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.

To the east, the terrain levels out into the Santa Rosa Valley, where water management is critical to the local geography. The presence of West Gu Komelik Well and Drew Spring Well indicates the reliance on groundwater, while a network of check dams near the Anegam Wash shows efforts to control seasonal runoff. The settlement of Anegam sits at the southern edge, connected by unimproved roads that trace the natural contours of the valley floor.
