Late Pleistocene glacial chronology of north-central Brooks Range, Alaska

Abstract

Stratigraphic sections and radiocarbon dates serve as a basis for defining four substages in the late Pleistocene Itkillik glaciation which are correlated with the four substages of the Wisconsin glaciation of central North America. Three post-Itkillik advances, restricted to the highest parts of the range, are correlated with post-hypsithermal advances elsewhere in the North American Cordillera.
