Map Showing Total Thickness of the Fox Hills-Lower Hell Creek Aquifer, Montana

Description: Introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the total thickness of the Fox Hills-lower Hell Creek aquifer. Other maps show the altitude of the top (Feltism 1982a), cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) in the Fox Hills-lower Hell Creek aquifer. These maps are part of a series that describes the … more
