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 the distribution of a variety of unconsolidated deposits and undifferentiated bedrock in the Eagle A-2 Quadrangle, Fortymile mining district. It was prepared by the interpretation of 1:63,360-scale, false-color, infrared aerial photographs taken from July 1978 through August 1981 and is locally verified by ground observations during field visits. The results should be considered reconnaissance in nature. The dominant unconsolidated deposit is colluvium, which mantles most surfaces other than the tops of ridges and those areas immediately adjacent to streams. Three levels of stream terrace can be traced along major drainages at elevations of roughly 200, 100, and 30 meters above modern streams. A fourth low terrace is limited to the southwest part of the map area. Pleistocene mammalian remains have been recovered from ice-rich organic silt and muck overlying placer gravels in many valleys. Purpose: This project, resulting map, geospatial data are 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 have been reconnaissance-level maps or only covered portions of the quadrangle. Mapping at 1:63,360 scale (or more detailed) is needed to identify critical geologic features that may relate to more regional structures or geologic units. These detailed observations are also critical to test or use in tectonic models. This map also provides a geologic base in which to interpret geochemical results from the concurrent DGGS rock sampling program. Supplemental_Information: The layers listed below are present as ArcGIS shape files. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label." Basic unit information is also included in the unit code set file "PIR2001-3_codeset.pdf."

Geologic data included in the compilation are the field maps and notes from this project as well as photo interpretation of 1:50,000 (nominal) scale color-infrared aerial photographs and data from other sources as noted in the "Sources Cited" section. Logical_Consistency_Report: Polygon topology present. Polygon topology present on appropriate data; others are line, point, or annotation data and do not require topologic relationships. Completeness_Report: This data set includes geospatial data about geologic units, age and pingo locations. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Surficial mappers recorded observations on 1:50,000 scale (nominal) color-infrared aerial photographs and 1:63,360 scale topographic base maps. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 15 Horizontal_Positional_Accuracy_Explanation: Stations located using air photos and hand held GPS devices with location precision varying from +/-3 to 15 meters. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. "Selective availability," a deliberate degradation of GPS data managed by the U.S. government that induces an additional error of approximately 100 meters to a GPS location, was not in effect during this project's 2000 and 2001 field work.

Field notes and sediment samples were collected throughout the quadrangle for surficial investigations. Surficial mapping involved using Yeend (1996) on a regular basis for checking placer geology and general units. Surficial mappers recorded observations on 1:50,000 scale (nominal) color-infrared aerial photographs and 1:63,360 scale topographic base maps. Stations located using air photos and hand held GPS devices with location precision varying from +/-3 to 15 meters. Source_Used_Citation_Abbreviation: Yeend, 1996 Process_Date: 2000 Process_Step: Process_Description: Laboratory data compilation- Laboratory analyses were performed on radiocarbon samples and gold-bearing gravel samples from June 1999 intermittently through April 2001. Unanalyzed radiocarbon and tephra samples are currently stored at the DGGS office in Fairbanks. Final storage for most samples generated by this study will be at the DGGS Geologic Material Center (GMC) in Eagle River, Alaska. Process_Date: 2000 Process_Step: Process_Description: Geologic map compilation- Surficial geologic map was compiled using field notes from fieldwork process step (above), analytical results from laboratory data compilation process step (above), and all known geologic data from previous work in quadrangle. The main sources of existing data include Yeend (1996), Naeser and others (1982), and Werdon and others (2001). Geologic map contacts were delineated by photo interpretation of 1:50,000-scale color-infrared aerial photographs onto clear acetate overlays. The contacts were transferred from the overlays onto paper USGS 1:63,360 topographic base maps using a zoom transfer scope, and the contacts were then digitized using ArcEdit. Line work was edited using ArcEdit, and polygon topology generated and unit designations assigned using ArcInfo and ArcEdit. ArcPlot was used to generate plot files using DGGS-standard symbology, and the Arc graphics files were converted into .eps files for export to Adobe Illustrator for final cartographic assembly.
