“”Crowheart Butte, the isolated butte north of the highway, is composed of claystone and sandstone of the Eocene Wind River formation. Behind its name is a colorful story. In 1866, Indian tribes in the area fought a battle to establish supremacy over hunting grounds in the basin. Chief Washakie led the Shoshone and Bannock tribes against the Crow Indians, led by Chief Big Robber. In an effort to save lives, Chief Washakie suggested that he and Chief Big Robber fight alone at the top of this butte — the winner would eat the other’s heart! Washakie won and the butte was named “Crow Heart.” In his old age, Washakie was asked if he actually ate Big Robber’s heart; he replied “youth does foolish things.”
