Caldecott medalist Mordicai Gerstein captures the majestic redwoods of Yosemite in this little-known but important story from our nation's history. In 1903, President Theodore Roosevelt joined naturalist John Muir on a trip to Yosemite. Camping by themselves in the uncharted woods, the two men saw sights and held discussions that would ultimately lead to the establishment of our National Parks.
