Particularly in populated areas, detailed mapping is vital to site-specific planning. In contrast, regional maps such as this serve to place local, detailed mapping in context, to permit the extrapolation of data into unmapped areas, and to depict large-scale regional geologic features and patterns that are beyond the scope of local, detailed mapping. This map is also intended as a regional planning document that can assist in setting priorities for areas in need of more detailed mapping and assessment. It can be used to support regional decisionmaking on societal issues such as susceptibility of ground water in aquifers to contamination from surface-applied chemicals (see Soller and Berg, 1992). The map has also been used to help locate earthquake liquefaction features, by providing the regional framework needed to prioritize areas for search. This file contains data for surficial 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 and interpretation of available geologic data derived from about 850 sources of information. The map has three components that together provide the first regional three-dimensional view of these deposits. These components are the surface distribution of Quaternary sediments, the total thickness of Quaternary sediments, and the distribution of significant buried Quaternary units. (Subsurface information is not available for most of the mapped area, and therefore the depiction of buried units is uneven). Text and references to support the map are provided in paper format by Soller (1992) and on this CD-ROM (Soller and Packard, 1998). The digital version of the map is supported by a rudimentary base map adapted from existing paper and digital bases. To allow this large map to be digitized, it was first subdivided into 23 4-degree-by- 6-degree quadrangles, and each quadrangle was processed separately. Because the file size of the entire map area is quite large, the data are provided by quadrangle. This file contains data for a 4-degree-by-6-degree quadrangle. The geologic map was reviewed for its interpretations and general positional accuracy by Albert J. Froelich and James P. Owens (both USGS) and by representatives of the Geological Survey of Canada and the 23 State Geological Surveys in the map area.
