Seismicity map of the state of Ohio
C. W. Stover, B.G. Reagor, S. T. Algermissen
1987, Miscellaneous Field Studies Map 1975
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Ohio, even though earthquakes...

Mineral resource potential map of the South Sierra Wilderness and the South Sierra Roadless Area, Inyo and Tulare Counties, California
Michael F. Diggles
1987, Miscellaneous Field Studies Map 1913-A
There are five areas with mineral resource potential and one area with geothermal energy potential in the South Sierra Wilderness and the South Sierra Roadless Area. The area south of Summit Meadows and the area south of Hogback Creek have moderate resource potential for tungsten and molybdenum in small skarn...
Map showing locations and statistical parameters of beach and offshore sand samples, Tutuila Island, American Samoa
J.R. Dingler, D.V. Carlson, A. H. Sallenger
1987, Miscellaneous Field Studies Map 1875
In April 1985, sand samples were collected from many of the beaches on Tutuila Island, American Samoa, and in July 1985, three bays were surveyed using side-scan sonar and shallow seismic profiling. During that second trip, scuba divers collected sand samples from the surveyed areas. Dingler and others (1986) describes...
