Limnological investigation of six lakes in southeast Alaska
George A. McCoy, William W. Wiggins, Artwin E. Schmidt
1976, Water-Resources Investigations Report 76-122
Limnological data were collected from six lakes in southeast Alaska in 1974. The data include concentrations of major inorganic constituents, nutrients, selected trace metals, total organic carbon, and chlorophyll. Vertical profiles of specific conductance, temperature, dissolved-oxygen saturation, and pH were drawn. With the exception of Redoubt Lake, all of the...

A preliminary evaluation of selected earthquake-related geologic hazards in the Kenai Lowland, Alaska
Russell G. Tysdal
1976, Open-File Report 76-270
Several major faults exist beneath the Kenai Lowland, and others may be inferred. No surface evidence was found to indicate that any of the faults have been active in Holocene time. The sparse shallow seismicity thus far recorded does not correlate with known faults, nor does it define linear trends...

George Plafker, Warren O. Addicott
1976, Open-File Report 76-84
Perhaps the world's longest and most complete onshore sedimentary record of late Cenozoic glaciation is preserved in the Gulf of Alaska Tertiary province that extends 800 km along the coast of southern Alaska. The Yakataga Formation, with an aggregate outcrop thickness of about 5,000 m, is characterized by variable amounts...

Miles L. Silberman, David Moody Hopkins
1976, Open-File Report 76-733
St. George Island is one of the Pribilof Islands which lie between 56°35' and 57°11' N. lat. in the Bering Sea, 350 km north of the Aleutian chain. The islands are situated near the margin of the continental platform that underlies most of the northern half of the Bering Sea...
Platinum deposits of the Goodnews Bay district, Alaska
John Beaver Mertie Jr.
1976, Professional Paper 938
Platinum placers were discovered in 1926 in a small area south of Goodnews Bay, in southwestern Alaska. Beginning in 1927, the placers were worked for 7 years by small-scale mining methods; in later years dragline excavators and a dredge were utilized. These deposits are important, not only because they are...
Hard rock uranium potential in Alaska
Thomas P. Miller
1976, Open-File Report 76-246
Discussing the potential of "hardrock" (i.e., non-sedimentary type) uranium deposits in a 586,000 mi2 portion of the North America Cordillera is a difficult task compounded by the fact that the remoteness of much of the region and the logistical difficulties have resulted in only reconnaissance geologic information being available for...
Geohydrology of the lowland lakes area, Anchorage, Alaska
Chester Zenone
1976, Water-Resources Investigations Report 76-22
Unconsolidated deposits, chiefly of glacial origin, make up the surficial geologic materials in the Anchorage lowland lakes area , the western part of the Anchorage glacial outwash plain. Postglacial accumulation of peat, commonly 5 to 10 feet thick, and the presence of ground water at or very near the surface...
Preliminary report on uranium-, thorium-, and rare-earth-bearing rocks near Golovin, Alaska
Thomas P. Miller, Raymond L. Elliott, Warren I. Finch, Robert A. Brooks
1976, Open-File Report 76-710
Uranium-, thorium-, and rare-earth bearing rocks were found by a U.S. Geological Survey field party 15 miles northeast of Golovin, Alaska, in the southeastern Seward Peninsula (fig. 1) in June 1976. The mineralized areas occur in syenite and appear to be concentrated along the margins of alkaline dikes, with allanite...
Submarine faults and slides that disrupt surficial sedimentary units, northern Gulf of Alaska
Paul R. Carlson
1976, Open-File Report 76-294
Faults and submarine slides or slumps of Quaternary age are potential environmental hazards on the outer continental shelf (OCS) of the northern Gulf of Alaska. Most of the faults that approach or reach the seafloor cut strata that may be equivalent to the upper Yakataga Formation (Pliocene-Pleistocene). Along several faults...

Textural and mineralogical study of sandstones from the onshore Gulf of Alaska Tertiary Province, southern Alaska
Gary R. Winkler, Hugh McLean, George Plafker
1976, Open-File Report 76-198
Petrographic examination of 74 outcrop samples of Paleocene through Pliocene age from the onshore Gulf of Alaska Tertiary Province indicates that sandstones of the province characteristically are texturally immature and mineralogically unstable. Diagenetic alteration of framework grains throughout the stratigraphic sequence has produced widespread zeolite cement or phyllosilicate grain coatings...
Preliminary space image lineament maps of Alaska
Ernest Hartwell Lathram, Robert G.H. Raynolds
1976, Open-File Report 76-341
Examination of images from Nimbus, NOAA and Landsat satellites has revealed a series of lineaments in the earth's surface in Alaska 1000 km or more in length (fig. 1). These lineaments occur as alinements of surface geologic structures, linear valleys or ridges, and linear changes in tonal contrast marking differences...
Channel erosion surveys along TAPS route, Alaska, 1976
Paul F. Doyle, Joseph M. Childers

Channel surveys were made along the TAPS route during 1976 at the same 27 sites that were surveyed in 1975. One additional site was put under surveillance in 1976. Except for construction changes wrought by installation of the pipeline, most of the sites surveyed showed very little change since the...
