Cowheart Butte in rural Fremont County, Wyoming. Crowheart Butte was the site of a battle between the Crow and Shoshone American Indian tribes in 1866. According to legend, following a five-day battle for rights to the hunting grounds in the Wind River Range, Chief Washakie of the Shoshone and Chief Big Robber of the Crow agreed to a duel, with the winner gaining the rights to the Wind River hunting grounds. Chief Washakie prevailed, but he was so impressed with the courage of his opponent that rather than scalp him, he cut out his heart and placed it on the end of his lance.
