Precambrian Geologic Map of the Bradshaw Mountains, Battle Flat 7.5’ Quadrangle, Central Arizona v. 2.0 Anderson, Philip This report summarizes a collection of Precambrian geologic maps of the Bradshaw Mountains completed by Philip Anderson and including a foreword by Steven Reynolds, Michael Conway, Julia Johnson, Michael Doe, and Nyal Neimut, written in 2017. The original map is included along with the report. Other geologic maps from the Anderson collection preserved as part of this effort are published as DGM-282, DGM-284, DGM-286, DGM-287, DGM-288, DGM-289, DGM-290, and DGM-291. Note that not all maps from the original Anderson report were revised. The report is part of a digital republication of one geologic map within this collection, originally created 1977-1984 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 1977-1984 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.
