Abstract

The climate of the glacial boundary during the Wisconsin maximum was generally cooler and moister than at present. There is some evidence that a frost climate prevailed for some time at the glacial margin, suggesting that a tundra-like vegetation existed there. Pollen profiles indicate that a Picea-Abies forest existed south of the glacial margin and probably extended up to it during periods of climatic amelioration.
