Maps

After the end of the Civil War in 1865, families longed for fresh starts. This desire fueled new studies of the west. Reconnaissance missions by Hayden and Powell would ultimately lead to the establishment of the U.S. Geological Survey in 1879. From that time forward, mapping topography, geology, mineral resources, and water became then, and is today, an integral part of the USGS mission.

Ground-water resources of the southern Wasatch Front area, Utah

This is one of a series of map reports compiled by the USGS and UGS describing the geology and related natural resources and hazards of the densely populated Wasatch Front of Utah. This report defines in a non-technical format the occurrence, availability, and quality of ground water in the southern Wasatch Front area and guides readers to sources of more detailed information about the resource.

Ground-water resources of the central Wasatch Front area, Utah

This is one of a series of map reports compiled by the USGS and UGS describing the geology and related natural resources and hazards of the densely populated Wasatch Front of Utah. This report defines in a non-technical format the occurrence, availability, and quality of ground water in the central Wasatch Front area and guides readers to sources of more detailed information about the resource.

Maps of estimated nitrate and arsenic concentrations in basin-fill aquifers of the southwestern United States

Human-health concerns and economic considerations associated with meeting drinking-water standards motivated a study of the vulnerability of basin-fill aquifers to nitrate contamination and arsenic enrichment in the southwestern United States. Statistical models were developed by using the random forest classifier algorithm to predict concentrations of nitrate and arsenic across a model grid repre

Regional potentiometric-surface map of the Great Basin carbonate and alluvial aquifer system in Snake Valley and surrounding areas, Juab, Millard, and Beaver Counties, Utah, and White Pine and Lincoln Counties, Nevada

Water-level measurements from 190 wells were used to develop a potentiometric-surface map of the east-central portion of the regional Great Basin carbonate and alluvial aquifer system in and around Snake Valley, eastern Nevada and western Utah. The map area covers approximately 9,000 square miles in Juab, Millard, and Beaver Counties, Utah, and White Pine and Lincoln Counties, Nevada. Recent (2007

Net-infiltration map of the Navajo Sandstone outcrop area in western Washington County, Utah

As populations grow in the arid southwestern United States and desert bedrock aquifers are increasingly targeted for future development, understanding and quantifying the spatial variability of net infiltration and recharge becomes critically important for inventorying groundwater resources and mapping contamination vulnerability. A Geographic Information System (GIS)-based model utilizing readily

Bathymetric map of the north part of Great Salt Lake, Utah, 2006

The U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Forestry, Fire, and State Lands, collected bathymetric data for the north part of Great Salt Lake during the spring and early summer of 2006 using a single beam, high-definition fathometer and real-time differential global positioning system. Approximately 5.2 million depth readings were collected

Bathymetric map of the south part of Great Salt Lake, Utah, 2005

The U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Wildlife Resources, collected bathymetric data for the south part of Great Salt Lake during 2002–04 using a single beam, high-definition fathometer and real-time differential global positioning system. Approximately 7.6 million depth readings were collected along more than 1,050 miles of survey tr

Channel migration of the White River in the eastern Uinta Basin, Utah and Colorado

The White River is the largest stream in the southeastern part of the Uinta Basin in Utah and Colorado. This map shows the changes that have occurred in the location of the main channel of the river from 1936 to 1974. The map indicated that certain reaches of the river are subject to different rates of channel migration. Also shown is the boundary of the flood plain, which is mapped at the point o

Vegetation map of the southeastern Uinta Basin, Utah and Colorado

This map has been prepared by the U.S. Geological Survey as part of a hydrologic investigation of the southeastern Uinta Basin in cooperation with the Utah State Engineer and the U.S. Bureau of Land Management. The map defines the extent of dominant types of vegetation within the study area prior to proposed oil-shale development. The information presented will be helpful for estimating runoff and
