2011 Map of Tortolita Mountains

About this map

Tortolita Mountains anchor this arid landscape of the Sonoran Desert, where deep canyons and seasonal washes dictate the placement of human activity. The map reveals a traditional ranching economy represented by the Palo Verde Ranch, Barriles Ranch, and McKenzie Ranch. Water is the defining resource here, traced through isolated points like Cochie Spring, Bass Spring, and Cottonwood Spring, along with landmarks like the Riddle Windmill and Crow Windmill. To the northwest, the Owl Head Buttes rise above a sparse network of roads such as Silverian Rd and Guild Rd. The southern portion of the quadrangle is dominated by the complex terrain of Fresnal Canyon and Bass Canyon, illustrating how the desert's topography has historically shaped movement and settlement in Pima County.
