Earthquakes, October-November 1976
W. J. Person
1977, Earthquake Information Bulletin (USGS) (9) 32-36
October brought two damaging earthquakes to Ecuador and New Guinea. The Ecuador earthquake, although only magnitude 5.5, caused casualties and damage. The new Guinea earthquake, a major quake, caused a loss of life and damage. Two major earthquakes were experienced during November, in eastern Turkey on November 24 and in...
Heavy-mineral variability in bottom sediments of the lower Chesapeake Bay, Virginia
F. Firek, G. L. Shideler, P. Fleischer
1977, Marine Geology (23) 217-235
Heavy minerals in bottom-sediment samples of the lower Chesapeake Bay show distribution patterns and interrelationships that denote characteristic mineral suites associated with defined geographic provinces. The Baymouth province has a garnet-hornblende-pyroxene suite, which is largely attributed to the influx of littoral and shelf sediments; the Eastern Shore province has a...
Earthquake history of Tennessee
C. A. von Hake
1977, Earthquake Information Bulletin (USGS) (9) 37-39
The western part of the State was shaken strongly by the New Madrid, Mo., earthquakes of 1811-12 and by earthquakes in 1843 and 1895. The area has also experienced minor shocks. Additional activity has occurred in the eastern part of the State, near the North Carolina border. Forty shocks of...
Modeling chloride movement in the alluvial aquifer at the Rocky Mountain Arsenal, Colorado
Leonard F. Konikow
1977, Water Supply Paper 2044
A solute-transport model that can be used to predict the movement of dissolved chemicals in flowing ground water was applied to a problem of ground-water contamination at the Rocky Mountain Arsenal, near Denver, Colo. The model couples a finite-difference solution to the ground-water flow equation with the method-of-characteristics solution to...

W. B. Scott
1977, Water-Resources Investigations Report 76-119
Subsurface geophysical logs were correlated with logs of drill cuttings to determine the permeability of selected zones of the shallow aquifer, Palm Beach County, Fla. The hydraulic conductivity of the aquifer is estimated to range from 1 to 130 feet per day, based on lithology and physical properties. The yield...
Ground-water resources and geology of Walworth County, Wisconsin
Ronald G. Borman
1976, Wisconsin Geological & Natural History Survey Information Circular 34
Population growth in Walworth County, Wisconsin, requires an increasing amount of ground water. Good quality water is available from the sand-and gravel, Niagara, Galena-Platteville, and sandstone aquifers in the county. As much as 15 gallons per minute (0.95 liters per second) can be obtained from individual wells almost everywhere in...

Digital-model analysis of the effects of water-use alternatives on spring discharges Gooding and Jerome Counties, Idaho
Joe A. Moreland
1976, Water Information Bulletin 42
Springs discharging from the Snake Plain aquifer contribute approximately 6,000 cubic feet per second (170 cubic metres per second) to flow in the Snake River between Milner and King Hill. Before irrigation began on the Snake River Plain north and east of the springs, total spring discharge was about 4,200...

1976, Technical Publication 50
This report describes the study of the Rocky Point Canal system in the vicinity of Duchesne and the Grey Mountain-Pleasant Valley Canal system between Duchesne and Myton, in the Uinta Basin, Duchesne County, Utah. The Rocky Point Canal diverts from the left bank of the Duchesne River about 4 mi...
Beacon Hill end moraine, Boston: new explanation of an important urban feature
Clifford A. Kaye
Donald R. Coates, editor(s)
1976, Book chapter, Urban Gomorphology (Geological Society of America, Special Paper 174)
The usefulness of geology to engineers is in direct proportion to how well it helps us predict the subsurface; these predictions, in turn, depend on our knowledge of the geomorphic processes that molded the terrain. The uncertainties of interpretation are particularly great in glaciated terrain because our understanding of both...

The Raft River valley, near the boundary of the Snake River plain with the Basin and Range province, is a north-trending late Cenozoic downwarp bounded by faults on the west, south, and east. Pleistocene alluvium and Miocene-Pliocene tuffaceous sediments, conglomerate, and felsic volcanic rocks aggregate 2 km in thickness. Large...
Tectonic framework of petroliferous rocks in Alaska: hydrocarbons
Arthur Grantz, C.E. Kirschner

Alaska, which contains about 28% of the land and continental shelf of the United States, is estimated by the U.S. Geological Survey to contain about one third of the nation's undiscovered oil and about one sixth of its undiscovered natural gas. The Survey estimates that fields discovered in Alaska through...

Incidence of lead shot in canvasbacks
Matthew C. Perry
1976, Book chapter, Transactions of the Canvasback Workshop : April 6-7, 1976, Ramada Inn, Jamestown, North Dakota
During 1975 and 1976, 2,544 canvasbacks (Aythya valisineria) from North Dakota, Wisconsin, Illinois, and Maryland were flouroscoped to determine the incidence of body shot. A significant increase from west to east was detected in the incidence of shot for immatures from the four states. The incidence of shot...
