About this map

Marana anchors the southern edge of this survey, where the desert floor meets the rising peaks of the Tortolita Mountains. The landscape is defined by a complex network of ephemeral drainages, including Guild Wash and Indian Well Wash, which channel seasonal water from high points like Jeffords Peak and the Falcon Divide. This 2018 study reveals a region where traditional ranching roots, evidenced by names like S McQueen Ranch Rd and S Carpenter Ranch Rd, coexist with modern recreational infrastructure such as the Honeybee Canyon Loop and Loop Trail.

Strategic water sources are critical features in this arid environment, with Cottonwood Spring, Bass Spring, and Cochie Spring scattered throughout the canyons. These natural springs have historically dictated movement and settlement patterns through Cochie Canyon and Fresnal Canyon. The map provides a detailed view of the Pinal Co Pima Co line as it cuts through the northern reaches of the range, separating the higher elevations from the Owl Head Buttes to the west.
