Refractory flint clay and semiflint clay layers, totaling as much as 7% feet in thickness, occur in the lower part of the Allegheny Formation of Pennsylvanian age in north-central Randolph County, W.Va. The deposit seems to be a lens in a widespread bed of plastic clay and may underlie an area of 1-2 square miles. Refractory tests of three samples indicate a pyrometric cone equivalent of cone 30-3

This report is the result of a cooperative agreement between the city of Cedar Rapids and the U.S. Geological Survey that provides for the collection of hydrologic data by the Geologic Survey on small streams in and near the city. The city furnished the large-scale topographic map showing a stream reference line marked off in 100-foot stations and a part of the data on valley cross sections used i

Detailed mapping has shown that the carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania, can be divided into 14 rock-stratigraphic units. These units are defined primarily by their relative proportions of limestone and dolomite. The oldest units, the Vintage, Kinzers, and Ledger Formations of Cambrian age, and the Conestoga Limestone of Ordovician age are retai

This report is the fifth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series are prepared cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources and are designed to provide data to enable interested parties such as legislators, administrators, and planners to keep abreast of changing ground-water conditions.This report,

During the past 60 years, the characteristics of fluvial sediment in many streams in the Unites States have been studied by Federal agencies. The purpose of this report is to present available data – both published and unpublished – on fluvial sediment in Utah for the period 1905-65. (See figs. 1 and 2)

The investigation of dissolved-mineral inflow to Great Salt Lake during the water years 1960, 1961, and 1964 was conducted during conditions of streamflow that were representative of the lowest and the average recorded during the water years 1934-64. The study conducted during the 1960 and 1961 water years was limited to defining surface-water inflow at sites close to the lakeshore, as well as at

This report provides long-term data on streamflow at selected short-term gaging stations in Utah. The records of streamflow at the short-term or secondary gaging stations are extended on the basis of a graphical correlation with concurrent records at long-term or primary gaging stations. The data presented consist of records of runoff at the short-term stations summarized on a monthly and yearly b

The Sevier and Beaver River systems are the two major river systems in the Sevier Lake basin in Utah. This report contains an analysis of reconnaissance data collected during the 1964 water year regarding the quality of water in these rivers and their tributaries. The purpose of the reconnaissance was to obtain needed water-quality information for the basin. Corollary purposes were to (1) determin

This report is the second in a series by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, which describes the water resources of the western basins of Utah. Its purpose is to present available hydrologic data on Skull Valley, to provide an evaluation of the potential water-resource development of the valley, and to identify needed s

In 1957, the National Park Service requested that the U. S. Geological Survey determine the quality and quantity of available ground water at selected sites within the Cape Hatteras National Seashore Recreational Area. A series of reports, Ground-Water Supply of Cape Hatteras National Seashore Recreational Area" by P. M. Brown (1960), "Ground-Water Supply of Cape Hatteras National Seashore Recreat

Eddy and Foster Counties are in east-central North Dakota, high on the eastern flank of the Williston Basin. They are underlain by 3200 to 4300 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The uppermost formation, the Cretaceous Pierre Shale, lies directly beneath the glacial drift and crops out in the valleys of the James and Sheyenne Rivers. Glacial drift that covers the ent
