Hiking Grand Canyon's Geology - $19.95

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). - $19.95
