Numerical simulation of three-dimensional groundwater flow near lakes shows that the continuity of the boundary encompassing the local groundwater flow system associated with a lake is the key to understanding the interaction of a lake with the groundwater system. The continuity of the boundary can be determined by the presence...

Pumice layers of set S from Mount St. Helens can be correlated with certain ash beds associated with young flood deposits of the channeled scabland. The correlation points to an age of about 13,000 14C yr B.P. for the last major flood to have crossed the scabland. Until recently, the...

The increasing need for water of good Quality in Columbia County, caused by a steadily increasing population, can be met from the sand-and-gravel and sandstone aquifers. As much as 15 gallons per minute can be obtained from wells almost everywhere. Yields of more than 1,000 gallons per minute are available...

Three seismic reflectors are present throughout the lower Cook Inlet basin and can be correlated with onshore geologic features. The reflections come from unconformities at the base of the Tertiary sequence, at the base of Upper Cretaceous rocks, and near the base of Upper Jurassic strata.A contour map of the...

The area of investigation comprises approximately 540 square miles and lies entirely within the Great Valley section of the Valley and Ridge physiographic province. The Great Valley is underlain chiefly by carbon ate rocks in the south and by shale and graywacke in the north. Most of the carbonate rocks...

The landforms developed on the walls of the Valles Marineris system of chasmas are of three major types, which are locally transitional. The most common type is composed of steep spurs and gullies. The dominant process in the formation or modification of this type appears to be the downslope movement...

Radioactive hot springs issue from a fault zone in crystalline rock of the Boulder batholith at Alhambra, Jefferson County, in southwestern Montana. The discharge contains high concentrations of radon, and the gross alpha activity and the concentration of adium-226 exceed maximum levels recommended by the Environmental Protection Agency for drinking...

The Parowan-Cedar City drainage basin, Iron County, Utah, includes about 1,100 mi2 (square miles)(2,800 km2 [square kilometers])--520 mi2 (1,300 km2) in the Parowan basin and 580 mi2 (1,500 km2) in the Cedar City basin. Parowan and Cedar City Valleys are structural depressions formed by northeast-trending faults. Parowan Valley is essentially...

The Fish Springs Flat area includes about 590 square miles (1,530 square kilometers) in western Utah. Total annual precipitation on the area averages about 7 inches (180 millimeters) and totals about 232,000 acre-feet (286 cubic hectometers). Fish Springs Wash is the major drainage in the area; and, along with numerous...

The central Virgin River basin, Utah, includes about 1,000 square miles (2,600 square kilometers) in the drainage basin of the Virgin River downstream from the Hurricane Cliffs. The Navajo Sandstone of Late Triassic(?) and Jurassic age crops out in 234 square miles (606 square kilometers) of the basin and underlies...

Pervasive secondary biotite-rich mineral assemblages, characteristic of potassic alteration found in the cores of most commercial porphyry copper systems, are associated spatially with a conspicuous color and a geochemical anomaly at La Florida de Nacozari, Sonora. These composite biotite-magnetite assemblages, with or without actinolite, quartz, rutile, sphene, chalcopyrite, and pyrite...

The Dugway Valley-Government Creek area covers about 890 square miles (2,300 square kilometers) in west-central Utah. Total annual precipitation on the area averages about 380,000 acre-feet (470 cubic hectometers). Most streams are ephemeral except for a few in their upper reaches--all are ephemeral below the altitude of about 6,000 feet...

The northern Uinta Basin area covers about 5,200 square miles (13,470 square kilometers) in northeastern Utah and northwestern Colorado. Much of the lowlands are arid to semiarid, but the highest parts of the Uinta Mountains have a humid climate. During 1941-70, the average annual precipitation ranged from less than 8...

Beaver Valley includes 534 square miles in southwestern Utah, in the Basin and Range physiographic province. The project area consists of a valley plain underlain by unconsolidated to partly consolidated material. The valley plain is bounded by mountains that are composed of partly consolidated to consolidated rocks of Pennsylvanian through...
