This guidebook explains the geological features of the Columbia River Basin in eastern Washington as regards the cataclysmic forces that formed them.

Author: Bruce Bjornstad
Softcover; 307 pages; black-and-white photos and charts
Keokee Co. Publishing Inc.; copyright 2006
Features explanations of 19 types of landforms and 70 flood-formed features
Also includes 30 off-road hiking and biking trails. 5 driving itineraries and 2 aerial tours

During the last great Ice Age some 15,000 years ago, the Pacific Northwest was repeatedly decimated by cataclysmic floods unlike anything in modern times. Giant walls of ice-laden water—miles wide and hundreds of feet deep— raced over the land at speeds up to 80 mph, scouring the landscape and leaving a fascinating geologic record. This book explores those legendary floods, explains the features they created, and guides readers to trails and tours in the Mid-Columbia Basin to witness the floods' awesome power for themselves.
