Texas Canyon, a valley in southeastern Arizona east of Benson between the Little Dragoon and Dragoon mountains, is famed for giant granite boulders that have long attracted photographers and rockhounds. It also holds a layered human history. The Butterfield Overland Mail stagecoach route ran through the canyon from 1858 until service stopped in 1862 with the outbreak of the Civil War. The area was part of the Chiricahua Apache range, and Cochise's last stronghold was nearby in the Dragoon Mountains in the mid-1870s. Since the 1930s, it has also been home to the Amerind Foundation founded by William Shirley Fulton.
