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. 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. NOTE: This map is the product of collaboration of the Texas Bureau of Economic Geology and the U.S. Geological Survey, and is intended for both scientific and practical purposes. It was prepared in two stages. First, a map and map explanation was prepared by the State compiler. Second, information on the map was integrated with that of the adjacent map, supplemented, and related to a uniform map symbol classification by the editors. Map unit descriptions also were combined, supplemented, and coordinated with those of other maps of this series so that individual unit descriptions are applicable throughout both this map and all other maps of the series. Less than forty percent of the surficial deposits of the United States have been mapped and described. Traditionally, mapping of surficial deposits has focused on glacial, alluvial, eolian, lacustrine, marine, and landslide deposits. Slope and upland deposits have been mapped in detail only in restricted areas. However, engineering construction and important problems of land use and land management are associated with regions that have extensive upland residual deposits. These materials differ widely in physical characteristics. Therefore, an effort has been made to classify, map, and describe them, based in large part on unpublished interpretations of individuals, published and unpublished subsoil data, and the distribution of bedrock parent materials. The classification is crude, but is a first step toward a more refined and useful product. For scientific purposes, the map differentiates Quaternary surficial deposits based on a combination of criteria, such as lithology, texture, genesis, stratigraphic relationships, and age, as shown on the correlation diagram and indicated in the map unit descriptions. Some geomorphic features, such as beach ridges, are distinguished as map units. Erosional features, such as stream terraces, are not distinguished, and differentiation of sequences of alluvial deposits of different ages is rarely possible at a scale of 1:1,000,000. For practical purposes, the map is a surficial materials map, on which materials are distinguished on the basis of texture, composition, and local specific characteristics such as swelling clay. It is not a map of pedologic or agronomic soils. Rather it is a generalized map of soils as recognized in engineering geology, or of subsoils or parent materials from which pedologic and agronomic soils are formed. As a materials map it serves as a base from which engineering, land-use­planning, or land-management maps can be derived. 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 features, point feature, and line coverages for the hydrology and topography. The description of map units and sources of information are both included as a PDF file. 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 an index to the International Map of the World 1:1,000,000; areas of responsibility for the compilation of the map; distribution and thickness of loess in the map area; and showing the correlation of map units. 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 Monterrey quadrangle consists of 8 coverages. > geo_net > geo_lin > hydr_lin > bnd_lin > bnd_poly > rd_lin > rr_lin > grid_lin > The dataset also includes an ArcInfo AML, markerset, lineset, and shadeset that will produce the Illustrator or ArcInfo PDF file of the geology and list of map units.

Browse_Graphic_File_Type: PDF Data_Set_Credit: The Quaternary Geologic Map of the Monterrey 4° x 6° Quadrangle, United States, I-1420 (NG-14) was compiled by: David W. Moore, U.S. Geological Survey, and E.G. Wermund, Jr., Texas Bureau of Economic Geology. The map was edited and integrated by David W. Moore and Gerald M. Richmond, U.S. Geological Survey. The compilation of geology and hydrology were converted to digital form by TechniGraphic Systems, Inc., of Fort Collins, CO, under contract with the U.S. Geological Survey and modified by Charles A. Bush. The illustrations, word-processor files, and National Atlas coverages were prepared by Bush. Native_Data_Set_Environment: Windows_XP, 4.0, Intel ArcInfo version 9.2 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 larger 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 contact lines and water boundaries, vectorized scan, attributed files, and produced check plots and coverages of map units. Bush digitized hydrography and topography from the stable-base mylar. C.A. Bush rectified differences between the geology and the hydrology, proofread check plots, added additional attribution, 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. Completeness_Report: These coverages contain polygons for all the map units, and lines for all the contacts and shorelines. All geologic data from the original map are expressed on this map. Any differences between elements on the original map and attributed polygons or arcs 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.

Process_Date: 1998 Process_Step: Process_Description: C.A. Bush added water identification to the hydrology coverage. Coverage of geology was 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. Process_Date: 2010 Process_Step: Process_Description: Bush acquired National Atlas of the United States 1:2,000,000 digital data for roads, railroads, and county boundaries in the United States. Data was clipped to cover only the area of the map. Since the files are intended only for the user's reference, and to reduce file size, all attributes were removed from the railroad coverage. All attributes were removed from the roads coverage except U.S. and State highway designations. A coverage was created containing map boundaries, and State and county 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: 2010 Process_Step: Process_Description: C.A. 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. Process_Date: 2010 Process_Step: Process_Description: 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(Bush).
