Resource Abstract:
The Painted Rock Mountains are about 15 miles west of the town of Gila Bend insouthwestern Maricopa County, Arizona (Fig.
1). The narrow north-south trending mountain range isapproximately 12 miles long and 2 to 4 miles wide. The range is easily
accessible by use of thepaved Painted Rock Road which crosses the historic Butterfield Stage Route (once the Gila Trail andthe
route followed by the Mormon Battalion in 1846), and extends northward to Painted Rock Dam.The study area encompasses parts
of the following 1:24,000 scale U.S. Geological Surveytopographic maps: Citrus Valley West, Theba, Dendora Valley, and Sentinel
NE. Bedrock consistsmostly of Miocene intermediate to felsic volcanic rock that has been intruded by a granitic pluton andis
overlain by basalt (plate 1; Fig. 2).Field work during February and March, 1993, coincided with filling of the Painted RockReservoir
to peak capacity and overflow of the spillway (the first time since the dam wasconstructed). The high water level is marked
on Plate 1. The nomenclature for the rock descriptionswas adopted and modified from both the U.S. Army Corps of Engineers
Painted Rock Dam 1987 RedBook report and U.S. Geological Survey Open-File Report 87-347.This project was jointly funded by
the Arizona Geological Survey and the U.S. GeologicalSurvey COGEOMAP program, contract #1434-92-A-1061.
