The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during the past 2+ million years, the period that includes all activities of the human species. 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 maps were compiled at 1:1,000,000 scale. This map is a product of collaboration of the Ontario Geological Survey, the University of Michigan, and the U.S. Geological Survey, and is designed for both scientific and practical purposes. It was prepared in two stages. First, separate maps and map explanations were prepared by the compilers. Second, the maps were combined, integrated, and supplemented by the editor. Map unit symbols were revised to a uniform system of classification and the map unit descriptions were prepared by the editor from information received from the compilers and from additional sources listed under Sources of Information. Diagrams accompanying the map were prepared by the editor. For scientific purposes, the map differentiates Quaternary surficial deposits on the basis of lithology or composition, texture or particle size, structure, genesis, stratigraphic relationships, engineering geologic properties, and relative age, as shown on the correlation diagram and indicated in the map unit descriptions. Deposits of some constructional landforms, such as kame moraine deposits, are distinguished as map units. Deposits of erosional landforms, such as outwash terraces, are not distinguished, although glaciofluvial, ice-contact, and lacustrine deposits that are mapped may be terraced. As a Quaternary geologic map it serves as a base from which a variety of maps relating Quaternary geologic history can be derived. For practical purposes, the map is a surficial materials map. Materials are distinguished on the basis of lithology or composition, texture or particle size, and other physical, chemical, and engineering characteristics. It is not a map of soils that are recognized and classified in pedology or agronomy. Rather, it is a generalized map of soils as recognized in engineering geology, or of substrata or parent materials in which pedologic or agronomic soils are formed. As a materials map it serves as a base from which a variety of maps for use in planning engineering, land use, or land management projects can be derived. Purpose: 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 Supplemental_Information: This database represents an attempt to digitally capture all the geologic information available on the published paper map. Separate coverages are provided for the map unit polygons, linear glacial features, point data for drumlins and direction of ice movement, and line coverages for the hydrology and topography. The description of map units and sources of information are both included as PDF files. The published maps of the Quaternary Geologic Atlas of the United States used three separate projections. To promote uniformity, the projection of this database was changed from Lambert Conformal Conic to Albers Equal Area and all subsequent digital databases will similarly be changed to Albers Equal Area Projection. Illustrations are provided showing areas of responsibility for the compilation of the map, relative ages of glacial phases in the Rainy and Superior lobe areas, the correlation of map units, radiocarbon age controls of a regional glacial readvance and an index map was created showing the location of quadrangles in the Quaternary geologic Atlas of the United States updated to show the quadrangles that have been published and the digital versions available. 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 ArcInfo format, this metadata file includes some ArcInfo-specific terminology. >The dataset for the Hudson River quadrangle consists of 10 coverages. > geo_net > gla_lin > gla_pnt > hydr_lin > topo_lin > bnd_lin > bnd_net > rd_lin > rr_lin > grid_lin > The dataset also includes an Arc/Info AML, keyfiles, lineset, shadeset, and markerset that will produce the gra, ai, or eps file of the geology and glacial features and the list of map units.

Browse_Graphic_File_Type: PDF Data_Set_Credit: The Quaternary Geologic Map of the Lake Nipigon 4° x 6° Quadrangle, United States, I-1420 (NM-16) was compiled by Edward V. Sado, Ontario Geological Survey; David S. Fullerton, U.S. Geological Survey; and William R. Farrand, University of Michigan, Department of Geological sciences. The state compilations were edited and integrated by David S. Fullerton, U.S. Geological Survey. The compilations of geology, hydrology, topography, and glacial features were converted to digital form by Techni Graphic Systems, Inc., of Fort Collins, CO, under contract with the U.S. Geological Survey and modified by Charles A. Bush, U.S. Geological Survey. Illustrations, wordprocessor files, and the National Atlas of Canada road, railroad, and boundary coverages were prepared by C. A. Bush, U.S. Geological Survey. Native_Data_Set_Environment: Windows_NT, 4.0, Intel ArcInfo version 9.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Compilation of geologic data: The accuracy of the map data is dependent on (1) the accuracy of the original source data, (2) the accuracy of transfer of that data to smaller scale bases by the compilers, (3) the procedures by which the compilers and the editor/integrator simplified or generalized the data, and (4) the procedures used by, and the objectivity exercised by, the editor/integrator in integration of adjacent parts of the map that were prepared by different compilers. Consequently, aspects of accuracy for the data set cannot be quantified. Digitization and attributing of compilation: Digitizing contractor scanned source stable-base material, vectorized scan, attributed files, and produced check plots and coverages. C.A. Bush proofread check plots and reviewed digital files; made final corrections as needed; produced graphical files and imported them into graphics program to prepare plot file; proofread cartographic product; prepared illustrations and word processing files of descriptions of map units and sources of information. The original paper map was scanned and recreated as PDF files. (The original map was thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature.) Logical_Consistency_Report: Polygon and chain-node topology are present. The ArcInfo commands BUILD and CLEAN were run to ensure the topological consistency of the data set. All polygons are labeled and were tested by using the ArcInfo command LABELERRORS. All polygons were checked for closure and intersections. Since this map was a collaboration of many compilers, some differences in the data that appear along the boundaries of compilation, represent differences in interpretation by the compilers, rather than actual differences in the materials. Completeness_Report: These coverages contain polygons for all the map units, lines for all the contacts and glacial features, and points for all the locations of eskers, direction of ice movement indicated by striated or grooved bedrock, and ice-molded landforms. All geologic data from the original map are expressed on this map. Any differences between elements on the original map and attributed polygons, arcs, and points in this database are inadvertent and should not be construed as deliberate alterations of the data. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The accuracy of location of polygons, lines, and points is consistent with the map scale of 1:1,000,000. The digital file was prepared at 1:1,000,000 nominal viewing scale. If the map is enlarged to larger scales (for example, 1:250,000, 1:100,000, or 1:24,000 scale), resolution of the map data is greatly diminished. Enlargement will not restore resolution that was lost by simplification or generalization of data. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: David S.

Process_Date: 2001 Process_Step: Process_Description: C. A. Bush acquired National Atlas of Canada 1:2,000,000 digital data for roads, railroads, and provincial and administrative boundaries in Canada. Data were clipped to cover only the area of the map. There are no user-defined attributes. A coverage was created containing map and international boundaries. These coverages do not exactly match the base used in preparation of the original Quaternary Atlas map, but are included for the user's convenience. Process_Date: 2006 Process_Step: Process_Description: Bush created illustration of the index map on the paper map in a drawing program and changed it to reflect the status of conversion of Quaternary Geologic Atlas quadrangles to digital databases. Bush scanned original printed map and also separated State compilation responsibility and map unit correlation diagrams, cleaned the scans, and converted them to PDF format. Map unit descriptions and sources of information as given on the printed map were scanned and converted by an Optical Character Recognition computer program into text files and to PDF format. Process_Date: 2006 Process_Step: Process_Description: Coverages of geology and glacial features were checked and corrected or changed. Additional items were included in the attributes. AML's were created to plot the data. Plots were imported into graphics program to create a plotfile of the digital map (Bush).
