Delve into Jon Noad's analysis of why the flood occurred, its impact on specific settlements, and the geological evidence left behind. Gain insights into the Bow River Basin, the role of the jet stream, and the formation of debris flows. Examine case studies from Canmore and Calgary, including unseen aerial footage. Learn about sedimentological concepts such as crevasse splay deposits and river bend erosion.
