About this map

Ranching and mining interests dominate the high desert floor and mountain slopes of Pima County in this 1940 survey. Centered on Palo Alto Ranch, the landscape is defined by the braided channels of Altar Wash and Brawly Wash, which drain the surrounding highlands. The Sierrita Mountains to the east are heavily marked by early 20th-century mineral extraction, including the Copper Glance Mine (abandoned), Philimena Mine (abandoned), and Banner Mine (abandoned).
