These materials 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 one way or another to these surface materials that are referred to collectively by many geologists as regolith, the mantle of fragmental and generally unconsolidated material that overlies the bedrock foundation of the continent. The map is based on 31 published maps in the U.S. Geological Survey's Quaternary Geologic Atlas of the United States map series (U.S. Geological Survey Miscellaneous Investigations Series I-1420). It was compiled at 1:1,000,000 scale, to be viewed as a digital map at 1:2,000,000 nominal scale and to be printed as a conventional paper map at 1:2,500,000 scale. This map is not a map of soils as recognized and classified in agriculture. Rather, it is a generalized map of soils as recognized in engineering geology, or of substrata or parent materials in which agricultural, agronomic, or pedologic soils are formed. Where surficial deposits or materials are thick, agricultural soils are developed only in the upper part of the engineering soils. Where they are very thin, agricultural soils are developed through the entire thickness of a surficial deposit or material. The surficial geologic map provides a broad overview of the areal distribution of surficial deposits and materials. It identifies and depicts more than 150 types of deposits and materials. In general, the map units are divided into two major categories, surface deposits and residual materials. Surface deposits are materials that accumulated or were emplaced after component particles were transported by ice, water, wind, or gravity. The glacial sediments that cover the surface in much of the northern United States east of the Rocky Mountains are in this category, as are the gravel, sand, silt, and clay that were deposited in past and present streams, lakes, and oceans. In contrast, residual materials formed in place, without significant transport of component particles by ice, water, wind, or gravity. They are products of modification or alteration of pre-existing surficial deposits, surficial materials, or bedrock. For example, intense weathering of solid rock, or even stream deposits, by chemical processes may produce a residual surficial material that is greatly transformed from its original physical and chemical state. In recent years, surficial deposits and materials have become the focus of much interest by scientists, environmentalists, governmental agencies, and the general public. They are the foundations of ecosystems, the materials that support plant growth and animal habitat, and the materials through which travels much of the water required for our agriculture, our industry, and our general well being. They also are materials that easily can become contaminated by pesticides, fertilizers, and toxic wastes. In this context, the value of the surficial geologic map is evident The map and its digital database provide information about four major aspects of the surficial materials, through description of more than 150 types of materials and depiction of their areal distribution. The map unit descriptions provide information about (1) genesis (processes of origin) or environments of deposition (for example, deposits related to glaciation (glacial deposits), flowing water (alluvial deposits), lakes (lacustrine deposits), wind (eolian deposits), or gravity (mass-movement deposits)), (2) age (for example, how long ago the deposits accumulated or were emplaced or how long specific processes have been acting on the materials), (3) properties (the chemical, physical, and mechanical or engineering characteristics of the materials), and (4) thickness or depth to underlying deposits or materials or to bedrock. This approach provides information appropriate for a broad user base. The map is useful to national, state, and other governmental agencies, to engineering and construction companies, to environmental organizations and consultants, to academic scientists and institutions, and to the layman who merely wishes to learn more about the materials that conceal the bedrock. The map can facilitate regional and national overviews of (1) geologic hazards, including areas of swelling clay and areas of landslide deposits and landslide-prone materials, (2) natural resources, including aggregate for concrete and road building, peat, clay, and shallow sources for groundwater, and (3) areas of special environmental concern, including areas of intense erosion and areas of potential contamination of soil and groundwater. The map also includes lines depicting the maximum limits of glacial advance during selected time periods. Purpose: This geospatial database has been prepared with a degree of detail appropriate for viewing at a scale of 1:2,000,000. Because of the degree of generalization required, the map is intended for regional and national analysis, rather than for detailed analysis in specific areas. It depicts the surficial deposits and materials at or near the land surface, where most human interaction occurs. It does not depict the bedrock geology, which is shown elsewhere in the National Atlas. Supplemental_Information: The data set for the Surficial Deposits and Materials of the Eastern and Central United States (East of 102 Degrees West Longitude) consists of two layers: surficial deposits and materials, and glacial limits. The data are available as shapefiles or Arc/Info Export files. The data layers are distributed and should be used together. All the data layers were created as Arc/Info coverages and converted to other formats for distribution purposes. The following files are included: ussurfm020 - Map units, as polygons, geographic projection glacal020 - Glacial limits, as lines without line decorations, geographic projection ussurflam - Map units, as polygons, Lambert_Azimuthal projection glaciallam - Glacial limits, as lines without line decorations, Lambert_Azimuthal projection Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Arc/Info format, this metadata file may include some Arc/Info-specific terminology.

Each 1:1M scale, 4° x 6°, map of the Quaternary Geologic Atlas map series was simplified (e.g., some small or narrow units were deleted; two or more map units were combined as a single unit for the National Atlas map). In some quadrangles, map units were revised or modified to accommodate information that was not available when the maps were published (e.g., the age of a deposit subsequently may have been revised). The contacts of the new (simplified or revised) map units were inked on a paper copy of each 4° x 6° quadrangle and letter symbols were assigned to the new map units.

The individual map unit descriptions for each published map were cut with a scissors and labeled with respect to genetic class, age or age range, and quadrangle name. The cut descriptions were sorted first by genetic classes (e.g., eolian deposits, alluvium, solution residuum). Then they were sorted within the genetic classes by ages or age classes (e.g., Holocene; late Pleistocene and middle Pleistocene). Within each genetic heading and age or age class subheading, the cut descriptions then were grouped on the basis of particle size or texture, lithology or composition, engineering properties, stratigraphic relationships, and other information in the unit descriptions. The individual stacks of unit descriptions then were taped onto pages in notebooks and assigned unit names and letter symbols. The letter symbols chosen were arbitrary. The list of map units for the surficial geologic map then was prepared from the hierarchy of units organized in the notebooks. Some map units are greatly simplified. As an example, map unit cl on the surficial geologic map is represented by 13 different map units in 11 4° x 6° quadrangles. All 13 units were colluvium derived from clastic rocks (conglomerate, sandstone, quartzitic sandstone, siltstone, shale) in various combinations. The distinctions on the published maps at 1:1M scale are not warranted on this map at a nominal scale of 1:2M. The unit descriptions for the surficial geologic map were compiled from all of the cut-and-taped descriptions that were relegated to a new map unit. The published descriptions were generalized and simplified. Process_Date: 2000 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: David S.

The map units then were traced in black ink on the mylar overlay. The contacts of surficial deposits and materials in and adjacent to major valleys were traced onto the overlay by matching stream junctions, river bends, lakes, reservoirs, and other components of the hydrology on the paper map and the overlay. That procedure was accomplished in increments. The geologic contacts were "fitted" on the mylar in a major valley within an area approximately one inch square. Then they were "fitted" in an adjacent square. When the geology in and adjacent to all of the major valleys had been transferred to the mylar base, the geology in the areas between valleys was "fitted" in increments using the valley deposits and materials, hydrographic features (e.g., minor streams and lakes), state boundaries, and other guides. No attempt was made to "fit" the surficial geology directly to the planimetric base for the National Atlas of the United States.

Deposits and residual materials are distinguished in part on the basis of particle size or texture, particle lithology or composition, and other physical, chemical, and engineering characteristics. It is not a map of soils that are recognized in agriculture, agronomy, or pedology. Rather, it is a generalized map of soils as recognized in engineering geology, or of substrata or parent materials in which agricultural soils are formed. Several classification systems for engineering and agricultural soils are in use, and terminology differs. The textural or particle size divisions (e.g., clay, sand, pebbles, boulders) and the matrix nomenclature (e.g., loamy sand, clay loam, silty clay) of the U.S. Department of Agriculture are used here to ensure uniformity of terminology.
