Bruce Bjornstad has a new book, “Ice Age Floodscapes of the Pacific Northwest“, just released by publisher Springer. 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 the Ice Age floods was so huge that today it is often difficult to see the evidence 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 these Earth-changing events gathered by dozens of scientists since 1923.
