US Atlas Geology Screenshot

GEOLOGY is one of the twelve chapters of The National Atlas of the United States® which was coordinated and lead by USGS. In this volume we have incorporated 46 layers of information. These include Earthquakes, Volcanoes, Geologic Map, Mineral Operation, Magnetic Field, Waterways, County Boundaries and many more. Also we have included more detailed Geologic Maps from Open-File Reports of USGS (at the scale of 1:500,000 or larger) for 48 States.
