Bedrock geologic map of the Kigluaik Mountains, Seward Peninsula, Alaska

Bedrock geologic map of the Kigluaik Mountains, Seward Peninsula, Alaska, Public Data File 97-31, presents a 1:63,360-scale bedrock geologic map of parts of the Teller A-1, A-2, A-3, Nome D-1, D-2, D-3, Solomon D-6, and Bendeleben A-6 quadrangles. The Kigluaik Mountains comprise a region of rugged terrain located approximately 50 km north of Nome on the Seward Peninsula in northwestern Alaska and are defined as the topographic high between the Imuruk Basin on the north, the Sinuk River area to the south, the Nome-Teller highway to the west, and the Nome-Council highway to the east. This compilation at 1:63,360 scale is the first detailed map of the entire Kigluaik Mountains and has been compiled from geologic mapping at 1:24,000 scale as part of a project initiated by E. L. Miller at Stanford University in 1987. Our mapping covers more than 3/4 of the area of the Kigluaik Mountains, the rest of which was compiled from the aforementioned thesis maps and other sources. This mapping took place during field seasons of a duration of approximately 4-8 weeks a year during the years of 1989, 1990, 1991, and 1992. Field parties ranged in size from 1-5 persons, with minimal helicopter support. The aim of the project was to elucidate the Cretaceous tectonic history of the region, and as a result, Quaternary geology and minor offset faults were deemphasized. The Quaternary sediments of the region were mapped by Kaufman (1989). The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/1782.
