Time-of-travel studies for the Little Androscoggin River, Maine
William J. Nichols, Barry M. Reed, Fred W. Greenlaw
1981, Open-File Report 81-640
Time-of-travel studies were conducted at flow durations of 20, 80, and 95 percent on the Little Androscoggin River from South Paris to Auburn, Maine. The river is about 29.3 miles long, and drains an area of about 354 square miles at its mouth.Traveltimes were determined by tracing the movement of...
Determination of pentachlorophenol in water and aquifer sediments by high-performance liquid chromatography
D.F. Goerlitz
1981, Open-File Report 82-124
Methods for the determination of pentachlorophenol (PCP) in water and aquifer sediments are presented. Reverse-phase high-performance liquid chromotography employing ion suppression and gradient elution is used. PCP can be determined directly in water at a lower limit of detection Of 0.2 micrograms per liter. For extracts of sediment, PCP can...
Guides to some volcanic terranes in Washington, Idaho, Oregon, and Northern California

1981, Circular 838
This guidebook arose out of a series of field trips held in conjunction with the Pacific Northwest American Geophysical Union meeting held in Bend, Oregon, September 1979. The PNAGU meeting included special volcanology sessions planned by William I. Rose, Jr., Bruce A. Nolf, amd David A. Johnston. Publication of the...
The Conterminous United States Mineral Appraisal Program; background information to accompany folio of geologic, geochemical, geophysical, and mineral resource maps of the Choteau 1 degree x 2 degrees Quadrangle, Montana
Robert L. Earhart, David J. Grimes, Reinhard W. Leinz, M. Dean Kleinkopf
1981, Circular 849
The Choteau l? x 2? quadrangle in northwest Montana was studied by an interdisciplinary research team in order to appraise its mineral resource and hydrocarbon potential The appraisal is based on field and laboratory investigations of the geology, geochemistry, and geophysics. The results of the investigations are published as a...
Effects of volcanism on the glaciers of Mount St. Helens
Melinda M. Brugman, Austin Post
1981, Circular 850-D
The cataclysmic eruption of Mount St. Helens May 18, 1980, removed 2.9 km2 (about 0.13 km3) of glacier snow and ice including a large part of Shoestring, Forsyth, Wishbone, Ape, Nelson, and all of Loowit and Leschi Glaciers. Minor eruptions and bulging of the volcano from March 27 to May...
Assessment of impacts of proposed coal-resource and related economic development on water resources, Yampa River basin, Colorado and Wyoming: A summary
Timothy Doak Steele, Donald E. Hillier
1981, Circular 839
Expanded mining and use of coal resources in the Rocky Mountain region of the western United States will have substantial impacts on water resources, environmental amenities, and social and economic conditions. The U.S. Geological Survey has completed a 3-year assessment of the Yampa River basin, Colorado and Wyoming, where increased...
Effects of Mount St. Helens eruption on selected lakes in Washington
N. P. Dion, S.S. Embrey
1981, Circular 850-G
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...
Annotated bibliography of remote sensing methods for monitoring desertification
A. S. Walker, Charles J. Robinove
1981, Circular 851
Remote sensing techniques are valuable for locating, assessing, and monitoring desertification. Remotely sensed data provide a permanent record of the condition of the land in a format that allows changes in land features and condition to be measured. The annotated bibliography of 118 items discusses remote sensing methods that may...
The Alaskan Mineral Resource Assessment Program; background information to accompany folio of geologic and resources maps of the Chignik and Sutwik Island quadrangles, Alaska
Robert L. Detterman, J. E. Case, D. P. Cox, D.E. Detra, T. P. Miller, Frederic H. Wilson
1981, Circular 802
The Chignik and Sutwik Island quadrangles (1:250,000) are a part of the Alaska Peninsula in southwestern Alaska. This circular and a companion folio of maps represent results of integrated field and laboratory studies by an interdisciplinary team on geology, geophysics, geochemistry, mineral resources, geochronology, and energy resources to provide a...
Biota and biological parameters as environmental indicators
P. E. Greeson, editor(s)

Hydrologic reconnaissance of the Wasatch Plateau-Book Cliffs coal-fields area, Utah
Kidd M. Waddell, P. Kay Contratto, C. T. Sumsion, John R. Butler
1981, Water Supply Paper 2068
Data obtained during a hydrologic reconnaissance in 1975-77 in the Wasatch Plateau-Book Cliffs coal-fields area of Utah were correlated with existing long-term data. Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches...
