About this map

Corona de Tucson sits at a geographic transition where the Santa Cruz Valley floor meets the rising foothills of the Santa Rita Mountains. During the early 1980s, this area was defined by a mix of scientific research, military utility, and extractive industry. To the south, the Santa Rita Experimental Range and Wildlife Area occupies much of the landscape, established long before this survey for ecological study. The northeastern portion of the sheet shows the expanding residential footprint of Corona de Tucson, bordered by major corridors like Houghton Road.

The eastern terrain is marked by the complex topography of the Coronado National Forest, where resource extraction is evident at the Bluejay Mine Quarry and Jones Quarry. These sites, along with the Mt Fagan Ranch, reflect a traditional Western economy of ranching and mining persisting alongside modern federal land management. In the west, the Sahuarita Air Force Range indicates the region's mid-century military importance, while natural features like Sycamore Canyon provide drainage through the arid scrub.
