“The Kaska people of western Canada, for instance, have the following story (condensed from Teit 1917: 442–3):
“Once there came a great flood, which covered the earth. The people became separated. Some were driven far away. When the flood subsided, people were now widely scattered over the world. When, in their wanderings, they met people from another place, they spoke different languages and could not
understand one another. This is why there are now many different centres of population, many tribes, and many languages. Before the flood there was but one centre, for all the people lived together in one country and spoke one language.”
