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. 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.

All polygon features were topologically validated according to the AK GeMS geologic mapping schema specifications. This lineage was generated by the FGDC CSDGM to 19139 transformation Geologic 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. 1982-01-01T00:00:00 GIS 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. 2022-01-01T00:00:00 Source Contribution: GIS analysis and digital cartographySource Type: paper AK GeMS symbology: A description of the AK GeMS style file 2021-01-01 publication Alaska Division of Geological & Geophysical Surveys Fairbanks Alaska, United States publisher Ekberg, P.G. originator Hendricks, M.D. originator Athey, J.E. originator https://doi.org/10.14509/30584 Miscellaneous Publication MP 169 7 p 2021-01-01 Source Contribution: GIS analysis and digital cartographySource Type: paper AK GeMS data dictionary: A description of the Alaska geologic mapping schema 2021-01-01 publication Alaska Division of Geological & Geophysical Surveys Fairbanks Alaska, United States publisher Hendricks, M.D. originator Ekberg, P.G. originator Athey, J.E. originator Wyatt, W.C. originator Willingham, A.L. originator Naibert, T.J. originator https://doi.org/10.14509/30669 Miscellaneous Publication MP 170 10 p 2021-01-01 Source Contribution: GIS analysis and digital cartographySource Type: paper GeMS (Geologic Map Schema) - A standard format for the digital publication of geologic maps 2020-01-01 publication U.S. Geological Survey United States publisher U.S. Geological Survey National Cooperative Geologic Mapping Program originator https://dggs.alaska.gov/pubs/id/30585 Techniques and Methods TM 11-B10 1 p 2020-01-01 otherRestrictions Metadata Use Constraints: If the user has modified the data in any way they are obligated to describe the types of modifications they have performed in the supporting metadata file.
