About this map

Mining operations and tribal lands define this arid landscape within the Papago Indian Reservation during the late 1970s and early 1980s. The Silver Reef Mountains serve as the dominant geological feature, hosting a concentrated cluster of industrial sites including the Silver Reef Mine, Magnesium Queen Mines, and the Copper Standard Mines. These workings, along with several Borrow Pits and a Quarry, point to a period of active resource extraction in Pinal County.

Residential life is centered around Chuichu and Shopishk (White Horse Pass), the latter located near a small Cem and Water Tank. The drainage patterns of Greene Wash and Silver Reef Wash cross the desert floor, while the Sawtooth Mountains rise in the southeast. Cultural features such as Ruins and several Prospect sites offer specific points of interest for those tracing the history of desert settlement and small-scale prospecting.
