The goal of this cooperative project is to document the former high stands and assess the stability of the West Antarctic ice sheet at the Ohio Range near the head of the Mercer Ice Stream. The field location is situated in the "Bottleneck", a unique, reatively narrow passage in the Tansantarctic Mouintains connecting the West and East Antarctic ice sheets. This research will involve geologic mapping of glacial deposits combined with comogenic surface exposure age dating.
