The Crazy Horse Memorial is the world's largest mountain sculpture in progress. It is in the Black Hills of South Dakota, USA. The statue depicts Crazy Horse, a famous Lakota warrior. Korczak Ziolkowski started the project in 1948 at the request of Chief Henry Standing Bear and other Native American elders. The statue is meant to be a memorial to the spirit of Crazy Horse as well as the Native American people.
Ziolkowski believed in individual initiative and private enterprise, and as such, never accepted government funding. He continued to work on the memorial until his death in 1982.
