Preliminary results of geological, geochemical, and geophysical studies in part of the Virginia City quadrangle, Nevada
Donald Harvey Whitebread, Donald B. Hoover
1968, Circular 596
Geological, geochemical, and geophysical studies in the Comstock Lode district and adjoining parts of the Virginia Range near Virginia City, Nev., have resulted in recognition of two geophysical anomalies and several geochemical anomalies in an area north of Virginia City. The geophysical anomalies were found during an induced-polarization survey carried...

Water resources of King County, Washington
Donald Richardson, J.W. Bingham, R. J. Madison, R. Williams
1968, Water Supply Paper 1852
Although the total supply of water in King County is large, water problems are inevitable because of the large and rapidly expanding population. The county contains a third of the 3 million people in Washington, most of the population being concentrated in the Seattle metropolitan area. King County includes parts...
Favorable areas for prospecting adjacent to the Roberts Mountains thrust in southern Lander County, Nevada
John Harris Stewart, Edwin H. McKee
1968, Circular 563
Recent geologic mapping by the U.S. Geological Survey of more than 2,500 square miles of a relatively little-studied part of central Nevada has outlined four areas favorable for the discovery of metallic mineral deposits. In these areas, lower Paleozoic carbonate rocks crop out below the Roberts Mountains thrust, a widespread...
