A digital representation of a glacial aquifer map for the northeastern United States (Kontis and others, 2004; http://pubs.er.usgs.gov/publication/pp1415C; Plate 3) has been prepared by staff of the U.S. Geological Survey. Aquifer data was digitally compiled from a georeferenced version of Plate 3, along with supplemental aquifer maps that covered portions of the northeast.

The National Geologic Map Database (NGMDB) is a Congressionally mandated national archive of geoscience maps, reports, and stratigraphic information. The Geologic Mapping Act of 1992 and its Reauthorizations calls for the U.S. Geological Survey and the Association of American State Geologists (AASG) to cooperatively build this national archive, according to technical and scientific standards whose development is coordinated by the NGMDB. The NGMDB consists of a comprehensive set of publication citations, stratigraphic nomenclature, downloadable content in raster and vector formats, unpublished source information, and guidance on standards development. The NGMDB contains information on more than 110,000 maps and...

The Glacial Environments and Surficial Sediments geodatabase (GESS) data includes a polygon file with multiple attributes which describe the lithology, geomorphology, and related depositional environment of Quaternary-age surfical sediments in the glaciated conterminous United States. These attributes include: the map unit (GESS_MU), a geomorphic modifier (GESS_Modifier), a sediment stratification indicator (SedStrat), and a a sediment texture classification (Texture6). Possible GESS_MU values include: alluvial sediment, colluvial sediment, eolian sediment, lacustrine sediment, marine sediment, organic sediment, outwash, ice-contact deposits, island, residual soils, soliflucted sediment, till, bedrock, fill, and...

The bedrock geology for the Glacial Environments and Surficial Sediments (GESS) geodatabase is an amalgamation of several “Integrated Geologic Map Databases for the United States” (Dicken and others, 2008; Ludington and others, 2007; Nicholson and others, 2007-1,-2,-3; Stoeser and others, 2007). Using the LITH62 and LITH62MINO attribute values from that series of maps and the associated lithclass 6.2 code text descriptions from the geodatabase, spatial elements of that geodatabase were grouped. A new GESS attribute was created, “Litho_class,” and each spatial element was given a Litho_class value of non-carbonate sedimentary rock, carbonate rock, non-carbonate metamorphic rock, volcanic rock, plutonic rock, or unconsolidataed...

The Hydrogeologic Terranes dataset includes separate polygon and line feature classes. The polygon feature class divides the glaciated United States into seventeen distinct terranes using a geologically based approach. Each terrane contains Quaternary sediment that is derived from a common depositional history and can be characterized by texture and thickness. Delineation of hydrogeologic terranes was based on an interpretation of existing geologic mapping of surficial and Quaternary deposits, and thickness of unconsolidated material. Overall thickness of Quaternary sediment was used to qualitatively rank the generalized complexity of geologic framework in each terrane: "lower" complexity (assigned a terrane code...
