About this map

Pedregosa Mountains dominate this 1980s landscape, characterized by dramatic desert landforms and deep drainage systems. The map captures a section of the Coronado National Forest, where prominent peaks like Packsaddle Mountain and the distinctive Castle Dome rise above the surrounding terrain. To the south, Poverty Flat suggests the modest nature of human encampment in this arid environment, while evidence of extraction persists at the southern Quarries and a scattered Prospect.

The hydrologic network is intricately detailed, showing how seasonal waters have carved the land into features such as Mesa Draw, Big Bend, and Tom Ketchum Canyon. Permanent water sources are sparse, noted only by specific labels like Walnut Spring. This survey, compiled from 1979 aerial photography, provides a clear view of the area's physical geography before modern changes, documenting the transition between high desert elevations and the rugged canyons of Walnut Canyon and Deep Well Canyon.
