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.Glacial epochNorthwest, PacificGlacial epoch551.792Bjornstad Bruce N.1081690MiAaPQMiAaPQUtOrBLWBOOK9910484813203321Ice Age Floodscapes of the Pacific Northwest2595683UNINA
