This report details discusses the Roosevelt Road Transmitter Site which was used from World War II to the Korean War as part of an Alaskan communications network. The bunker and support buildings were vandalized following its decommission-in in the mid-1960s, resulting in PCB contamination of the bunker and soils around the above-ground transmitter annex. CRREL conducted a ground-penetrating radar (GPR) investigation of the site in June 1996, at the request of the Directorate of Public Works on...

This document details the history of relative seas level changes and earthquake deformation cycles in Cook Inlet, Alaska. Multiple peat-silt couplets preserved in tidal marsh sediment sequences suggest that numerous great plate boundary earthquakes caused the coast around Cook Inlet, Alaska, to subside over the past 3500 years. Field and laboratory analyses of the two youngest couplets record the well-documented earthquake of AD 1964 and the penultimate one, approximately 850 call yr BP. Diatom...

The Alaska Division of Geological & Geophysical Surveys (DGGS) presents Short Notes on Alaska Geology 1995, the ninth issue in this series. There are ten papers, two each in Quaternary geology, structural geology, stratigraphy-sedimentology, and paleontology, and one each in economic geology and geochemistry. Almost all geographic regions of the State are represented. Overall, they reflect the wide range of subjects and broad geographic distribution of current geologic research in...

This report discusses the quaternary geology of the Upper Cook Inlet region which is dominated by deposits of glacier retreats that followed repeated advances from both adjacent and more distant mountains. At several levels high on the mountains, there are remnant glacial deposits and other features of middle or older Pleistocene age.

This document consists of a report on the Anchorage B-8 SE quadrangle and part of the Anchorage B-8 NE quadrangle that lies along the southeast side of Knik Arm, one of the two upper extensions of Cook Inlet. The map area is located in south-central Alaska mainly within the Municipality of Anchorage. The northwestern part of the map area, entirely within Knik Arm, is part of the Matanuska-Susitna Borough. Knik Arm, together with a broad embayment, Eagle Bay, occupies about one quarter of the map...

This resources is a report on the Anchorage B-8 SW Quadrangle, Alaska. The area of this map is located in south-central Alaska mainly within the Matanuska-Susitna Borough. The southeastern part is within the Municipality of Anchorage. Knik Arm, one of the two upper extensions of Cook Inlet. bisects the map area north to south. All land east of Knik Arm is included within Elmendorf Air Force Base and is substantially occupied by various facilities connected by a road network. Most of the area...

This report details the Anchorage A-8 NE quadrangle series of maps created on a 1:25,000 scale in the upper Cook Inlet-Knik Arm region for which geologic and surficial geologic maps have been published. The quadrangle lies entirely within the Municipality of Anchorage. Suburban Anchorage extends from the west into the map area in two prongs; the west-central prong is the more densely populated of the two and includes local commercial and educational centers, whereas the southwestern prong has...

The Anchorage B-7 SW quadrangle is located in south-central Alaska within the Municipality of Anchorage; the community of Eagle River is centered in the map area which is traversed north to south by Glenn Highway and the Alaska Railroad. The quadrangle is one of a series in the Anchorage-Knik Arm region for which surficial geologic maps have been completed recently at a scale of 1:25,000 (Daniels, 1981a,b; Reger, 1981a,b,c,d; Yehle and Schmoll, 1987a,b;1988; fig.2). The map area includes parts...
