The deglaciation of North America had profound affects on climate, hydrology, flora, humans, and megafauna. Pollen records have traditionally been the primary source of information about environmental change during deglaciation, but tree rings offer potential for insight into high-resolution variability of weather/climate during this period. Wood preserved in the Great Lakes area by various fortuitous circumstances has been systematically collected over the last decade to improve our environmental understanding of the period from ca. 14,000 to 6000 years ago. Dozens of chronologies have been developed, and this presentation highlights the project and findings to date.
