The area is part of the Manley Hot Springs-Tofty mining districts and adjacent to the Rampart mining district to the south of the Tanana B-1 Quadrangle. This report includes detailed surficial, structural, stratigraphic, and paleontologic data. Based on the resulting geologic maps, field investigations, and laboratory materials analyses, the report also includes derivative maps of geologic construction materials and geologic hazards. The Tanana A-1 and A-2 Quadrangles and surrounding area comprise several isolated mountainous ridges in the western Yukon-Tanana Upland of interior Alaska. Purpose: The Tanana A-1 and A-2 Quadrangles lie between the villages of Rampart, on the Yukon River, and Manley Hot Springs, at the terminus of the Elliott Highway. At the time the report was published, the area towns were not part of any municipal or local governmental jurisdiction. The investigation of gold, tin, and other mineral occurrences in conjunction with comprehensive geologic mapping and recently-acquired geophysical data will provide a scientific basis for expanded mineral exploration and development that can lead to the economic growth and the creation of new jobs needed by the Rampart-Manley-Tofty region's inhabitants and the State of Alaska. These objectives are consistent with the statewide goals and priorities articulated for the Department of Natural Resources by Alaska's Governor in his Executive Budget Summary for Fiscal Year 1997.

Geologic data included in the compilation are the field maps and notes from this project as well as data from other sources as noted in the "Sources Cited" section. Attributes were verified for consistency and completeness during the creation of the metadata. Logical_Consistency_Report: Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships. Completeness_Report: This dataset includes geospatial information about geologic units, their ages, fossil, and field sample locations, structural features, surficial features, and structural measurements. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: DGGS location data and estimated position errors were manually entered into a spreadsheet. Sample numbers and locations with selected data were spatially registered and analyzed in ArcGIS software. Location data for the surficial and materials maps were determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, color-infrared aerial photographs. See "Source_Information" section for horizontal positional accuracy of locations not measured by DGGS. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 100 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by the GPS units and recorded for each sample location. 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 in effect until May 1, 2000, and thus during the time of this field work. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 110 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters. Surficial and engineering-geologic map data have a horizontal positional accuracy dependent on: 1) the 1:50,000-scale (nominal) aerial photographs on which it is based, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; 2) the accuracy of the human zoom transfer scope operator in tracing the line work from acetate overlays to topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; 3) the accuracy of the zoom transfer process itself, error magnitude highly variable and unknown but potentially large; 4) the digitizing RMS error of 0.003 inches (input coverage units), which equates to approximately 5 meters on the ground for a 1:63,360-scale map; and 5) the accuracy of the human operator digitizing the geologic line work from the topographic base maps, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground. Total potential horizontal error for surficial-geologic map features is therefore estimated to be approximately 110 meters. The surficial and engineering field maps were digitized using a map tablet and cross-hair mouse. Map error is induced by: (1) transferring map data from base topography to a mylar compilation map, with an estimated potential error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground; (2) the digitizing RMS error [24 control points on a regular grid have an average RMS error of 10.8 meters on the ground; individual control point error ranges from 4.3 to 21.2 meters on the ground]; and (3) the accuracy of the human operator digitizing the geologic line work from the topographic base map, with an estimated error due to a pen line width of approximately 0.001 being equivalent to approximately 1.5 meters on the ground.

Process_Step: Process_Description: Fieldwork - Fieldwork for surficial geologic investigations, including ridge and valley traverses, roadcut investigations, and river exposures, was conducted for approximately 21 person-days in June and July 1997 by a surficial geologist. Field notes and sediment samples were collected throughout the area for surficial investigations. Surficial mapping involved using sources cited below on a regular basis for checking and correlating general units. Surficial mapper recorded observations on co-registered acetate overlays on 1:50,000-scale (nominal) color-infrared aerial photographs, and directly on 1:63,360-scale topographic base maps. Stations were located using air photos and topographic maps.

Photo interpretation was based on field notes from fieldwork process step (above), observed land forms and relationships in the photos, and all known geologic data from previous work in the area. The main sources of existing data include Eakin (1912; 1913), Hopkins and Tabor (1962), and Yeend (1989). The overlay information was transferred to a paper 1:63,360-scale USGS topographic base using a zoom transfer scope.

Surficial-geologic polygons and lines were then edited and attributed using Arc, Info, and ArcEdit. Bedrock point data of locations of structural observations (strike, dip, cleavage, jointing, etc.) were intersected with the surficial-geologic polygon coverage using the Arc command "intersect" in order to identify locations that were mapped as surficial materials based on aerial photography but were found to have small exposures that were desirable to be mapped as bedrock. These areas were then modified in the surficial-geologic coverages to be areas of bedrock exposure. Final bedrock and surficial geology polygon coverages were merged using the Arc command "union" to generate the polygon coverage used to make the comprehensive geologic map. Other cartographic elements, primarily text and tables, were created in CorelDraw, converted to CGM format, and imported into ArcPlot for final layout. Data from the comprehensive geologic map of the area were used as the basis for generating the derivative engineering-geologic map. 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 (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". Additional features were mapped from ground observations and interpretation of air photos, and digitized and attributed using ArcInfo. ArcPlot was used to generate plot files of the resulting materials coverage using DGGS-standard symbology.
