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

This dataset consists of values representing the generalized thickness (in feet) 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 in this dataset was derived from contours presented in the dataset rglth_contours.
