Map showing landslides in California that have caused fatalities or at least $1,000,000 in damages from 1906 to 1984
Understanding where landslide processes in California have been most severe is helpful in determining priorities for landslide mapping, mitigation measures, and preparedness planning. Although a few studies of landslide damage and fatalities have been published (see sources of data 12, 17, 34, 36, 40), and many more reports mention landslide damage and fatalities incidentally, our map is the first

Map showing slope movements in the Oak Forest Quadrangle, Greene County, southwestern Pennsylvania
This map is the first example in the eastern United States of a 1:24,000-scale 7.5– minute quadrangle map that identifies areas with slope—stability problems in detail. Such a map enables the user to make a rapid evaluation of the potential for mass movement. Furthermore, detailed slope movement inventory of this type can serve as a framework for statistical analyses of several factors that cause
Maps and interpretation of geochemical anomalies, Chuckwalla Mountains Wilderness Study Area, Riverside County, California
In March 1982, as part of the mineral resource investigations of the area, the U.S. Geological Survey conducted a reconnaissance geochemical survey of the Chuckwalla Mountains Wilderness Study Area (WSA), Riverside County, California. The survey involved collecting 196 heavy-mineral (panned) concentrates from stream sediment (the basis for these maps and the chief basis for the interpretations), t
Maps and tables showing data and analyses of semiquantitative emmission spectrometry and atomic-absorption spectrophotometry of rock samples, Ugashik, Bristol Bay, and part of Karluk quadrangles, Alaska
The accompanying maps and tables show analytical data and data analyses from rock samples collected in conjunction with geologic mapping in the Ugashik, Bristol Bay and western Karluck quadrangles from 1979 through 1981. This work was conducted under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP). A total of 337 samples were collected for analysis, primarily in areas of sur
Maps showing aeromagnetic data and interpretation of the Medford 1 degree by 2 degrees Quadrangle, Oregon-California
These maps are part of a folio of maps of the Medford 1o x 2o quadrangle, Oregon, prepared under the Conterminous United States Mineral Assessment Program. Other publications in this folio discuss the geology, geophysics, geochemistry, and mineral assessment of the Medford 1o x 2o quadrangle and are listed in the references at the end of this report.
