They are carving a likeness of Crazy Horse on the mountain and it was started about 50 years ago and they expect it to take another 130 years to complete. This is due to the fact that they accept no government funding for the project and can only do the work as private funds allow. There is a lot to see here as they have many displays on Indian history and such and they also have a movie that explains how the project got started and how they blast the mountain to form the sculpture. We also took a bus ride up to the mountain for a closer look. It was very interesting.
