Before there were national parks, Yosemite Valley was a vast wilderness, home to giant sequoias and majestic redwoods - and the famous naturalist John Muir wanted to keep it that way. He was afraid of what would happen if our nation's wilderness areas went unprotected. In 1903 he invited President Theodore Roosevelt to join him on a California camping trip to discuss the impending crisis. Here, with glorious illustrations, is the little-known story of that momentous excursion - and how it forever changed the face of our nation's landscape. Hardcover. 32 pgs.
