Clay deposits of the Connecticut River Valley, Connecticut: a special problem in land management
William H. Langer
1972, Open-File Report 72-218
When man first settled the United States, two natural features favored settlement; flat land that was easy to build on and to farm, and a nearby river that could act as a source of water, transportation, and power. The Connecticut River Valley from Middletown, Ct. north past the Connecticut-Massachusetts state...
Surficial geology of the Mount Tom quadrangle, Massachusetts

Reconnaissance engineering geology of the Haines area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-229
The Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in urban areas. Study of the Haines area constitutes an integral part of an overall program to evaluate earthquake and other geologic hazards in most of the larger Alaska coastal communities. The evaluations...
Regional and other general factors bearing on evaluation of earthquake and other geologic hazards to coastal communities of southeastern Alaska
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-230
The great Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in seismically active regions. As a result, nine communities in southeastern Alaska were selected for reconnaissance investigations as an integral part of an overall program to evaluate earthquake and other geologic hazards...

1972, Open-File Report 72-268
A reconnaissance of surface and subsurface sediments to a maximum depth of 244 feet below the sea floor shows that natural mercury anomalies from 0.2 to 1.3 ppm have been present in northeastern Bering Sea since early Pliocene. The anomalies and mean values are highest in modern beach (maximum 1.3...
