Two highlands, the Candle Hills and Takotna Mountain, are surrounded by sediment-filled troughs of the Takotna, Tatalina, and Kuskokwim River valleys. Elevations range from 300 to 2,600 ft. This report is the result of 40 man-days of reconnaissance geologic mapping in 1977, 1978, and 1982. Bedrock exposures were mapped on foot and by boat. Four-fifths of the quadrangle is covered by Quaternary deposits, which have been subdivided on the basis of a photo-geologic reconnaissance and limited field checking. The report also includes detailed geologic, structural, stratigraphic, and geochronologic data. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2253.The investigation of gold and other mineral occurrences in conjunction with comprehensive geologic mapping provides a scientific basis for continued mineral exploration throughout project area.This geodatabase is organized according to the AK GeMS mapping schema Hendricks, M.D., Ekberg, P.G., Athey, J.E., Wyatt, W.C., Willingham, A.L., and Naibert, T.J., 2021, AK GeMS data dictionary: A description of the Alaska geologic mapping schema: Alaska Division of Geological & Geophysical Surveys Miscellaneous Publication 170, 10 p. https://doi.org/10.14509/30669.

Please contact us using the e-mail address provided above when possible.The geologic map database was converted to GeMS, quality controlled, and then finalized by DGGS staff Wes Buchanan, Ally Steinleitner, and DGGS contractors. Geologic map conversion to the GeMS standard was funded by the USGS National Cooperative Geologic Mapping Program under STATEMAP award number G21AC10706, 2022, and the State of Alaska General Fund. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the U.S. Government. The map and report were reviewed by M. S. Robinson and J,T. Kline, and the cartography was compiled by G.M. Lahd.Attribute fields within each feature class are populated using the map symbology and corresponding applicable values from the GeMS and AK GeMS specifications. When known, certainty in attribute interpretation is indicated in the relevant fields. Attribute accuracy varies throughout the map and is scale-dependent.All polygon features were topologically validated according to the AK GeMS geologic mapping schema specifications.This publication is a DGGS Professional Report (PR). A PR is the completed product of original research and analysis, and PRs use professional cartography and undergo rigorous peer review, editing, and revision.Certainty in feature boundaries or location varies throughout the map. Data fields within each feature class and the accompanying orientation and location confidence lookup tables record the authors' degree of confidence in the location of applicable features.Ekberg, P.G.Hendricks, M.D.Athey, J.E.2021AK GeMS symbology: A description of the AK GeMS style fileMiscellaneous PublicationMP 169Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys7 phttps://doi.org/10.14509/30584paper2021publication dateEkberg, P.G. and others, 2021GIS analysis and digital cartographyHendricks, M.D.Ekberg, P.G.Athey, J.E.Wyatt, W.C.Willingham, A.L.Naibert, T.J.2021AK GeMS data dictionary: A description of the Alaska geologic mapping schemaMiscellaneous PublicationMP 170Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys10 phttps://doi.org/10.14509/30669paper2021publication dateHendricks, M.D. and others, 2021GIS analysis and digital cartographyU.S. Geological Survey National Cooperative Geologic Mapping Program2020GeMS (Geologic Map Schema) - A standard format for the digital publication of geologic mapsTechniques and MethodsTM 11-B10United StatesU.S. Geological Survey1 phttps://dggs.alaska.gov/pubs/id/30585paper2020publication dateU.S. Geological Survey National Cooperative Geologic Mapping Program, 2020GIS analysis and digital cartographyGeologic mapping - DGGS conducted geologic field mapping of the bedrock units during 40 man-days of reconnaissance geologic mapping in 1977, 1978, and 1982. Bedrock exposures were mapped on foot and by boat. Four-fifths of the quadrangle is covered by Quaternary deposits, which have been subdivided on the basis of a photogeologic reconnaissance and limited field checking. Geologists recorded observations on 1:63,360-scale topographic base maps and/or similarly scaled aerial photographs. Field notes and rock samples were collected at stations throughout the map area. Geologists' observations were analyzed relative to the interpretations of previous workers and compiled onto a single mylar base map. Samples were collected for petrographic, age, and/or geochemical analysis. The publication received technical review and editing by several scientists familiar with the subject matter. The authors incorporated the reviewers' suggestions into the final draft.1982GIS analysis and digital cartography - This data distribution package's geologic and geographic features were organized and attributed according to the AK GeMS geologic mapping schema. The data were programmatically transformed to provide download options in three formats: (1) an AK GeMS data package that includes the complete AK GeMS database and associated files, (2) a GeMS data package that is a conversion of the AK GeMS database into the base GeMS standard published by the USGS, and (3) a shapefile data package that includes two simple shapefile representations of the data.Ekberg, P.G. and others, 2021Hendricks, M.D. and others, 2021U.S. Geological Survey National Cooperative Geologic Mapping Program, 20202022vectorUniversal Transverse Mercator50.999600-1530500000.0000000coordinate pair.00000001.00000001MetersNAD27Clarke 18666378206.4294.9786982mcgrath_d6_quad_ak_gems_db_pkgGeodatabase, layer files, style files, and fontsDGGSmcgrath_d6_quad_ak_gems_db_pkgmcgrath_d6_quad_gems_db_pkgGeodatabase, layer files, style files, and fontsDGGSmcgrath_d6_quad_gems_db_pkgmcgrath_d6_quad_gems_shapefile_pkgShapefiles and open data filesDGGSmcgrath_d6_quad_gems_shapefile_pkgAlaska Division of Geological & Geophysical SurveysMetadata Managermailing and physical
