchildren will live long enough to dedicate the finished sculpture.
Unlike Mt. Rushmore, Crazy Horse is being sculpted in the round. The finished creation, depicting a mounted Crazy Horse pointing to the surrounding land, will stand 563' tall (higher than the Washington Monument) and 641' long. All four Mt. Rushmore heads would fit inside Crazy Horse's head.
