About this map

The Silver Bell Mountains and surrounding desert basins define this high-altitude 1994 topographic study of Pima County. Industrial activity is prominent at the Silver Bell Mine, where extensive Tailings Ponds and open pits mark the landscape north of the Roskruge Mountains. To the east, the agricultural and transport corridor along the Southern Pacific RR connects Marana, Rillito, and Cortaro near the Santa Cruz River.

Large protected areas and indigenous lands occupy the central and western reaches, including the Papago Indian Reservation (Tohono O'odham) and the Saguaro National Monument. Small settlements like San Vicente, Ko Vaya, and Pan Tak are linked by a network of desert washes such as Aguirre Wash and Brawley Wash. The map documents the spatial relationship between these tribal lands, the rising suburbs of the Tucson fringe, and the aviation hubs at Avra Valley Airport and Ryan Field.
