Hiking the Grand Canyon's Geology

by Lon Abbott and Terri Cook
Seattle, WA: Mountaineers Books, 2004. 301 pages.

For the Hiking Geology series of The Mountaineers Books, Lon Abbott and Terri Cook have produced a hiker's guide to the Grand Canyon that explains the geology in loving expert detail, literally step by step. Eighteen excursions are detailed, ranging — as the publisher writes — "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)" and including useful information on permits, lodging and camping, and mule rides. The authors both teach at Prescott College, where they lead hiking trips to study geology in the field.
