Hydrology of the Wibaux-Beach Lignite Deposit Area, Eastern Montana and Western North Dakota

Description: From objectives and scope: This study was undertaken in response to U.S. Bureau of Land Management concerns for the water resources of the Wibaux-Beach area in the event of lignite mining. The objectives of the study were to: (1) Define the stratigraphic sequence within a few hundred feet above and below the minable lignite; (2) define the premining hydrologic and geochemical regime of the Wibaux-Beach deposit area; and (3) describe some of the hydrologic implications of the strip-mining proces… more

Map Showing Altitude of the Top 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 altitude of the top of the Fox Hills-lower Hell Creek aquifer. Other maps show the total thickness (Feltis, 1982a). cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) of the Fox Hills-lower Hell Creek aquifer. These maps are part of a series that describes the … more
