Maps

This is one of a series of maps that describe the geology and related natural resources in the Kaiparowits coal-basin area. Streamflow records used to compile this map and the accompanying table were collected by the U.S. Geological Survey in cooperation with the Utah State Engineer and the Utah Department of Transportation. The principal runoff-producing areas were delineated from a...

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 This map is based partly on records of water wells, springs, and coal and petroleum exploration holes, partly on unpublished reports of field evaluations of prospective stock-water well sites by personnel of the U.S. Geological Survey, and partly on a 6-day field

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...

In the past man has built on land that might be covered by floodwaters, with little consideration of the consequences. The result has been disastrous to those in the path of floodwaters and has cost the loss of thousands of lives and untold billions of dollars in property damage in the United States. Salt Lake County, of which the Sugar House quadrangle is a part, has had many floods in...

This map was first published as a printed edition in 1974. The geologic data have now been captured digitally and are presented here along with images of the printed map sheets. The map encompasses the area of four 7.5-minute quadrangles between 39º15' and 39º 30'N and 106º15' and 106º30'W in the Sawatch and Gore mountain ranges, and upper part of the Arkansas River drainage in central...

The Navajo and Hopi Indian reservations are located mainly in northeastern Arizona, although the Navajo Indian reservation extends into northwestern New Mexico and southeastern Utah (see location map). The area of this report coincides with the areas of the Navajo and Hopi Indian reservations except in part of New Mexico, where the areas was extended eastward to longitude 108° and...

This map provides information on the location and distribution of three general types of geologic materials in part of Salt Lake County, including the southeastern part of Salt Lake City, Utah. These materials have different physical properties that are pertinent to comprehensive planning and zoning, land-use studies, and engineering usage. The map should be of use in preliminary studies...

The concentration of dissolved solids in water from the principal aquifer ranges from about 100 mg/l (milligrams per liter) to as much as 800 mg/l. Water containing the least dissolved solids occurs in an arcuate, mile-wide band along the southern border of the Sugar House quadrangle. Water containing the most dissolved solids occurs in a 3½-mile–wide band in the northern part of the...

The depth to ground water in shallow aquifers in the Sugar Horse quadrangle ranges from zero in areas of springs and seeps to more than 10 feet beneath most of the area shown on the map. The depth to water differs from place to place because of irregular topography, and the varying capability of different rock materials to transmit water. Ground water also occurs under unconfined and...

The potentiometric surface is an imaginary surface representing the static head of ground water and defined by the levels to which ground water would rise in tightly cased wells. The potentiometric surface of the principal aquifer within the area of the Sugar House quadrangle ranges from about 20 feet above, to as much as 500 feet below land surface as is shown on the map. The principal...

The depth to the top of the principal aquifer in the Sugar House quadrangle ranges from about 50 feet to more than 400 feet below land surface. The principal aquifer supplied about 4 percent, or 9,000 acre-feet, of the municipal and industrial water used annually in Salt Lake County curing 1964-68. The least depths occur in topographically low areas of the Jordan Valley, such as near...

Saturated Quaternary deposits in the Sugar Horse quadrangle supply significant quantities of water to wells from which water is withdrawn for domestic, municipal, industrial, and irrigation uses. The deposits consist of clay, silt, sand, and gravel; individual beds range from a few inches to several tens of feet thick. The principal aquifer, which is almost completely within the...
