Summary: | Many fundamental problems exist in comparing the chronology and correlation of Late Pleistocene glaciations between Western and Eastern Beringia. However, geomorphological analysis, complemented by palynological studies and radiocarbon age estimates of glacial complexes found in the Ulakhan-Chistai, Bolshoi Annachag, and Pekulney ranges, northeastern Russia, and the Kigluaik Mountains and Brooks Range, Alaska, allow for broad comparisons. The data clearly con"rm that in all regions the latest late Pleistocene glaciation (24.0}10.5 ka) was restricted in extent and characterized by well-de"ned valley glaciers and coalescing valley glacier complexes emanating from local mountain centers. Di!erences in glacier size were due to local orographic and climatological
