Sommario/riassunto |
|
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. |
