Abstract

Every 12 minutes, a cable operated skip car appears from beneath the desert surface of Arizona's Papago Indian Reservation. The Papagos have become quite used to the car, particularly those whose paychecks depend upon its regular appearance. The 24-ton capacity skip or tramcar hauls copper ore out of the North Decline of Hecla Mining Company's new mine about 30 mi south of Casa Grande. While there's nothing particularly glamorous about the skip itself, the railroad system upon which it travels is interesting because of the unconventional way it was built.
