The Geology Library houses a collection of USGS topographic maps at scales of 1:24,000, 1:100,000, and 1:250,000. All editions for Wyoming and only the most current editions for other states are retained. Maps are filed by state and then alphabetically by sheet name in the Map Room. Search GNIS by placename.
Geologic Maps
Geological Maps are published by the Federal Government (USGS), state geological surveys, and professional societies. The Library focuses collection efforts on Wyoming and the Rocky Mountain region. The USGS publishes geological maps of all states and many countries. Good sources for identifying published geological maps are GeoRef and the National Geologic Map Database. Once you have identified a map of interest, search the library collections to determine if the Library owns a print copy and to find the location and call no. Many state geological surveys have maps available for download on their websites at no charge. The Geology Library also owns many maps from state surveys.
BLM Surface Management/Mineral Management Maps
BLM maps show surface and sub-surface mineral rights ownership status (private land owners are not indicated). BLM maps are currently published at a scale of 1:100,000, covering a 35 x 50 mile area. See the index map for Wyoming to determine the appropriate sheet.
Political & Thematic Maps
Maps showing political and administrative areas, energy, soils, climate, and transportation are located in the Map Room and on the Map Shelves. Most are organized by U.S. state, country, and regions using Library of Congress call numbers. Use the call number guides in these areas to identify the appropriate call numbers for the location you are interested in. CIA country political maps are in the Map Room Government Document drawers; these are filed alphabetically by country under the PREX heading.
