During the three-year course of the program, geologists examined four districts that have contributed significantly to historical gold production in Alaska's Interior, Fairbanks, Livengood, Richardson, and upper Chena River. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/2315. The authors chose to study the upper Chena River district to better understand (1) the source of placer gold resources near Van Curler's Bar, (2) the nature and production potential of tungsten-bearing skarns in the eastern map area, and (3) a proposed route of a transportation corridor through the area. The Alaska legislature provided funding for the studies through capital and operating budget appropriations. Additional Acknowledgments: Geology by T.E. Smith, M.S. Robinson, F.R. Weber, C.F.

All polygon features were topologically validated according to specifications of the AK GeMS geologic mapping schema. This lineage was generated by the FGDC CSDGM to 19139 transformation Fieldwork - Mappers recorded observations in field notebooks and on the aerial photographs and topographic maps, predominantly at 1:63,360 scale. In some areas, photocopies of topography at varying enlarged scales were used. All compilations were made by hand on stable Mylar at 1:63,360 scale. Locations were determined visually in the field by reference to surrounding topography and sometimes by triangulation with Brunton compasses. 1983-01-01T00:00:00 Geologic map compilation - Data for the digital geologic map was digitized from a Mylar geologic field map compilation. This compilation was done on a one to one scale, stable Mylar of the USGS topographic base for each of the 1:63,360 scale USGS topographic bases included in the map area. The bedrock geologic map was compiled using field notes from fieldwork process step (above) and information from prior geologic investigations by various researchers.
