Items that have a triple line drawn along the left margin are good field trip localities. I am available to help run field trips to these or other areas. Call me. A friend Steve Bernier runs great bus tours.
I consider these diagrams I use for geo-education as cartoons, meant to convey ideas, not accurate depictions. A current book with lots of more accurate diagrams showing Southwest geologic development is Ron Blakey and Wayne Ranney's 'Geological History of the Colorado Plateau,' published by Grand Canyon Natural History Association, ~2005. Ron is (retired?) geo-professor from NAU Flagstaff. Wayne runs fantasy river trips down the Grand Canyon. We have done fieldwork along with Carol Hill, trying to piece together the origin of the Grand Canyon -- a sizable problem involving six western states. Their book contains many diagrams of out geologic history - the sea's advances, continental collisions -- the good stuff.
