Geologic Map of Wyoming
The WSGS has released the Geologic Map of Wyoming, an important visual tool displaying a variety of geologic features, from different kinds of rocks and faults to the state’s river basins and mountain ranges. The 1:500,000-scale wall map includes a separate legend sheet. The geologic map is a new and improved presentation of the original hand-scribed map created in 1985 by authors David Love and Ann Christiansen of the U.S. Geological Survey. Read more...
