If you're not familiar with the Roadside Geology series, the next time you're planning a road trip, either close to home or farther afield, pick up the book covering the appropriate state. I would suggest that you read over the chapters covering the route you plan to take before you leave, or, at least, read about each day's itinerary the previous evening. When you hit the road, you'll know what you're looking at. It makes travel more interesting to realize that you're crossing a gigantic lava flow, or that the little ridge you just crossed is a dike of igneous rock thrust up between layers of sediments.
Last fall we dipped into the northwest corner of Arizona, from Sleeping Ute Mountain up in the Four Corners, down to Chinle and Canyon de Chelly. Lots of rocks, mountains, canyons, outcrops, and formations to see. Roadside Geology of Arizona is an excellent source for understanding why the scenery looks the way it does.
