Summary of reconnaissance for radioactive deposits in Alaska, 1945-1954, and an appraisal of Alaskan uranium possibilities
Helmuth Wedow Jr.
1956, Trace Elements Investigations 577
In the period 1945-1954 over 100 investigations for radioactive source materials were made in Alaska. The nature of these investigations ranged from field examinations of individual prospects or the laboratory analysis of significantly radioactive samples submitted by prospectors to reconnaissance studies of large districts. In this period no deposits of...
Radiometric traverse along the Yukon River from Fort Yukon to Ruby, Alaska, 1949
Max G. White, John M. Stevens, John J. Matzko
1956, Trace Elements Memorandum 357
In 1949, a radiometric traverse was made of rocks exposed along the banks of and near the Yukon River about Fort Yukon to Ruby, Alaska. Granitic rocks of Tertiary age and of Devonian or Carboniferous age and sandstone beds of Cretaceous age gave the highest readings obtained in the...
Preliminary report on the potential waterpower of Grant, Ptarmigan, Cooper and Crescent lakes on the Kenai Peninsula, near Seward, Alaska
Arthur Johnson
1955, Open-File Report 55-74
Grant, Ptarmigan, Cooper, and Crescent Lakes, located in the Kenai Mountains in the upper portion of the Kenai River Basin, approximately 25 miles to the north of Seward, present favorable opportunities for the development of waterpower. Grant and Ptarmigan Lakes can be made readily accessible by roads from the Seward-Anchorage...
Preliminary geologic map and structure sections of the Shaktolik River area, Alaska
William W. Patton Jr., Robert S. Bickel
1955, Open-File Report 55-134
The U.S. Geological Survey began stratigraphic and structural studies in the southern half of the Koyukuk Cretaceous basin in 1954. During June 1954, the Shaktolik River was traversed by boat from near the confluence of Brass Pan Creek to Norton Sound. All cutback exposures along the river were examined and,...
Photogeologic procedures in geologic interpretation and mapping
Richard G. Ray
1955, Open-File Report 55-144
In the past few years increasing use has been made of aerial photographs for geologic interpretation and mapping within the U.S. Geological Survey. As a specialized technique in interpretation and mapping, however, photogeologic procedures were extensively used (1947-1953) in the Survey's geologic mapping of Naval Petroleum Reserve No. 4 in...
Occurrence of diatomaceous earth near Kenai, Alaska
George Plafker
1955, Open-File Report 55-139
Diatomaceous earth occurs in post-glacial lake deposits exposed along the shore of Cook Inlet north of the village of Kenai, Alaska. Diatomaceous earth is an unconsolidated earthy deposit formed by accumulation of the minute siliceous tests (skeletons) of diatoms, a type of algae. Diatomaceous earth is sometimes referred to...
