Winner of the 2010 National Outdoor Book Award for Children's Literature! What happened when President Theodore Roosevelt went camping in California's Yosemite wilderness with naturalist John Muir in 1903? While enjoying the wonders of this magical place, they talked about birds, giant sequoia trees and glaciers, as well as the importance of preserving wilderness for future generations. Later, President Roosevelt set aside additional national parks, added land to Yosemite National Park, and created monuments as a direct result of this historic camping trip.
