Reconnassaince Topographic and Geologic Map of Grand Coulee Washington
Subject
Geology -- Grand Coulee (Wash.).
Description
This map was in The Grand Coulee by Bretz to illustrate his belief that the coulees in the region were created by a cataclysmic flood, as opposed to gradual processes, such as glaciation or wind erosion. The pink areas on the map illustrate a series of interconnected channels through which flowed the waters of a massive flood.
