Gold anomalies and magnetometer profile data, Ester Dome area, Fairbanks district, Alaska
D. L. Stevens, Robert B. Forbes, D. B. Hawkins
1969, Open-File Report 69-266
Gold analysis of grab and auger samples of bedrock taken along the new Ester Dome Road reveals that this road cuts several mineralized zones characterized by anomalous concentrations of gold. The results of a magnetometer traverse along this road indicate that the negative magnetic anomalies along the traverse may be...

A system of regional agricultural land use mapping tested against small scale Apollo 9 color infrared photography of the Imperial Valley (California)
Claude W. Johnson, Leonard W. Browden, Robert W. Pease
1969, Open-File Report 71-158
Interpretation results of the small scale ClR photography of the Imperial Valley (California) taken on March 12, 1969 by the Apollo 9 earth orbiting satellite have shown that world wide agricultural land use mapping can be accomplished from satellite ClR imagery if sufficient a priori information is available for the...

Preliminary investigation of gold mineralization in the Pedro Dome-Cleary Summit area, Fairbanks district, Alaska
H.D. Pilkington, R. B. Forbes, D. B. Hawkins, R. M. Chapman, R. C. Swainbank
1969, Open-File Report 69-206
Anomalous gold values in mineralized veins and hydrothermally altered quartz-mica schist in the Pedro Dome-Cleary Summit area of the Fairbanks district suggest the presence of numerous small low- to high-grade lodes. Anomalous concentrations of gold were found to exist in the wall rocks adjacent to mineralized veins. In general, the...

1969, Open-File Report 69-73
The intermediate yield Greeley event, in which a nuclear device was detonated at a depth of 3,990 feet in Pahute Mesa at the Nevada Test Site, caused fracturing in rocks and spalling of rock from cliffs as far as 3 and 8 miles, respectively, from the detonation point....

Preliminary geologic interpretation of aeromagnetic data in the Yakutat district, Alaska
Gordon R. Johnson, George Plafker
1969, Open-File Report 69-134
An aeromagnetic survey covering portions of the Yakutat Feveland region in south-central Alaska was made to delineate concentrations of magnetic minerals possibly associated with heavy mineral placers in beach sands and raised beach ridges. However, the larger magnetic anomalies do not correlate with the beach placers in the surveyed area....
