An inventory of suspended sediment stations and type of data analysis for Pennsylvania streams, 1947-1970
Arthur N. Ott, Allen B. Commings
1972, Report
Data concerning suspended sediment concentrations and loads, frequency of occurrence of suspended sediment concentrations, and long-term trends of annual suspended sediment loads are important tools for today's environmental manager. These data are required background for those concerned with establishing and enforcing erosion and sedimentation control regulations and sediment concentration or...
Water quality at Miami International Airport, Miami, Florida, 1971–72
Herbert J. Freiberger, Benjamin F. McPherson
1972, Open-File Report FL 72-023
The quality of water, sediment, and biota was determined at four sites in canals and drainage ditches at Miami International Airport (MIA) during high- and low-water periods and during summer and winter 1971–72. Concentrations of common ions, such as calcium, sodium, chloride, and magnesium, tended to be above average for...
Appraisal of shallow ground-water resources, Pueblo Army Depot, Colorado
Frank A. Welder, R. Theodore Hurr
1972, Open-File Report 72-447
The water supply for the Pueblo Army Depot, 15 miles wast of Pueblo, Colo., is obtained from wells that tap an aquifer in terrace alluvium. Withdrawals have resulted in a water-level decline of 27 feet, which adversely affects the discharge rate of individual wells. Furthermore, excessive pumpage has resulted in...
The status of mineral resource information on the major land withdrawals of the Alaska Native Claims Settlement Act of 1971
Alaskan Geology Branch
1972, Open-File Report 72-394
This report is an analysis of the adequacy of the present level of geologic knowledge for making mineral resource potential evaluations of 126 federal land withdrawals made under the Alaska Native Claims Settlement Act. The withdrawals considered are Native village and regional deficiency areas (Sec. 11.A.3, ANCSA), classification and national...
Placer deposits of Alaska
Edward Huntington Cobb
1972, Open-File Report 72-71
Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their...
Oil-shale assays on Grand Mesa, west-central Colorado
John R. Donnell
1972, Open-File Report 72-93
The attached diagram shows the Fischer assay histograms of oil shale from 4 core holes drilled on Grand Mesa. Core-hole locations are shown on-an insert map of Grand Mesa in the lower right corner of the diagram....
Geological and geophysical investigations of an Apollo 9 photo anomaly near Point of Pines, Arizona
Calvin S. Bromfield, G. P. Eaton, D. L. Peterson, J.C. Ratte
1972, Open-File Report 72-51
An infrared photograph of southeastern Arizona, taken during the Apollo 9 multispectral terrain photography experiment in 1969, reveals a ringlike feature, some 3-4 miles (5-6 kin) in diameter, on the Natanes Plateau, 35 miles (56 kin) north of the town of Safford. Because the feature occurs in an area of...
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...
