The purpose of this investigation was to correlate the results of past studies in parts of five developed basins in southwestern Utah and to give a unified concept of ground-water conditions in the entire area. The area of investigation comprises about 3,600 square miles in Washington, Iron, Beaver, and Millard...

This progress report presents the results of a test-well drilling program undertaken by the Antelope Valley-East Kern Water Agency and the U.S. Geological Survey in the western part of Antelope Valley, Calif. Eight test wells were drilled by the rotary method, and electric and lithologic logs were made of each...

Hydrologic data collected during the climatically near-average 6-year period of inventory 1957-62 provide the basis for making estimates of supply to and demand from the Lompoc subarea of the Santa Ynez River basin and changes in the quantity of water stored in the deposits of the basin. The hydrologic inventory...

The High Plains of Colorado includes all or part of 11 counties and has an area of about 9,500 square miles. The land surface slopes eastward and in most areas is gently rolling owing to erosion by ephemeral streams. The Ogallala Formation, of Pliocene age, is the principal aquifer. In...

The probable magnitude of floods of any recurrence interval between 1.1 and 50 years for any stream in the Great Basin can be determined by methods presented in this report.The Great Basin comprises nearly all of Nevada, western Utah, eastern California, and parts of Idaho, Oregon, and Wyoming. The physiography...

A cooperative investigation to determine the geology of the Weber Delta district, with emphasis on the occurrence and chemical quality of ground water, was made by the U.S. Geological Survey and the U.S. Bureau of Reclamation with the later assistance of the Utah State Engineer in the final preparation of...

The Aurora area is a glaciated upland of drift-mantled slopes, channels, swamps, and glacial-lake plains. It covers about 24 square miles of the eastern part of the Mesabi Iron Range in northeastern Minnesota. A deep narrow channel along the Embarrass River, the principal outlet of a former large glacial lake...

The Alaska earthquake of March 27, 1964, caused widespread geomorphic changes in the Martin-Bering Rivers area-900 square miles of uninhabited mountains, alluvial flatlands, and marshes north of the Gulf of Alaska, and east of the Copper River. This area is at lat 60°30’ N. and long 144°22’ W., 32 miles...

Sedimentary and volcanic rocks of Mesozoic and early Tertiary age form a roughly arcuate pattern in and around Prince William Sound, the epicentral region of the Alaska earthquake of 1964. These rocks include the Valdez Group, a predominantly slate and graywacke sequence of Jurassic and Cretaceous age, and the Orca...

The upper Capibaribe basin is the western three-fourths, approximately, of the valley of the river that empties into the Atlantic Ocean at Recife, the capital of the State of Pernambuco, Brazil. It is the part of the drainage basin that is within the Drought Polygon of northeast Brazil, and it...

Kodiak Island and the nearby islands constitute a mountainous landmass with an aggregate area of 4,900 square miles that lies at the western border of the Gulf of Alaska and from 20 to 40 miles off the Alaskan mainland. Igneous and metamorphic rocks underlie most of the area except for...

The part of the Atlantic Coastal Plain that extends from New Jersey through Virginia was selected as a suitable field model in which to study the relationships between geology, hydrology, and chemical character of ground water. The ground-water flow pattern is the principal hydrologic control on the chemical character of...

This fundamental element, whether profuse or scarce, rules the life and character of Florida's great park. But water, like living space, is a resource that civilization demands in ever increasing quantities. Examined here are the economics of water use by Florida's east coast cities and its effects on Everglades ecology....

A study of 23,000 miles of total intensity aeromagnetic profiles in the central Arctic has been made by the U. S. Geological Survey and the U. S. Coast and Geodetic Survey. The profiles were flown at 20,000 feet above sea level and cover approximately 1,350,000 square miles of the Arctic Ocean between the North Pole...

Analyses of lead isotopes in galena in carbonate rock ore deposits collected from several mineralized districts in the Central and Eastern Interior of the United States support previous studies in establishing that the galena is anomalously radiogenic ("J"type")- This study, using care-fully selected samples to test some géologie relationships, shows region-wide and distrietwide systematic variations in isotope...

The average composition of the continental crust is more mafic than hitherto supposed. The conterminous United States can be divided, on the basis of seismic structure, into ten regions. The seven western and the three eastern regions can be termed western and eastern...

During the 10 to 15 years investigators from Europe and eastern United States have reported fish diseases of virus etiology. Rucker et al. in 1953 were the first to report a disease of possible virus origin in fish in the western United States. Since then many workers in the western...

Otter Creek basin comprises 287 square miles in Kiowa, Comanche, and Tillman Counties. The basin is not typical of southwestern Oklahoma in that it includes massive mountains and scattered knobs and peaks of the Wichita Mountains. Alluvium covers much of the southern half of the basin but is restricted to...
