On August 1, 1881, Old Man Clanton was riding in Guadalupe Canyon in Animas Valley with other men. They were surprised by a group of Mexicans and attacked. At the end, many of the men were killed along with Clanton. Later that same year his son Billy would lose his life to a fierce gunfight on October 26, 1881 at the O.K. Corral. A year after his death, Clanton's sons, Fin and Ike, had his remains brought to Boothill Graveyard and buried next to his son Billy's.
