Castleguard 2020: Highlights & Screwups – by Katie Graham

Join us for a presentation by one of our northern neighbors, Katie Graham! She will be taking us on a journey to the longest cave in Canada, which also happens to extend underneath a glacier. According to the Encyclopedia of Caves (2019), “It displays many striking features of interactions between glaciers and karst aquifers, a complex modern climate, rich mineralization, and a troglobitic fauna that has possibly survived one or more ice ages beneath deep ice cover in the heart of the Rocky Mountains.”
