About this map

Samaniego Peak and the high ridges of the Sierrita Mountains anchor this arid landscape in Pima County. The terrain is marked by a complex network of drainage washes such as Fresnal Wash, Soto Wash, and Esperanza Wash, which flow from deep incisions like Fresnal Canyon and Ox Frame Canyon. In an environment where water is the primary challenge, numerous stock tanks and improved water sources are recorded, including Zapeda-Tank, Green Tanks, and Broke Tanks.

Human activity is concentrated along the eastern edge, most notably at the Ruby Star Airpark, while the southern reaches near Keystone Peak and Placer Peak suggest a history of prospecting. The transition from these high summits to the alluvial plains is traced by a series of named desert springs, such as Grays Spring, Sid Simpson Spring, and Bills Spring, which likely served as vital hubs for early ranching and transit through the canyon passes.
