During the Pliocene to middle Pleistocene, pluvial lakes in the western Great Basin repeatedly rose to levels much higher than those of the well-documented late Pleistocene pluvial lakes, and some presently isolated basins were connected. Sedimentologic, geomorphic, and chronologic evidence at sites shown on the map indicates that Lakes Lahontan and Columbus-Rennie were as much as 70 m higher in the early-middle Pleistocene than during their late Pleistocene high stands. Lake Lahontan at its 1400-m shoreline level would submerge present-day Reno, Carson City, and Battle Mountain, and would flood other now-dry basins. To the east, Lakes Jonathan (new name), Diamond, Newark, and Hubbs also reached high stands during...

This report provides background information on the regionalgeochemical data provided by the US Geological Survey to the USForest Service and Bureau of Land Management Interior ColumbiaBasin Ecosystem Management Project (ICBEMP). This report is one ina series of digital maps, data files, and reports generated by theUS Geological Survey to provide geologic process and mineralresource information to the Interior Columbia Basin EcosytemManagement Project. The various digital maps and data files arebeing used in a GIS-based ecosystem assessment including ananalysis of diverse questions relating to past, present, and futureconditions within the general area of the Columbia River Basin eastof the Cascade Mountains.

The coverages were created using the gridded data available fromthis ftp site. Most of the gridded data for the United States is ata spacing of 0.1 degrees latitude and longitude. The higherresolution data available for California, Nevada, and part ofArizona and Utah were used for both the U.S. and Western U.S. maps.The gridded data for this area is at a spacing of 0.05 degreeslatitude and longitude.

This CD presents maps derived from a subset of the National Uranium Resource Evaluation(NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data.Approxiamately 260,000 samples were analyzed in the continental U.S. and consisted ofsolid samples, including stream, lake, pond, spring, and playa sediments, and soils.Data for eleven elements were analyzed and included on this release of the NationalGeochemical Atlas CD: Na, Ti, Fe, Cu, Zn, As, Ce, Hf, Pb, Th, and U.The National Uranium Resource Evaluation (NURE) program of the Department of Energy (DOE) collecteda vast amount of chemical data on sediment, soil, and water samples from the United States in thelate 1970's and early 1980's. This element of the...

This CD-ROM contains a digital version of the Geologic Map of theUnited States, originally published at a scale of 1:2,500,000 (Kingand Beikman, 1974b). It excludes Alaska and Hawaii. In addition tothe graphical formats, the map key is included in ASCII text.A geographic information system (GIS) allows combining andoverlaying of layers for analysis of spatial relations not readilyapparent in the standard paper publication. This disc contains onlygeology. However, digital data on geology, geophysics, andgeochemistry can be combined to create useful derivative products--for example, see Phillips and others (1993).This CD-ROM contains a copy of the text and figures fromProfessional Paper 901 by King and Beikman (1974a)....

Debris flows, debris avalanches, mud flows and lahars arefast-moving landslides that occur in a wide variety of environmentsthroughout the world. They are particularly dangerous to life andproperty because they move quickly, destroy objects in their paths,and can strike with little warning. The purpose of this map is toshow where debris flows have occurred in the conterminous UnitedStates and where these slope movements might be expected in thefuture.
