The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...

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 geographic information system (GIS) data layer shows thedominant lithology and geochemical, termed lithogeochemical,character of near-surface bedrock in the New England regioncovering the states of Connecticut, Maine, Massachusetts, NewHampshire, Rhode Island, and Vermont. The bedrock units in themap are generalized into groups based on their lithologicalcomposition and, for granites, geochemistry. Geologic provincesare defined as time-stratigraphic groups that share common featuresof age of formation, geologic setting, tectonic history, and lithology.This data set incorporates data from digital maps of two NAWQAstudy areas, the New England Coastal Basin (NECB) and theConnecticut, Housatonic, and Thames River...

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 file contains data for selected significant, buried Quaternary sediments, which is one layer of information on this CD-ROM, USGS Digital Data Series #38 (Soller and Packard, 1998). Together, all layers (10 of them) compose the digital version of a 1:1,000,000- scale map of Quaternary deposits (including both glacial and Holocene sediments) compiled for the glaciated area of the United States east of the Rocky Mountains (that is, the area covered by the Laurentide ice sheets). Parts of southern Ontario, areas beneath the Great Lakes, and parts of the submerged eastern seaboard are also included on the map. The paper version of the map is Soller (1993a, b, 1994, 1998, and in press). The map is a regional synthesis...

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.

The data are those used to make a large-format, colored map ofearthquakes in the northeastern United States and adjacent partsof Canada and the Atlantic Ocean (Wheeler, 2000; Wheeler andothers, 2001; references in Data_Quality_Information, Lineage).The map shows the locations of 1,069 known earthquakes ofmagnitude 3.0 or larger, and is designed for a non-technicalaudience. Colored circles represent earthquake locations, coloredand sized by magnitude. Short descriptions, colonial-erawoodcuts, newspaper headlines, and photographs summarize thedates, times of day, damage, and other effects of notableearthquakes. The base map shows color-coded elevation, shaded toemphasize relief.
