I strongly endorse this article and all of the reasons given by the author:

I myself never took geology, but I wish I had. And, now, whenever I visit Hawaii or Yellowstone or wherever, I commonly buy (and use) a simple book on the local geological features and their history. And, when my wife and I drive long distances, we commonly have a copy of The Roadside Geology of Utah or The Roadside Geology of Wyoming or The Roadside Geography of Arizona (or some such title) with us.
A last note: If you live in the areas of historically rather dense Mormon population (Utah, Idaho, Wyoming, Arizona, perhaps western Colorado) — or if you have occasion to visit them — you shouldn’t pass up the chance to see, and to learn about, one of Earth’s most extraordinary concentrations of geologically interesting places. Yellowstone, the Grand Canyon, Zion, Bryce, Craters of the Moon, the Grand Tetons, Canyonlands, Arches, the Black Canyon of the Gunnison, Rocky Mountain National Park, Cedar Breaks, Snow Canyon, Lake Powell . . . the riches are inexhaustible, and often both dramatic and stunningly beautiful.
