The map is a comprehensive update of the area's bedrock geology, combining existing studies with new data from aerial imagery, lidar, and fieldwork. It highlights various geological features, including the eastern edge of the Rock Springs Uplift and the Leucite Hills. The rock layers, dating from the Upper Cretaceous to the Quaternary periods, reveal a complex geological history, with rocks ranging from marine shales and deltaic sandstones to river and lake deposits, as well as rare volcanic rocks called lamproites.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Geologic mapRock Springs UpliftWamsutter ArchWashakie BasinGreat Divide BasinLeucite HillsReport
