A gravity study of the northern part of the Arctic National Wildlife Range, Alaska
B. A. Kososki, H. N. Reiser, C. D. Cavit, R. L. Detterman
1978, Bulletin 1440
Interpretation of all publicly available onshore gravity data provides a basis for outlining regional elements of the basement and overlying structure in the northern part of the Arctic National Wildlife Range. Major post-Carboniferous sedimentary basins whose centers lie offshore on the Beaufort Shelf extend onshore in the northern part of...
Geology and Thermal History of Mammoth Hot Springs, Yellowstone National Park, Wyoming
Keith E. Bargar
1978, Bulletin 1444
Mammoth Hot Springs, located about 8 km inside the north entrance to Yellowstone National Park, consists of nearly 100 hot springs scattered over a score of steplike travertine terraces. The travertine deposits range in age from late Pleistocene to the present. Sporadic records of hot-spring activity suggest that most of...
Potential hazards from future eruptions of Mount St. Helens Volcano, Washington
Dwight Raymond Crandell, Donal Ray Mullineaux
1978, Bulletin 1383-C
Mount St. Helens has been more active and more explosive during the last 4,500 years than any other volcano in the conterminous United States. Eruptions of that period repeatedly formed domes, large volumes of pumice, hot pyroclastic flows, and, during the last 2,500 years, lava flows. Some of this activity...
Subsurface geology and porosity distribution, Madison Limestone and underlying formations, Powder River basin, northeastern Wyoming and southeastern Montana and adjacent areas
James A. Peterson
1978, Open-File Report 78-783
To evaluate the Madison Limestone and associated rocks as potential sources for water supplies in the Powder River Basin and adjacent areas, an understanding of the geologic framework of these units, their lithologic facies patterns, the distribution of porosity zones, and the relation between porosity development and stratigraphic facies is...
The Coffee Sand and Ripley aquifers in Mississippi
E. H. Boswell
1978, Water-Resources Investigations Report 78-114
The Coffee Sand and Ripley aquifers, of Cretaceous age, are in the Selma Group in northern Mississippi. The aquifers contain freshwater in an area of about 4,400 square miles in northern Mississippi. Water produced from the aquifers by public water systems and numerous industries in 1975 averaged about 4 Mgal/d....
