Glaciation on the Arctic Slope of the Brooks Range, Northern Alaska

Reconstructs glacial history of the area (approx. 68-69 30 N, 147-162 W) on the basis of observations during 1944-1953 of the nature and extent of glacial deposits in the central part of the Range between Shainin and Itkillik Lakes and in the southern part of the Foothills Province from the Shaviovik River west to Etivluk River. Distribution is mapped and characteristics described of deposits from six glaciations for which a tentative chronological sequence is established: Anaktuvuk and Sagavanirktok of Pre-Wisconsin age; Itkillik and Echooka of Early Wisonsin; Alapah Mountain of Late Wisconsin; and Fan Mountain of Recent age. Terrace deposits and Pleistone alluviations are mentioned.
