Blue Mountain

Adopted, born-deaf stepson of the famous American Indian warrior and chief Sitting Bull, by Sitting Bull's fifth wife Seen-by-the-Nation. He used the Plains Indians Sign Language for regular communication. In "white" circles and on the reservation, he was sometimes called William Sitting Bull, though within his native Indian tribe he was properly known as Blue Mountain. The contemporary press also sometimes misidentified him as "Sitting Bull Jr.", though in fact it was his famous stepfather who was the "junior", Blue Mountain's step-grandfather being the first Sitting Bull. Blue Mountain may have been at the Battle of the Little Big Horn.
