Description :
New radiocarbon dates on charcoal incorporated in proximal airfall deposits indicate the largest late Pleistocene eruption from the Mt. Edgecumbe volcanic field in Southeast Alaska occurred ca. 11,250 yr B.P. The more precise dating of the principal Edgecumbe tephra layer greatly improves its utility as a tephrochronologic marker horizon in southeastern Alaska.
