Geologic Map of The Narrows 7.5' Quadrangle and the Southern Part of the Rincon Peak 7.5' Quadrangle, Eastern Pima County, Arizona, v. 2

The study area is located ~40 km southeast of downtown Tucson, and is bounded by the Rincon Mountains on the north, the Empire Mountains on the southwest, and the Whetstone Mountains on the southeast. The map area covers The Narrows 7 ½' Quadrangle and the southern half of the Rincon Peak 7 ½' Quadrangle. The area was mapped during October 2000 through April 2001 as part of a multiyear mapping program directed at producing complete geologic map coverage for the Phoenix-Tucson metropolitan corridor.
