Geologist and author Bruce Bjornstad will present a bird's eye view of the Ice Age megafloods that impacted the Pacific Northwest as recently as 14,000 years ago and shaped the landscape of the mid-Columbia basin.

Bruce Bjornstad is a retired geologist with degrees from the University of New Hampshire and Eastern Washington University living in Richland, Washington.  During his career Bjornstad has written numerous documents and reports on the geology of eastern Washington as well as two geologic guidebooks "On the Trail of the Ice Age Floods" that tell of the transformation of the Pacific Northwest as recently as 14,000 years ago. Bjornstad is also the creator of an online YouTube Channel titled: “Ice Age Floodscapes”.  Most recently, Bjornstad has published a new, full-color, coffee-table-style book titled: “Ice Age Floodscapes of the Pacific Northwest: A Photographic Exploration”
