* Part of the popular Hiking Geology series * Appendices cover additional geologic information for the non-geologist * Everything needed to plan the trip, including information about permits, lodging and camping, mule rides, and recommended day trips Etched on the Grand Canyon's steep walls are stories of how this majestic landscape came to be: volcanic islands, stark deserts, and tranquil seas come and gone, and histories of plants and animals that have made this place their home. You'll see this story up close on the trail with the help of Hiking the Grand Canyon's Geology. In eighteen excursions, there's something for everyone-from the most popular rim-to-river trails (Havasu Canyon Trail) to gentle, half-day rim walks (Red Butte Trail) to rugged and remote multi-day backpack trips (Lava Falls Route). Geologists Lon Abbott and Teri Cook both teach at Prescott College in Prescott, Arizona, where they lead hiking trips to study geology in the field.
