National Geographic Driving Guide to America, Rockies (NG Driving Guides)

This won't replace a guide with hotels and restaurants, but it's a terrific companion guide for doing the Rockies by car. It shows you how to Montana's Medicine Lake National Wildlife Refuge, home of one of the largest white pelican rookeries. It can also explain for you the bloody history of Idaho's White Bird Hill Battlefield as you drive past on U.S. 95 and perhaps turn off Wyoming's Route 120 for a rest in Thermopolis, with its hot mineral waters and cool shaded banks by the Bighorn River. The book's 160 pages include 150 color photos and maps, and 20 detailed driving itineraries.
