Map showing free-air gravity anomalies in the southern Beaufort Sea

Free-air gravity anomaly data used in this compilation were obtained from the U.S. Geological Survey; the University of Connecticut Institute of Marine Sciences; and the Earth Physics Branch, Department of Energy, Mines, and Resources, Canada.Bathymetric contours are based primarily upon water-depth data (uncorrected) collected together with the gravity data. Water depths were reported every half

Map showing general availability of ground water in the Kaiparowits coal-basin area, Utah

This is one of a series of maps that describe the geology and related natural resources in the Kaiparowits coal-basin area. This map is based partly on records of water wells, springs, and coal and petroleum exploration holes, partly on unpublished reports of field evaluations of prospective stock-water well sites by personnel of the U.S. Geological Survey, and partly on a 6-day field reconnaissan

Map showing general chemical quality of ground water in the Kaiparowits coal-basin area, Utah

This is one of a series of maps that describe the geology and related natural resources in the Kaiparowits coal-basin area. Chemical analyses of water from about 40 widely scattered springs, 20 coal-exploration holes in the Kaiparowits Plateau, and 7 water wells in the vicinity of the communities of Escalante and Glen Canyon were used to compile this map. All the water samples were from depths of
