Pleistocene Glaciation on St. George, Pribilof Islands

Abstract

A small ice cap (covering about 12 square kilometers) and at least two-probably four-cirque glaciers (each covering less than 1 square kilometer) occurred on St. George Island, Pribilof Islands, probably during the Illinoian; Glaciation. Snowbanks persisted during a later cold cycle, probably during the Wisconsin Glaciation, with no glaciers existing. We found no evidence of glaciation on other Pribilof islands.
