An appraisal of groundwater for irrigation in the Appleton area, west-central Minnesota
Steven J. Larson
1975, Open-File Report 75-32
Supplemental irrigation of well-drained sandy soils has prompted an evaluation of ground water in the Appleton area. Glacial drift aquifers are the largest source of ground water. The surficial outwash sand and gravel is the most readily available and a really extensive drift aquifer and underlies much of the sandy...
Assessment of geothermal resources of the United States, 1975
David L. Williams
Donald Edward White, editor(s)
1975, Circular 726
This assessment of geothermal resources of the United States consists of two major parts: (1) estimates of total heat in the ground to a depth of 10 km and (2) estimates of the part of this total heat that is recoverable with present technology, regardless of price. No attempt has...
The Alaskan mineral resource assessment program; background information to accompany folio of geologic and mineral resource maps of the Nabesna Quadrangle, Alaska
Donald H. Richter, N. R. D. Albert, D.F. Barnes, Andrew Griscom, S.P. Marsh, D.A. Singer
1975, Circular 718
The Nabesna quadrangle in south-central Alaska is the first of the l:250,000-scale Alaskan quadrangles to be investigated by an interdisciplinary research team in order to furnish a mineral resource assessment of the State. The assessment of the 17,600-km 2 16,800-mi21 quadrangle is based on field and laboratory investigations of the...
Map showing availability of hydrologic data published by the U.S. Environmental Data Service and by the U.S. Geological Survey and cooperating agencies, greater Denver area, Front Range Urban Corridor, Colorado
E. R. Hampton
1975, IMAP 856-C
What is the rainfall of this region? What areas are prone to periodic flooding? What is the water supply? What is the chemical quality of the ground water and water in the streams? How deep is the water table? Which streams are gaged, and where? These and similar questions are...
Titanium minerals in deposits of other minerals
Eric R. Force
1975, Open-File Report 75-34
Titanium minerals in amounts equivalent to a significant portion of present world production are moved but not recovered from mines of other commodities. Resources of this type total in the millions of tons of contained TiO2. Among the possible sources for byproduct titanium are (1) ilnenite and minor rutile detrital...
Bedrock topography of northeast Iowa
Robert E. Hansen
1975, IMAP 933
The bedrock in Iowa (Hershey, 1969) is generally overlain by deposits of glacial drift and alluvium, which range in thickness from less than 1 foot (0.3 m) to more than 400 ft (18 m), respectively. The configuration of the bedrock surface is the result of a complex system of ancient...
Chemical and biological quality of water in part of the Everglades, southeastern Florida
Bradley G. Waller, James E. Earle
1975, Water-Resources Investigations Report 75-56
A comprehensive monitoring network was established in a part of the Everglades to evaluate the quality of water being delivered to Everglades National Park. Physical, chemical, and biological parameters were determined in surface water, bottom sediment, and bulk precipitation (rainfall and dry fallout).The geology of the area, bottom sediment, bulk...
