Geologic Map of the Dome Rock Mountains SW 7.5' Quadrangle, La Paz County, Arizona

The Dome Rock Mountains SW 7 ½' Quadrangle is located just east of the Colorado River, east of Blythe, California and southwest of Quartzsite, in western Arizona. The map encompasses the western flank of the central Dome Rock Mountains and most of the piedmont that extends westward from the foot of the range toward the Colorado River. Geologic mapping was done under the joint State-Federal STATEMAP program, as specified in the National Geologic Mapping Act of 1992, and was jointly funded by the Arizona Geological Survey and the U.S. Geological Survey under STATEMAP assistance award #G14AC00424. Mapping was compiled digitally using ESRI ArcGIS software. Previously unpublished bedrock mapping by Richard Tosdal (former USGS employee) was incorporated into the map with minor revisions.
