In 1903, President Theodore Roosevelt ditched his secret service detail to go camping in the woods of Yosemite with celebrated naturalist John Muir. Through his writings, Muir taught the importance of experiencing and protecting our natural world. That camping trip changed the face of conservation in the United States. Together, sleeping on the forest floor below the sequoias, they laid the foundation for the next century of federal land preservation.
