We were fortunate on Monday that our flight from Los Angeles to Denver took us right over the Grand Canyon, the weather was fine, and we were sitting on the right side of the plane to get the best view. From 35,000 feet, it's impressive enough. Now I'm very motivated to see this up close. This is what happens to the Yampa River after it flows through Steamboat Springs, on to join the Green River and then the mighty Colorado River.
By the way, if you look closely at the horizon in the picture, you can see the curvature of the Earth. What a wonderful world we live in!
