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.

Data sources used in this process:
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).
Only sparse information on the nature of buried geologic units is available, so the file "qsubsrf" is far from comprehensive.
Note that the "qsurf" and "qveneer" files both show texture and origin of surficial geologic units; the distinction between the files is based on estimated thickness of the unit, quality and completeness of source information, and the cartographic design requirements of the paper map.
