Day Hikes from the River: A Guide to 75 Hikes from Camps on the Colorado River in Grand Canyon National Park
Tom Martin has been hiking in Grand Canyon from river rafting trips since 1969. He has participated on scientific rafting trips as a field technician, worked as a commercial river guide, and participated on private rafting trips. With four first ascents through the Redwall Limestone and numerous ascents of Grand Canyon named buttes in day hikes from the river, the author has hiked enough of Grand Canyon to be able to say "Of the cat that is Grand Canyon, I have seen one hair." Tom co-founded the Grand Canyon Private Boaters Association, and currently works as a physical therapist at the Grand Canyon Clinic.
