Surficial-geologic map of the Salcha River-Pogo area, Big Delta Quadrangle, Alaska
Description
Surficial-geologic map of the Salcha River-Pogo area, Big Delta Quadrangle, Alaska, Report of Investigation 2004-1C, illustrates the distribution of unconsolidated deposits and undifferentiated bedrcok units in the Salcha River-Pogo area. It was prepared by interpretation of 1:63,360-scale false-color infrared aerial photographs taken July 1978, July 1979, and August 1981, and is locally verified by ground observations during field visits. Based on the generally subdued nature of glacial deposits in the field area, we speculate that undifferentiated glacial deposits mapped are composed of material deposited by the Charley River (early? Pleistocene), Mt. Harper (middle? Pleistocene), and Eagle (early? Wisconsin) glaciations (Weber, 1986). It is highly unlikely that the area was glaciated during Salcha (late Wisconsin) or Ramshorn (Holocene) glaciations. The northeast-southwest-trending Shaw Creek fault crosses the study area. Although the fault was observed on 1:63,360-scale, false-color, infrared aerial photographs, we were unable to document offset on surficial geologic units. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: http://doi.org/10.14509/18001.
