Burial practices illustrated the two men's different outlooks. Custer believed a body should be buried in a long-lasting metal casket, thus removing the body from the ecological system by preventing bacteria from breaking it down and feeding it back into the soil. Crazy Horse believed in wrapping a body inside a buffalo robe and placing it on a scaffold on an open hillside, where the elements could break it down in a year or two. It would then come up again as buffalo grass, to be eaten by the buffalo, which would then be eaten by the Sioux, completing the circle.
