Ronald L. Soroos, Charles J. Ewart
1979, Open-File Report 79-1542
Increasing demand for freshwater in Hawaii has placed heavy stress on many of the State 's basal aquifer systems. The most heavily stressed of these systems is the Pearl Harbor on Oahu. The Pearl Harbor basal aquifer supplies as much as 277 million gallons per day. Since early in this...
In situ bulk density and porosity estimates from borehole gravity data in limestones of the Madison Group; test well No. 1, Crook County, Wyoming
Bruce A. Kososki, Stephen L. Robbins
1979, Open-File Report 79-1514
In 1975 the U.S. Geological Survey, in cooperation with the Old West Regional Commission, prepared a plan of study (U.S. Geological Survey, 1975) for evaluating the water-supply potential of limestone of the Madison Group and associated rocks. To obtain better subsurface hydrologic and geologic information it was recognized that Madison...
HYPOELLIPSE: A computer program for determining local earthquake hypocentral parameters, magnitude, and first motion pattern
John C. Lahr
1979, Open-File Report 79-431
HYPOELLIPSE is a computer program for determining the hypocenters of local or near regional earthquakes and for each event the ellipsoid which encloses the one standard deviation region. Traveltimes are determined from a horizontally layered crustal structure or from a linear increase of velocity with depth. Arrival times for the...

Hydrologic data, 1974-77, Stovepipe Wells Hotel area, Death Valley National Monument, Inyo County, California
Charles Edwin Lamb, D.J. Downing
1979, Open-File Report 79-203
Ground-water levels in most wells did not change significantly from 1974 to 1977 in the Stovepipe Wells Hotel area. The average water-level decline was less than 0.10 foot between August 1974 and August 1977 in 10 observation wells. Water-level contours show a depression centered on the two pumping wells, but...

Downhole pumps for water sampling in small diameter wells
F. C. Koopman
1979, Open-File Report 79-1264
The relatively high cost and difficulty in locating a source of pumps for use in obtaining ground-water samples from small-diameter wells has demonstrated a need for this report. Criteria for selection of a pump and pumping equipment to meet specific requirements has been tabulated to assist field personnel in making...
Surface-water features in Osceola County and adjacent areas, Florida
G.H. Hughes, James M. Frazee Jr.
1979, Open-File Report 79-1289
The western two-thirds of Osceola County, Fla., drains southward by way of the Kissimmee River and its tributaries; the eastern one-third drains eastward to the St. Johns River or to marshy areas that make up part of the headwaters of the St. Johns River. About 15 percent of the county...

Discrimination of alteration in the Crooks Gap, Wyoming, uranium district using laboratory and Landsat spectral reflectance data
Timothy E. Townsend
1979, Open-File Report 79-765
The Crooks Gap area is a major uranium producing district in south-central Wyoming. Uranium occurs there as roll-type deposits in Tertiary sandstones. Alteration of the host sandstones related to the formation of the uranium deposits, is marked at the surface by a pronounced red coloration, which has long been used...
Knik Glacier, Alaska, May 1979 monument and glacier survey
Dennis C. Trabant, L.R. Mayo
1979, Open-File Report 80-48
From 1915, or earlier, to 1966, with the exception of 1963, Knik Glacier annually formed and released Lake George, the largest glacier-dammed lake in Alaska. Eleven geodetically controlled survey stations were defined in the basin, and 22 glacier surface altitudes were measured. This is the first effort in a continuing...
