Abstract

Two sediment cores from Kaiyak and Squirrel lakes in north western Alaska yielded pollen records that date to ca. 39,000 and 27,000 yr BP, respectively. When compared to other pollen records from northwestern North America these cores (1) represent a meadow component of lowland, Beringian tundra between 39,000 and 14,000 yr BP (2) demonstrate an early Holocene arrival of Alnus in northwestern Alaska that predates most other Alnus horizons in northern Alaska or northwestern Canada, and (3) show an east-to-west migration of Picea across northern Alaska from 9000 to 5000 yr BP.
