Quaternary stratigraphic sections with radiocarbon dates, Chandalar Quadrangle, Alaska

Surficial geologic mapping of the Chandalar quadrangle was carried out during 1975 and 1976 as part of the Arctic Environmental Program of the U.S. Geological Survey. Ten organic samples were collected at that time for radiocarbon dating. Six samples have been dated by Stephen W. Robinson at the U.S. Geological Survey Radiocarbon Laboratory in Menlo Park, California, and one additional sample was dated by Isotopes, Inc. (table 1 and plate 1). The three remaining samples will be dated by Isotopes, Inc. during the winter of 1979-1980. The surficial geologic map of the Chandalar quadrangle (Hamilton, 1978a) should be referred to for geologic units and relationships discussed in the following sections.
