- About this book
-
This heavily illustrated book contains descriptions and geologic interpretations of photographs (mostly aerial) illustrating the power and magnitude of repeated Ice Age flooding in the Pacific Northwest, as recently as 14,000 years ago. The scale of Ice Age floods was so huge that today it is often difficult to see and appreciate the power and magnitude of such megafloods from ground level. However, from the air, landforms created by the floods often come into clear focus. Aerial images, obtained via unmanned aerial vehicle (drone) as well as fixed-wing airplane, add a new perspective on evidence gathered by dozens of scientists since 1923.

Bruce Bjornstad has 40 years’ experience working as a professional geologist/hydrogeologist. After receiving his master's degree in geology in 1980 he started his career working for Rockwell Hanford Operations to characterize a proposed high-level nuclear-waste repository near Richland, WA. In 1990, Bjornstad went to work at Battelle's Pacific Northwest National Laboratory doing environmental clean-up and restoration at the nearby Hanford Site. During this time Bjornstad published dozens of technical publications along with two geologic guidebooks on Ice Age megafloods that transformed the region as recently as 14,000 years ago. In retirement, Bjornstad continues his work on Ice Age megafloods, including an online YouTube channel: Ice Age Floodscapes. In his free time Bjornstad enjoys skiing, hiking, and exploring his Northwest surroundings.
