Excerpt from Interglacial Periods in CanadaThree great centres of accumulation of ice are recognized. The Cordilleran, shown by the late Dr. George M. Dawson to have come first, occupied the belt of mountains 400 miles wide forming the Pacific coast side of Canada. The summits of the higher peaks rose as nunataks above the ice, which crossed the straits of Georgia to the west and covered Vancouver island, but did not reach out over the prairies to the east except for a short distance at mountain passes, such as Bow river.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
