Floods of August 1967 in east-central Alaska
Joseph M. Childers, James P. Meckel, Gary S. Anderson
1972, Water Supply Paper 1880-A
East-central Alaska had record floods near Fairbanks following extensive rains of August 8-20, 1967. Precipitation during this period totaled as much as 10 inches, which is close to the average annual precipitation for this area. The most extensive flooding occurred in the White Mountains northeast of Fairbanks and along the...
Maps showing distribution of anomalous amounts of selected elements in stream-sediment and rock samples, Eagle quadrangle, Alaska
1972, Miscellaneous Field Studies Map 356
Maps showing the distribution of anomalous amounts of selected elements found in more than 1,600 stream-sediment and more than 1,500 rock samples have been prepared form results of semiquantitative spectrographic analyses. The samples were collected in the Eagle quadrangle, east-central Alaska, in the summers of 1968, 1969, 1970, and 1971. Figure...
Preliminary geologic map of the northeastern part of the Tanana quadrangle, Alaska
Robert M. Chapman, Warren Yeend
1972, Miscellaneous Field Studies Map 342
Mapping is based on both ground observations and aerial observations from a helicopter, August 11-19 and September 1-5, 1970, and supplemented by interpretation from aerial photographs. Bedrock geology chiefly by R.M. Chapman, and surficial geology chiefly by W.E. Yeend....
Reconnaissance bedrock geologic map of the Chugach Mountains near Anchorage, Alaska
Sandra H. B. Clark
1972, Miscellaneous Field Studies Map 350
The area between Knik and Turnagain Arms east of Anchorage is underlain mostly by rocks that are part of an extensive arcuate belt of thick Mesozoic marine deposits that extend through the Chugach-Kenai-Kodiak Mountains. The two main units in this belt are the Jurassic (?) and Cretaceous Valdez (?) Group...
Reconnaissance geologic map and geochemical analyses of stream-sediment and rock samples of the Anchorage A-6 quadrangle, Alaska
Sandra H. B. Clark, Martha E. Yount
1972, Miscellaneous Field Studies Map 351
A reconnaissance geologic map and analytical data for 70 stream-sediment samples and 34 rock samples for the Anchorage A-6 1:63,360 scale quadrangle are presented in this report, together with a statistical treatment of the geochemical data. The bedrock was mapped and samples collected during the summers of 1969, 1970, and...
Some effects of a heated pipeline on ground-water flow in Alaska
Charles E. Sloan, John D. Bredehoeft
1972, Open-File Report 72-349
The thaw bulb produced by a heated pipeline buried in a stream channel may intercept water confined in shallow unfrozen zones beneath a seasonally frozen layer. Resulting movement of ground water through the thaw bulb might produce quick conditions in the pipeline foundation materials. A digital model showed that such...
Flood surveys along proposed TAPS route, Alaska, July 1971
Joseph M. Childers
1972, Open-File Report 73-45
The U.S. Geological Survey has a threefold responsibility along the proposed route of the Trans-Alaska Pipeline System (TAPS): to investigate possible hydrologic hazards to the pipeline, to investigate possible impacts of the pipeline system on water resources, and to develop a better understanding of Arctic hydrology. One of the major...
