Water resources in the vicinity of municipalities on the western Mesabi Iron Range, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-B
Additional supplies of water are available near the municipalities on the western Mesabi Iron Range. Potential yields from both ground-water and surface-water sources are good. The most productive aquifers for ground-water supplies are the Biwabik Iron-Formation and the stratified glacial drift. Areas of stratified drift believed to have good water...
Water resources in the vicinity of municipalities on the west-central Mesabi Iron Range, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-C
Additional supplies of water are available near the municipalities or the west-central Mesabi Iron Range. The largest sources are the ground-water aquifers in the Biwabik Iron-Formation and the stratified glacial drift. Areas of stratified drift that probably have good water potential have been outlined. Surface-water supplies are negligible in the...
Water resources in the vicinity of municipalities on the eastern Mesabi Iron Range and the Vermilion Iron Range, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-F
Additional supplies of water are available near the municipalities on the eastern Mesabi Iron Range and the Vermilion Iron Range. On the eastern Mesabi Range the potential for additional development of both ground-water and surface-water supplies are good, and on the Vermilion Range the best potential for development is from...
Ground and surface water in the Mesabi and Vermilion Iron Range area, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-A
Within the Mesabi-Vermilion Iron Range area, water of good quality is available from the Biwabik Iron-Formation, from stratified drift, and from lakes and streams. About 700 bgy (billion gallons a year) leaves the area as surface water, of which about one-third comes from ground water. Leached, oxidized, and fractured parts of...
Identification and measurement of chlorinated organic pesticides in water by electron-capture gas chromatography
William L. Lamar, Donald F. Goerlitz, LeRoy M. Law
1965, Water Supply Paper 1817-B
Pesticides, in minute quantities, may affect the regimen of streams, and because they may concentrate in sediments, aquatic organisms, and edible aquatic foods, their detection and their measurement in the parts-per-trillion range are considered essential. In 1964 the U.S. Geological Survey at Menlo Park, Calif., began research on methods for...
Geology and hydrology of the Claiborne Group in western Tennessee
Gerald K. Moore
1965, Water Supply Paper 1809-F
The area of western Tennessee underlain by the Claiborne Group is about 7,200 square miles and lies on the east flank of the syncline that forms the Mississippi embayment. It includes the Mississippi Alluvial Plain and part of a dissected upland plateau. The Claiborne Group dips to the northwest at...
Geology of the Coeur d'Alene district, Shoshone County, Idaho
S. Warren Hobbs, Allan B. Griggs, Robert E. Wallace, Arthur B. Campbell
1965, Professional Paper 478
The Coeur d'Alene district, near the base of the northern panhandle of Idaho, is one of the world's larger lead- zinc and silver-producing areas. The greater part of the dis~rict i~ included within five map areas, from east to west the Pottsville, Mullan, Wallace, Kellogg, and Smelterville, which were geologically...
