Sookhan et al.‘s paper consists of two parts: an analysis of glacial bedforms in the Seneca-Cayuga Finger Lake area and a paleoglacial history following the Valley Heads readvance. This comment concerns only the paleoglacial history. The biggest problem with their history is that a radiocarbon age was used for the Valley Heads readvance whereas a calendar age was used for the Bølling Allerød interstadial, leading to their erroneous conclusion that the entire Quaternary fill of the Cayuga trough was deposited in a single pulse lasting only a few hundred years. The duration between the Valley Heads readvance and the end of proglacial deposition there was actually about 4000 years. There are also serious questions concerning their descriptions of the nature of the deposits during and after the Valley Heads readvance. Sookhan et al.‘s claim of subaqueous and “chaotically-bedded outwash” is without any observational support. Because the prerequisites for their model of southward ice acceleration do not exist, that model is suspect and an alternative is suggested.
