Description:
Abstract:
U.S. Geological Survey (USGS) Miscellaneous Investigations Series Map I-1970 is a 1:1,000,000-scale map of Quaternary deposits (including both glacial and glacially related sediments, and any overlying Holocene sediments) compiled for the glaciated area of the United States east of the Rocky Mountains (that is, the area covered by the Laurentide ice sheets). Parts of southern Ontario, areas beneath the Great Lakes, and parts of the submerged eastern seaboard also are included on the map. The map has four principal geologic components that together provide the first regional three-dimensional view of these deposits. These components are: (1) the surface distribution of Quaternary sediments; (2) the total thickness of Quaternary sediments; (3) significant thin, surficial Quaternary units (“veneers” of sediment overlying the unit generally mapped for a given area); and (4) significant buried Quaternary sediments.

The map is a regional synthesis and interpretation of available geologic data derived from about 850 sources of information. It was published in four sheets, as Map I-1970-A--D (Soller, 1993a, 1994, 1997, and 1998). It also was simplified and printed at the reduced scale of 1:3,500,000 (Soller, 1993b, 2001). Text and references to support the map are provided by Soller (1992). The Geographic Information System (GIS) data from which the map was printed were released on CDROM (Soller and Packard, 1998).

To allow this large map to be printed, new digital methods were developed (Soller and others, 1990). The GIS and digital printing technology of the early 1990s required that the map be divided into manageable pieces. Therefore, the mosaic of 23 4-degree by 6-degree International Map of the World Series quadrangles, upon which the map was compiled, was taken apart, and each quadrangle was processed separately. Because the file size was quite large for a database of the entire map area, GIS files in the first version of this database (Soller and Packard, 1998) were provided by quadrangle rather than for the entire area. For each of these quadrangles, the geologic information was supported by a rudimentary vector base map adapted from existing paper and digital bases. With gradual advances in GIS technology, and owing to continued user requests for the map database, it became incumbent on us to reprocess the database in order to ensure its usefulness in a modern GIS. Data Series 656 contains the updated database, organized in ten feature classes in an ESRI Geodatabase.

Reprocessing a published database for these and other reasons will, in time, become necessary for other agency publications. The experience gained in updating this map for use in a modern GIS may inform agencies as they develop plans to prioritize older publications in need of updating and may help agencies in estimating the resources necessary to address this important responsibility.
Purpose:
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 decision-making 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 been used as a regional framework in numerous scientific studies, and to support research and discussion on numerous societal issues. For example, it was used to help locate earthquake liquefaction features, by providing the regional framework needed to prioritize areas for search.
Supplemental_Information:
An extended description of the geologic map units, a summary of factors affecting sediment texture and distribution, and a listing of map sources are provided in USGS Bulletin 1921 (Soller, 1992). Methods developed for digitizing, processing, and printing the map are detailed in a user's manual (Soller and others, 1990). The base map data provided with this publication were derived from (1) hard-copy separates (streams layer) of the International Map of the World Series, which were scanned and vectorized and (2) vector data (State boundaries, major roads, and selected cities layers) from the Digital Chart of the World.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy was tested by manual comparison of the source with hard copy printouts and (or) symbolized display of the digital geologic data on an interactive computer graphic system. In addition, attributes were compared to a master set of valid geologic unit attributes.
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'" (Soller, 1992). 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).
Logical_Consistency_Report:
Topological accuracy was tested using topology validation tools via ArcGIS 9.3. Specific errors that were checked included polygon overlaps and gaps, coincident contact lines and geologic unit borders, self overlapping lines, and superfluous pseudo nodes. No duplicate features exist nor are there any duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Feature classes in the geodatabase are topologically clean.
Completeness_Report:
Data set complete. No data were intentionally omitted from the hard copy source map.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The location of geologic features in this database is derived from a conventionally compiled map that was prepared in the following manner. The map base was composed of 23 hand-mosaicked 4-degree by 6-degree 1:1,000,000-scale quadrangles from the International Map of the World Series (Lambert Conformal Conic projection) or the Army Map Service (Modified Polyconic projection of the International Map of the World). Relatively detailed source map information, in paper format, was photographically reduced to compilation scale (1:1,000,000) and visually registered to the base map using prominent cultural and topographic features. Owing to the generalized nature of any 1:1,000,000-scale base map, this was, in places, a difficult procedure, especially in areas of low topographic relief and sparse population. Each georeferenced source map was then interpreted and compiled into the final map. Lines and points were drawn on mylar, using a rapidograph pen, size 0000 (nominal width 0.18 millimeters). Although it is difficult to estimate horizontal positional accuracy for a regional map prepared in this fashion, it might be reasonable to assume a value of +/- 500 meters (essentially, 1 millimeter width on the map). These base maps were prepared and published over a span of many decades. The mosaicking was not flawless because of minor differences in the quality and size of available printing materials among the 23 quadrangles. Therefore, horizontal positional accuracy may be reduced along those quadrangle boundaries. As noted above, difficulties in visually registering source maps where the topographic relief is low and population is sparse resulted in a somewhat reduced horizontal positional accuracy in such areas.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 500 meters
Horizontal_Positional_Accuracy_Explanation:
Although it is difficult to estimate horizontal positional accuracy for a regional map prepared in this fashion, it might be reasonable to assume a value of +/- 500 meters (essentially, 1 millimeter width on the map).

Process_Description:
Source map information, in paper format, was photographically resized to compilation scale for interpretation and manual compilation. The map base was composed of hand-mosaicked 4-degree by 6-degree 1:1,000,000-scale quadrangles from the International Map of the World Series (Lambert Conformal Conic projection) or the Army Map Service (Modified Polyconic projection of the International Map of the World). To facilitate map printing, map data were divided into quadrangles for digitization, preparation of files in geographic information system format, and computer generation of printing negatives, according to techniques described in Soller and others (1990). To facilitate other uses for the digital map files, they were reprocessed as ArcInfo coverages, and published on CD-ROM (Soller and Packard, 1998).

Process_Description:
Original ArcInfo coverages were converted to file geodatabase feature classes. Coincident features were merged and dissolved along original quadrangle boundaries. Topological tests were run to determine inconsistencies in geometrical relationships within the dataset. Topological errors numbered in the thousands. Specific errors that were checked included polygon overlaps and gaps, coincident contact lines and geologic unit borders, self-overlapping lines and superfluous pseudo nodes, and duplicate features within a dataset. After topology was validated and cleaned, coded attribute information was replaced with free-text definitions. Feature class symbolization was created to closely resemble the printed version of the source maps. Finally, feature class symbology was exported to layer and style files.

Entity_Type:
Entity_Type_Label: Subsurface_selected
Entity_Type_Definition:
The distribution of selected subsurface Quaternary sediments, as shown on USGS Miscellaneous Investigations Series Map I-1970. In general, subsurface geologic units are not shown on this map because data are insufficient. In areas where a signficant subsurface unit is well known, the vertical succession of geologic units is depicted on the map in a generalized fashion, as a two-unit stack consisting of either the surficial unit and a well-mapped buried unit of some significance (for example, an aquifer) at some unspecified depth, or a discontinuous surface veneer of sediment and the underlying unit. These stack units include, but are not limited to, stratified sediments overlying till in a glacial lake basin, sand and gravel aquifers buried beneath till, and areas of peat or of eolian sediments (loess or eolian sand) capping older Quaternary sediments. These buried or veneer units are commonly widespread or thick and may be of economic as well as geologic significance (for example, as aquifers).

These two-unit stacks on the map do not portray the actual vertical succession of units. Where a buried coarse-grained stratified unit is depicted, it may occur at the base of section beneath till, or beneath till that contains numerous interbeds of stratified deposits and peat, or at some other position within the section, perhaps bounded above and below by till. However, the stack does indicate the occurrence of a well-known, significant buried unit. Also, where a veneer of loess is mapped over till, it is not implied that the entire section beneath the loess is till. Stratified deposits may be buried beneath or interbedded with till, as is certainly possible in areas where stack units are not shown.
