Both creep and earthflow processes control hillslope erosion over large parts of the Redwood Creek basin. The type of process and displacement rates are largely dependent on underlying bedrock type and precipitation input. Progressive creep with rates ranging from 1.0 to 2.5 mm/a dominates on slopes west of the Grogen...

On August 12-13, 1982, a nearly stationary weather front in the vicinity of Kansas City, MO, produced intense thunderstorms. Excessive rainfall (12.6 inches in Raytown, MO) caused flash flooding during the nighttime and early daylight hours. Four deaths and damages unofficially estimated in excess of $30 million, occurred in the...

Geochemical sampling of the Bunk Robinson Peak and Whitmire Canyon Roadless Areas was completed in the spring of 1980. The purpose of the geochemical sampling was to determine if certain metals, and "pathfinder" elements in heavy-mineral concentrates and stream sediments are enriched beyond normal black-ground amounts. The enrighment of elemental...

Water in Lake Arlington on Village Creek in north-central Texas had volume-weighted average concentrations of less than 240 milligrams per liter of dissolved solids, less than 30 milligrams per liter of dissolved chloride, and less than 40 milligrams per liter of dissolved sulfate between January 29, 1973, and August 20,...

Bed rock in the Stigler area of southeastern Oklahoma consists principally of shale, siltstone, and sandstone of the McAlester, Savanna, and Boggy Formations of Pennsylvanian age. These rocks have been folded to form the Stigler syncline on the north and the Antioch anticline on the south. An area of several...

Bed rock in the Rock Island area of northeastern Le Flore County in southeastern Oklahoma consists of shale, siltstone, and sandstone of the McAlester, Hartshorne, and Atoka Formations of Pennsylvanian age. The area is on the south flank of the Backbone anticline; the rocks dip to the south at 5o-45o....

Water-quality, bottom-material, suspended-sediment, and current-velocity data were collected during November 1981 in Kings Bay and vicinity to provide information on the sources and transport of estuarine sediments. Kings Bay and Cumberland Sound , the site of the Poseidon Submarine Base in southeast Georgia, are experiencing high rates of sediment deposition...

The concepts, structure, theoretical development, and data requirements of the precipitation-runoff modeling system (PRMS) are described. The precipitation-runoff modeling system is a modular-design, deterministic, distributed-parameter modeling system developed to evaluate the impacts of various combinations of precipitation, climate, and land use on streamflow, sediment yields, and general basin hydrology. Basin...

About 93 percent of the Nation 's estimated 30 billion barrels of crude oil in tar sand deposits is in 11 tar-sand deposits in eastern Utah that were chosen for leasing by the Federal government. The Tar Sand Triangle area, which contains about 15 billion barrels of oil, is the...

The U.S. Bureau of Mines and the U.S. Geological Survey have conducted a survey to determine the mineral resource potential of the eastern part (D4757) of the Stansbury Roadless Area, Tooele County, Utah. The results of this survey indicate that a low to moderate potential for copper, lead, and silver...

The Quaternary Geologic Map of the Chicago 4 degree x 6 degree Quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during...
