Glacial history (paleoglaciology)

Glaciers are sensitive to changes in climate, but even adjacent glaciers can respond differently to climatic forcing. Together with several international colleagues, I am working at several sites in British Columbia, Yukon, and Alaska to unravel the glacial histories of the areas based on radiocarbon dating of tree stumps, stratigraphic mapping, optically stimulated luminescence dating, and GIS-based hydrological modeling.
