A proposed streamflow-data program in Alaska
J.M. Childers
1970, Open-File Report 70-62
The streamflow-data program in Alaska was analyzed to design a better data network. The analysis included (1) definition of the goals of the streamflow-data program, (2) evaluation of the available data to see which goals have already been achieved, and (3) consideration and recommendation of future programs to achieve the...
Morphology, sedimentation, and seismic characteristics of an arctic beach, Nome, Alaska - with economic significances
H. Gary Greene
1970, Open-File Report 70-142
Arctic beaches exhibit characteristics that do not occur on beaches in more temperate zones. In the summer of 1967 morphological, sedimentological, and seismic refraction studies were made on an arctic beach near Nome, Alaska, in order to better define these distinguishing characteristics.Several distinct microrelief structures are developed during ice break-up...
A review of water resources of the Umiat area, northern Alaska
John R. Williams
1970, Circular 636
Surface-water supplies from the Colville River, small tributary creeks, and lakes are abundant in summer but limited in winter by low or zero flow in streams and thick ice cover on lakes. Fresh ground water occurs in unfrozen zones in alluvium and in the upper part of bedrock beneath the...
Effects of the earthquake of March 27, 1964, on the Alaska Railroad
David S. McCulloch, Manuel G. Bonilla
1970, Professional Paper 545-D
In the 1964 Alaska earthquake, the federally owned Alaska Railroad sustained damage of more than $35 million: 54 percent of the cost for port facilities; 25 percent, roadbed and track; 9 percent, buildings and utilities; 7 percent, bridges and culverts; and 5 percent, landslide removal. Principal causes of damage were:...
Analysis of Shublik Formation rocks from Mt. Michelson quadrangle, Alaska
Robert L. Detterman
1970, Open-File Report 70-101
Analysis of 88 samples from the Shublik formation on Fire Creek, Mt. Michelson Quadrangle, Alaska, are presented in tabular form. The results include the determination of elements by semiquantitative spectrographic analysis, phosphate by X-ray fluorescence, carbon dioxide by acid decomposable carbonate, total carbon by induction furnace, carbonate carbon by conversion...
The Alaska earthquake, March 27, 1964: Lessons and conclusions
Edwin B. Eckel
1970, Professional Paper 546
One of the greatest earthquakes of all time struck south-central Alaska on March 27, 1964. Strong motion lasted longer than for most recorded earthquakes, and more land surface was dislocated, vertically and horizontally, than by any known previous temblor. Never before were so many effects on earth processes and on...
Paleozoic and Precambrian rocks of Alaska and their role in its structural evolution
Michael Churkin Jr.
1970, Open-File Report 70-64
Acknowledging that there are large gaps in the knowledge of the geology of Alaska, the following threefold subdivision of Alaska into Paleozoic tectonic elements is proposed: Southern Alaska--the Alaska Range and farther south--is the northern end of the Paleozoic Cordilleran geosyncline that rims the eastern Pacific. Northern Alaska--the northeastern Brooks...
Petroleum possibilities of the Yukon-Koyukuk Province, Alaska
William Wallace Patton Jr.
1970, Open-File Report 70-257
The recent discovery of major oil resources on Alaska's North Slope has rekindled interest in the petroleum possibilities of the Yukon-Koyukuk province, a vast tract of Cretaceous rocks stretching along the west coast of Alaska from the Brooks Range to the Yukon delta. Attention was first focused on this region...
