Arizona Geological Survey (Tucson, AZ)Description
Geologic Map of the Imperial Reservoir Quadrangle, Yuma County, Arizona, and Imperial County, California, Scale 1:24,000. The report is part of a digital republication of a 1992 geologic map originally created by the Arizona Geological Survey with financial support from the U.S. Geological Survey. Preparation for republication was conducted by students from the University of Arizona with financial support from the National Geological and Geophysical Data Preservation Program, award number G24AP00258 and included the production of a new GIS geodatabase and a revised map layout. The following text report has not been altered and remains identical to the 1992 original, but there may be situations where unit names, ages, symbology, or other geologic information contained within this report do not match the information presented in the new map layout of the GIS geodatabase.Additional Links
