This geologic map and report supersede the previously released Public Data File 99-24C, Preliminary surficial-geologic map of the Healy A-6 Quadrangle, southcentral Alaska. The current map has been updated to include mapping of areas adjacent to the Healy A-6 Quadrangle. Field investigations were part of a two-year mapping program to provide geologic ground truth for airborne geophysical surveys flown by DGGS in the Chulitna region of southcentral Alaska during 1996. Purpose: The purpose of this project was to produce a 1:63,360-scale geologic map for the airborne geophysical surveys released by DGGS in the Chulitna region during 1996. The geologic data are important for identifying potential mineral deposits and for characterizing and distinguishing between geologic units.

The surficial-geologic information was transferred from acetate air-photo overlays to a paper 1:63,360-scale USGS topographic base using a zoom transfer scope. The surficial-geologic information was then digitized into Arc/Info GIS (ArcEdit module) using a large-format digitizing table with RMS registration errors constrained to be no larger than 0.003 inches (input coverage units) for each digitizing session. 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. Logical_Consistency_Report: Polygon topology present and clean on appropriate data; others are line or point data. Completeness_Report: This dataset includes geospatial information about geologic units and land forms. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were determined visually using topographic maps at a scale of 1:63,360 and 1:50,000 (nominal) scale, color-infrared aerial photographs. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 10 Horizontal_Positional_Accuracy_Explanation: Approximate error in meters. Surficial-geologic map data have a horizontal positional accuracy dependent on: (1) the 1:50,000-scale (nominal) aerial photographs on which they are 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 10 meters.

See this publication cited in the Process Step section below. Process_Step: Process_Description: Fieldwork - Fieldwork for geologic investigations, including ridge and valley traverses, road cut investigations, and river exposures, was conducted for approximately seven person-days in June 1997 by a surficial geologist. Field notes and sediment samples were collected throughout the area for surficial investigations. Surficial mapping involved using Reger and Pinney (1996), Ten Brink (1983), and Wahrhaftig (1958) 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. Source_Used_Citation_Abbreviation: Reger and Pinney, 1996 Source_Used_Citation_Abbreviation: Ten Brink, 1983 Source_Used_Citation_Abbreviation: Wahrhaftig, 1958 Process_Date: 1998 Process_Step: Process_Description: Photo interpretation - Before, during, and after fieldwork, surficial-geologic information was interpreted using 1:50,000-scale (nominal) color-infrared air-photo stereopairs, and compiled onto acetate overlays. 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 Reger and Pinney (1996), Ten Brink (1983), and Wahrhaftig (1958). The overlay information was transferred to a paper 1:63,360-scale USGS topographic base using a zoom transfer scope. Process_Date: 1998 Process_Step: Process_Description: Digital cartography - Surficial-geologic information was digitized from the paper USGS topographic base map (above) into Arc/Info 7.0.4 GIS (ArcEdit module) using a large-format digitizing table. 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 RI 2001-1B, the comprehensive geologic map.
