From the author of such travel adventure classics as Jaguars Ripped My Flesh and Road Fever, comes an informative and entertaining travelogue through one of America's favorite destinations: Yellowstone National Park. On his several-hundred-mile trek across the wilderness, the author explores such natural wonders as glaciers and geysers, muses about the microbiology of thermal pools, and witnesses moonbows arcing across waterfalls at midnight. Inevitably, he runs into Yellowstone's various inhabitants, including a grizzly bear with a footprint "about the size of a pizza", and others he had previously seen only on television.
