Geochemical, aeromagnetic, and generalized geologic maps showing distribution and abundance of gold and copper, Golconda and Iron Point quadrangles, Humboldt County, Nevada
R. L. Erickson, S.P. Marsh
1971, Miscellaneous Field Studies Map 314
Detailed geologic and geochemical studies of the four 7 1/2-minute quadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun during the 1969 summer field season.  The objectives of the project are to map the geology of this structurally complex area at 1:24,000 scale and...

Municipal and industrial wastewater loading in the San Francisco Bay, California, 1970
W. G. Hines, R.H. Palmer
1971, Miscellaneous Field Studies Map 332
The purpose of this release is to describe the approximate volumes and significant pollutional loading attributable to municipal and industrial wastewater discharged into the San Francisco Bay. The six receiving-water regions (fig.1) are the same as those used previously by Pearson, Storrs, and Selleck (1969) in describing results of the comprehensive...
Reconnaissance of the Sturgeon River, a cold-water river in the northcentral part of Michigan's southern peninsula
G. E. Hendrickson, C. J. Doonan
1971, Hydrologic Atlas 353
The cold-water streams of the northern states provide unique recreational values to the American people (wilderness or semi-wilderness atmosphere, fast-water canoeing, trout fishing), but the expanding recreational needs must be balanced against the growing demand of water for public and industrial supplies, for irrigation, and for the dilution of sewage...
