This point dataset contains geologic information concerning regolith thickness and top-of-bedrock altitude at selected well and test-hole locations in and near the Lost Creek Designated Ground Water Basin, Weld, Adams, and Arapahoe Counties, Colorado. Data were compiled from published reports, consultant reports, and from lithologic logs of wells and test holes on file with the U.S. Geological Survey and the Colorado Division of Water Resources. The U.S. Geological Survey prepared this dataset in cooperation with the Colorado Geological Survey and the Lost Creek Ground Water Management District.
