    • Regolith-thickness contours for the shallow groundwater system in the Lower Gunnison River Basin, Colorado

    Metadata Updated: November 13, 2025

    This dataset consists of isopach contours showing the generalized thickness of regolith sediments (alluvium, colluvium, and weathered bedrock) overlying well-consolidated bedrock in the Lower Gunnison River Basin in Delta, Montrose, Ouray, and Gunnison Counties, Colorado. Regolith thickness was contoured manually on the basis of regolith-thickness values in the point dataset geologic_data. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Water Conservation Board.
