Grey Beard - Grey Beard's son Prairie Chief became a chief like his father. He helped guide the Southern Cheyenne through the transition to reservation life. This picture shows his dress in 1911. National Anthropological Archives Grey Beard, aka Wolf Grey, luckily escaped uninjured from the Sand Creek Massacre.
