Abstract
Description
This map shows the extent of various bedrock formations and quaternary deposits at the surface in the Chugwater 1:100,000 scale quadrangle area. This area covers the central portion of the Denver Basin that lies within Wyoming and a small part of Nebraska. The primary geologic units are of Pliocene, Miocene, Oligocene, and Upper Cretaceous age and include the Ogallala, Arikaree, White River, and Lance formations. This map is a compilation project, utilizing existing mapping, aerial imagery, and field checking to provide a spatial tool to better understand the geology of the study area at a more detailed scale and with consistent unit delineation.
