1990 Map of Drew Spring Well

USGS Topo · Published 1990

About this map

The Cimarron Mountains and Sheridan Mountains dominate the western half of this 1990 survey, rising sharply from the desert floor of the Papago Indian Reservation. This landscape is marked by a history of mineral exploration, with numerous small-scale operations including the Montazona Mine, Blackjack Mine, and Oro Grande Mine scattered along the mountain flanks. These sites, along with various prospects, adits, and a mine shaft, suggest a period of active geological testing and extraction in this remote corner of Pima County.
