Ice Age Floods National Geographic Trail

5/27/2010 Lewis and Clark National Historic Trail.

5/28/2010 Lake Roosevelt National Recreation Area. Joined the Columbia and in Coulee Dam (the town) stopped at Grand Coulee Dam [on the Ice Age Floods NGT]. Now, a channel carved by the racing waters is called a coulee, and the huge one carved by the flood is the Grand Coulee. [Grand Coulee NNL - an ancient river bed stretching for about 60 miles, created by volcanic activity and land periodically uplifting and subsiding] At the very impressive, very large dam, stopped at the interpretive center and saw a good film about the flood, and some exhibits. Sun Lakes Dry Falls State Park.
