1975, Miscellaneous Field Studies Map 670-D
In the Fairbanks area, the effects of development on the geologic environment must be considered in determining proper land use. Persons concerned with the land, especially land planners, developers, public officials, engineers, architects, financial advisors, and educators, must be aware of recognizable geologic features that may prove hazardous; only then...

Map showing ground water conditions in the Fairbanks D-1 SW quadrangle, Alaska
Troy L. Pewe, John W. Bell
1975, Miscellaneous Field Studies Map 671-B
The primary controlling factors determining ground-water conditions in the Fairbanks D-1 SW quadrangle are (1) topographic position, (2) water-bearing characteristics of the rocks, and (3) distribution of permafrost. These interrelated factors generally limit the conditions in any particular area. Basic data from the geologic map of the Fairbanks D-1 SW quadrangle...

Crustal movement investigations
James C. Savage
1975, Reviews of Geophysics (13) 263-265
Studies of horizontal crustal movement using conventional geodetic methods have been considerably expanded in the quadrennium 1971–1974. The basic fault monitor Geodimeter network now covers most of the major faults in California as well as the zone of faulting that extends into Nevada. Isolated Geodimeter networks in seismic areas of...
Progressive metamorphism of schists recovered from a deep drill hole near Fairbanks, Alaska
Robert B. Forbes, Florence R. Weber
1975, Journal of Research of the U.S. Geological Survey (3) 647-657
In 1965, a deep test hole drilled near Eielson Air Force Base, Fairbanks district, Alaska, penetrated 9,774 ft (2,979.1 m) into schists of the metamorphic complex of the Yukon-Tanana Upland. Cores recovered from the test hole show that the section is dominated by calc-magnesian rocks with subordinate pelitic schists. Pelitic...

Samples of aquatic organisms and water were collected upstream and downstream from leaks and spills of arctic diesel fuel oil into Happy Valley Creek near Sagwon, Alaska. All groups of benthic invertebrates were reduced in abundance at the downstream boundary of the spill area, whereas invertebrates at an upstream site...
Geologic setting and chemical characteristics of hot springs in west-central Alaska

Repeated site surveys and aerial photographs at 26 stream crossings along the trans-Alaska pipeline system (TAPS) route during the period 1969-74 provide chronologie records of channel changes that predate pipeline-related construction at the sites. The 1974 surveys and photographs show some of the channel changes wrought by construction of the...

Reconnaissance sampling of surface and subsurface sediment to a maximum depth of 80 m below the sea floor shows that typical values of 0.03 p.p.m. and anomalies of 0.2-1.3 p.p.m. mercury have been present in northeastern Bering Sea since Early Pliocene time. Values are highest in modern beach (maximum 1.3...
