John Muir took a camping trip in 1903 with President Theodore Roosevelt in Yosemite National Park, a preserve that Muir had lobbied congress to create in 1890. On that trip he convinced the president to take control of Yosemite Valley and Mariposa Grove away from California and return it to the federal government. In 1906, Roosevelt signed a bill that did precisely that.
