We spent two days near Grand Coulee Dam. This area was shaped by volcanic lava flows followed by glacier melts of the Ice Age. Our campground, Sun Lakes RV Resort, is located in the valley of one of the coulees.
A coulee is a streambed, usually dried up, created by a lava flow and glacier melt. It is a steep-sided gorge. As we approached this area, it looked like gigantic mud cracks in the earth. The glacier flooding was so strong it carved out huge gouges in the earth. It was really amazing! 
This is Dry Falls, the skeletal remnants of the world's largest waterfall. It was created by catastrophic floods over Eastern Washington at the end of the Ice Age.
You can see all the different layers of rock formed centuries ago. I know that the bright greenish yellow color is lichen, but not sure what the other colors represent. There were also huge chunks of rock carried down by the ice and deposited all around.
The next day we drove to the Grand Coulee Dam which harnesses the Columbia River and provides irrigation, power and flood control.
