About this map

Saguaro National Monument dominates the eastern half of this landscape, where the peaks of the Tucson Mts rise sharply from the desert floor. The survey highlights the transition from the arid expanse of Avra Valley to the protected wilderness areas. Small-scale mining operations are scattered throughout the hills, including the Busterville Mine and Gould Mine, alongside the deeper industrial footprint of a large Quarry near Twin Peaks.

Recreational infrastructure is well-established within the Tucson Mountain County Park, featuring several dedicated sites such as the Signal Hill Picnic Area and Ez-Kim-In-Zin Picnic Area. Transportation and land use are defined by a network of ranch roads and trails, including the Hugh Norris Trail and King Canyon Trail, while isolated rural holdings like Rancho de Esperanza and the M-Z Bar Ranch mark the few points of settlement in the rugged terrain.
