A fireside presentation

My talk at the Visitor Center in February, 2020 explored the past 20,000 years of glaciation and sea level change in northern Southeast Alaska—and the light this history sheds on human cycles of invasion and residence in the archipelago. Examples came from work with local Áak’w Kwáan glaciers, but also Glacier Bay and the Chilkat country. Three iconic species—harbor seal, sockeye salmon and redcedar—so important to Northwest culture, each have responded differently to ecological disturbance and stability. We used these species to bridge between glacial and human histories.
