Another beautiful day. In fact it was a dam nice day. We drove north about 75 miles to the Grand Coulee Dam. On the way we stopped at the worlds largest dry waterfall. About 13,000 years ago when the glaciers melted there was a waterfall here over 3 miles wide and about 900 feet tall which formed much of WA, ID & MT. The glaciers backed up several rivers for decades until they burst through the glaciers. This happened dozens of times.
We were both surprised to see the geography which is desert and tall cliffs, not many trees and no forests. Reminds us of the Grand Canyon.
The dam is one mile long and almost as tall underwater as it is above. We took the dam tour and at the visitor center watched a video of it's construction. After dark there is a laser light show projected on the dam (worlds largest screen) but we didn't want to wait 5 hours until 10pm.
