Geologic Map of the Huachuca City 7.5' Quadrangle, Cochise County, Arizona, v. 4.0

This map depicts the geology of the Huachuca City 7.5' quadrangle in Cochise County, southeastern Arizona, which consists almost entirely of upper Cenozoic surficial deposits. The map area is located between Benson and Sierra Vista along the western side of the upper San Pedro River Valley. The map area covers much of the southeastern piedmont of the Mustang and Whetstone mountains, part of the valley of the Babocomari River, and part of the northern piedmont of the Huachuca Mountains. It includes the small communities of Huachuca City and Whetstone, and the northern fringe of Fort Huachuca, a U.S. Army base. The quadrangle is roughly bisected by State Route 92, a major four-lane highway connecting the Sierra Vista area with Interstate Highway 10 to the north. The area was mapped during March through August, 2003. A 1:24,000 scale map is the primary product of this study. This map consists entirely of new mapping. The accompanying report describes rock units and other geologic features.Supercedes DGM-36, V 3.0Documents in the AZGS Document Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.
