The area is part of the 100-year old Fortymile mining district and is located in eastern Alaska near the Alaska-Yukon border. This map illustrates potential near-surface sources of various geologic materials that may be useful for construction. Field observations indicate that each geologic unit (for example, stream alluvium) has a definite composition or range of composition. Therefore, the probable presence of materials is interpreted from the distribution of geologic units on the geologic map of this quadrangle. This map is generalized and is not intended to show exact locations of specific materials. Local variations are common, especially near unit boundaries. The map was derived electronically from the geologic map of the area using Geographic Information System (GIS) software. It is locally verified by ground observations during field visits. The results should be considered reconnaissance in nature. Purpose: This project, resulting map, geospatial data was intended to provide a geologic map and a geologic interpretation of the Fortymile mining district at 1:63,360 scale. Previous published 1:63,360 scale geologic maps of this area were reconnaissance-level maps or only covered portions of the quadrangle. Mapping at 1:63,360 scale (or more detailed) was needed to identify critical geologic features that may relate to more regional structures or geologic units. Supplemental_Information: The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships. Attribute information for the layers (entity) is included in this metadata file under the "Entity_and_Attribute_Information" section. The layers are titled: >border: outline shape of the study area >contact: engineering-geologic unit outlines >materials: engineering-geologic units >photolinear: linear features visible on aerial photographs >pingo: pingo locations Time_Period_of_Content: Time_Period_Information: Multiple_Dates/Times: Single_Date/Time: Calendar_Date: 2001 Single_Date/Time: Calendar_Date: 2002 Single_Date/Time: Calendar_Date: 2012 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -141.50 East_Bounding_Coordinate: -141.00 North_Bounding_Coordinate: 64.25 South_Bounding_Coordinate: 64.00 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Theme_Keyword: Alluvial Deposits Theme_Keyword: Alluvium Theme_Keyword: Colluvial Deposits Theme_Keyword: Colluvium Theme_Keyword: Construction Materials Theme_Keyword: Crushed Gravel Theme_Keyword: Crushed Rock Theme_Keyword: Decorative Stone Theme_Keyword: Drain Rock Theme_Keyword: Engineering Theme_Keyword: Engineering Geology Theme_Keyword: Geologic Hazards Theme_Keyword: Geologic Map Theme_Keyword: Geologic Materials Theme_Keyword: Ground Ice Theme_Keyword: Permafrost Theme_Keyword: Photogeologic Lineaments Theme_Keyword: Pingos Theme_Keyword: Rip Rap Theme_Keyword: STATEMAP Project Theme_Keyword: Sand and Gravel Theme_Keyword: Thawing Permafrost Theme_Keyword: Unconsolidated Deposits Place: Place_Keyword_Thesaurus: Alaska Division of Geological & Geophysical Surveys Place_Keyword: Boundary (Place) Place_Keyword: Fortymile Mining District Place_Keyword: Jack Wade Junction Place_Keyword: Steele Creek Dome Place_Keyword: Taylor Highway Place_Keyword: Top of the World Highway Place_Keyword: Walker Fork Access_Constraints: This report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

The geologic unit interpretations and boundaries presented in this report result from interpretation of nominal 1:65,000-scale aerial photographs, investigative traverses throughout the map area, aerial reconnaissance via helicopter, and examination of road-cuts and river exposures. Engineering-geologic map units were derived from the surficial-geologic map (PIR 2002-3C). Physical properties of engineering-geologic map units are interpretive, based on extrapolation from verified localities and from previously published reports and data. This map has received two technical reviews by scientists familiar with the subject matter. We incorporated the reviewer's suggestions into the final draft. Logical_Consistency_Report: Polygon topology was present and clean on the original Arc GIS coverages. All polygon features were topologically validated using ArcGIS prior to export to shapefile format. Completeness_Report: This dataset includes shapefiles that contain information about the mapped and interpreted engineering-geologic deposits in the map area distinguishable at a scale of 1:63,360. No analytical tests were conducted for this report. The table describes engineering properties that are generally present in the mapped surficial deposits, but local variations and exceptions are most certainly to be expected. The reader is therefore cautioned that this map is intended only as a general guide, and that unevaluated geologic resources and hazards may be present. Detailed geotechnical investigations should be conducted prior to utilization of any map units for engineering purposes. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Surficial mappers recorded observations on 1:65,000-scale (nominal) color-infrared aerial photographs and 1:63,360 scale topographic base maps. We believe the total horizontal accuracy of the mapped surficial-geologic contacts is on the order of 25 m or better, with somewhat lesser accuracy expected in areas of rugged relief.

An ArcInfo lookup table was made to assign geologic units (item UNIT) from the comprehensive map to appropriate engineering-geologic units (item MAT) based on the Unified Soil Classification System as described by Wagner, A.A., 1957. This lookup table was applied to the ArcInfo polygon coverage containing the geologic units and a new engineering-geologic polygon coverage was generated using the "dissolve" command based on the new materials-unit item "MAT". ArcPlot was used to generate plot files of the resulting materials coverage using DGGS-standard symbology, and the Arc graphics files were converted into .eps files for export to Adobe Illustrator for final cartographic assembly.

At the time of publication, DGGS staff converted the originating ArcInfo coverages to shapefiles, compiled FGDC compliant metadata documentation, and assembled the shapefiles into an online data distribution package.
