Sunday, June 30, marks the 155 anniversary of the Yosemite Valley Grant Act.
On June 30, 1864, President Abraham Lincoln signed the act that gave the state of California ownership of the valley under the condition that is ‘shall be held for public use, resort, and recreation.’
Conservationist John Muir felt Yosemite’s protected status was not enough- and lobbied, helping lead Yosemite to become a national park in 1980. Thirteen years later, in 1903, Muir famously led President Theodore Roosevelt on a tour.
Since then millions of other visitors have followed in their footsteps to explore the many natural wonders within Yosemite National Park.
