The U.S. Geological Survey has just published a detailed and beautiful new full-color “Geologic map of the Bodie Hills, California and Nevada.” The map can be downloaded for free, here: http://pubs.usgs.gov/sim/3318/. Map Sheet 1 is the map itself, and Map Sheet 2 is the explanation of map units. Several other files provide related information.
The Bodie Hills are mostly Miocene and Pliocene volcanic and sedimentary rocks, with a variety of Quaternary surface deposits. Granitic basement rocks, mostly Cretaceous and Jurassic, are prominent in the Masonic Mountain, Aurora Peak, and Rattlesnake Gulch areas. As a teaser, here’s a small part of the map, showing the Aurora–Brawley Peaks area.
