Abstract:

This file contains data for miscellaneous glacial boundaries, 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.

Purpose:

This map is a regional overview and is intended to supplement the more detailed work on which it is based. 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.

Supplemental_Information:

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. Other data layers on USGS DDS-38 (qsurf, qsubsurf, qveneer, qmiscln, qmiscpt, streams, roads, cities, polbnds). References_Cited:

Attribute_Accuracy_Report:

Reliability of map data varies by State and is addressed in greater detail in USGS Bulletin 1921, "Text and References To Accompany 'Map Showing the Thickness and Character of Quaternary Sediments in the Glaciated United States East of the Rocky Mountains'"(Included on this CD-ROM). Geologic data were compiled prior to 1987. Therefore, newer mapping may alter some information shown on this map. The map is intended for use at the scale of its compilation (1:1,000,000).

Process_Step:

Process_Description:

This file is derived from a conventionally compiled map prepared in the following manner. Source map information, in paper format, was photographically resized to compilation scale for interpretation and manual compilation. The map base was composed of hand-mosaicked 4-degree-by-6-degree 1:1,000,000-scale quadrangles from the International Map of the World Series (Lambert Conformal Conic projection) or the Army Map Service (Modified Polyconic projection of the International Map of the World). To facilitate map printing, map data were divided into quadrangles for digitization, preparation f files in geographic information system format, and computer generation of printing negatives, according to techniques described in Soller and others (1990). To facilitate other uses for the digital map files, they were reprocessed for public release on this CD-ROM, USGS Digital Data Series DDS-38.
