Geologic map of the Bonpland PQC region of the Moon
S.R. Titley
1971, IMAP 678
This geologic map has been prepared from the photographic data returned by Ranger VII and is one of a series prepared from the data returned by the Ranger VII, VIII, and IX spacecraft. The map area, in Mare Cognitum, includes the Ranger VII impact point. The map shows the...
Preliminary results of induced polarization-resistivity surveys in the Northgate district, Colorado
Gordon Robert Francis Johnson
1971, Open-File Report 71-159
Induced polarization (I.P.) and resistivity surveys were made at selected locations in the Northgate district, Jackson County, Colorado. The objectives of the study were (1) to determine the feasibility of detecting and delineating pyrite-altered zones adjacent to fluorsparmineralized veins, and (2) to locate buried or obscured extensions of these fluorspar...
Ground water for irrigation in the Brooten-Belgrade area, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-E
Water for irrigation is needed to improve crop yields from sandy soils in the Brooten-Belgrade area. Ground-water supplies of sufficient quantity and suitable quality for irrigation are available in much of the area. Quaternary glacial drift, as much as 300 feet thick, is underlain by Precambrian crystalline rocks and possibly by...
Ground water for irrigation near Lake Emily, Pope County, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-J
In the Lake Emily area, thickness of the glacial drift ranges from about 200 feet to more than 400 feet. Within the drift are sand and gravel aquifers, some of which can yield adequate water supplies for irrigation. Outwash, as much as 60 feet thick, lies at the surface. The...
Summary of floods in the United States during 1966
J.O. Rostvedt
1971, Water Supply Paper 1870-D
This report describes the outstanding floods in the United States during 1966. The four most destructive floods occurred during March-April in the Red River of the North basin in northwestern Minnesota, during April-May in northeastern Texas, in August, in east-central Nebraska, and in December, in the Southwestern United States. For...
Subsurface waste disposal by means of wells - A selective annotated bibliography
Donald Robert Rima, Edith B. Chase, Beverly M. Myers
1971, Water Supply Paper 2020
Subsurface waste disposal by means of wells is the practice of using drilled wells to inject unwanted substances into underground rock formations. The use of wells for this purpose is not a new idea. As long ago as the end of the last century, it was common practice to drill...
Techniques and equipment required for precise stream gaging in tide-affected fresh-water reaches of the Sacramento River, California
Winchell Smith
1971, Water Supply Paper 1869-G
Current-meter measurements of high accuracy will be required for calibration of an acoustic flow-metering system proposed for installation in the Sacramento River at Chipps Island in California. This report presents an analysis of the problem of making continuous accurate current-meter measurements in this channel where the flow regime is changing...
Ground-water reconnaissance of selected sites in Rocky Mountain National Park and Shadow Mountain National Recreation area, Colorado
F.A. Welder
1971, Open-File Report 71-320
An evaluation of the ground-water supply potential at 30 sites within the Rocky Mountain National Park and Shadow Mountain National Recreation Area was made by the U.S. Geological Survey in 1967 and 1968. The work consisted of a geohydrologic reconnaissance, well inventory, and test drilling. The study sites are underlain...
