Gravity survey and regional geology of the Prince William Sound epicentral region, Alaska
J. E. Case, D.F. Barnes, George Plafker, S. L. Robbins
1966, Professional Paper 543-C
Sedimentary and volcanic rocks of Mesozoic and early Tertiary age form a roughly arcuate pattern in and around Prince William Sound, the epicentral region of the Alaska earthquake of 1964. These rocks include the Valdez Group, a predominantly slate and graywacke sequence of Jurassic and Cretaceous age, and the Orca...
The Alaska earthquake, March 27, 1964: Field investigations and reconstruction effort
Wallace R. Hansen, Edwin B. Eckel, William E. Schaem, Robert E. Lyle, Warren George, Genie Chance
1966, Professional Paper 541
One of the greatest geotectonic events of our time occurred in southern Alaska late in the afternoon of March 27, 1964. Beneath a leaden sky, the chill of evening was just settling over the Alaskan countryside. Light snow was falling on some communities. It was Good Friday, schools were closed,...
Magnetic data on the structure of the central Arctic Region
E. R. King, I. Zietz, L.R. Alldredge
1966, Geological Society of America Bulletin (77) 619-646
A study of 23,000 miles of total intensity aeromagnetic profiles in the central Arctic has been made by the U. S. Geological Survey and the U. S. Coast and Geodetic Survey. The profiles were flown at 20,000 feet above sea level and cover approximately 1,350,000 square miles of the Arctic Ocean between the North Pole...
Exposure of basement rock on the continental slope of the Bering Sea
D.W. Scholl, E. C. Buffington, D.M. Hopkins
1966, Science (153) 992-994
Profiles of repetitive seismic reflections reveal that the Bering continental slope, outer shelf, and rise overlay an acoustically reflective "basement" which extends at least 750 kilometers parallel to the trend of the slope. This acoustic basement is usually covered by several hundred meters of stratified sediments at the top and...
Evidence for an early recent warm interval in northwestern Alaska
David S. McCulloch, David M. Hopkins
1966, Geological Society of America Bulletin (77) 1089-1108
A warm interval that began at least 10,000 years ago and lasted until at least 8300 years ago is recorded in the coastal tundra covered area of northwestern Alaska by the presence of fossil wood of tree size or tree species, fossil beaver-gnawed wood found beyond the modern range of beaver, evidence of ice-wedge melting, buried soils, and soils that...
