The geology one can see from one of our Grand Canyon river tours is quite incredible. I have blogged about the rock layers and the easy way to help remember them all, but I have something new. I found this on the United States Geological Survey’s website and thought it was a great representation. A white water raft trip can be even more fun if you have some previous knowledge/interest in what you’ll be seeing!
