Continental drift is created at spreading centers, and this, along with subduction, drives the system of plates in a chaotic manner, resulting in continuous orogeny and areas of isostatic imbalance. The theory of plate tectonics explains all this, including the movement of the continents, better than Wegener's theory. Hans Stille and Leopold Kober opposed the idea of continental drift and worked on a "fixist" geosyncline model with Earth contraction playing a key role in the formation of orogens. Other geologists who opposed continental drift were Bailey Willis, Charles Schuchert, Rollin Chamberlin and Walther Bucher. In 1939 an international geological conference was held
Drift whale skulls - were used to ask for "whaling magic". The best known of these is the Yuquot Whalers Shrine, associated with the great Mowachaht chief Maquinna. The neighbouring Nuu-chah-nulth and Makah peoples used similar shrines to pull drift whales to them. proposed that drift whales might have formed a considerable summer food resource for people living on the coast of what is now Oregon, before contact with Europeans. Peoples that value whale meat and blubber have kept an eye out for drift whales, and traded the rights to them, for example bartering access to inland fishing rivers. Specific people may
