Yosemite Grant Act Legislation

Yosemite Grant Act 150th (1864-2014)

National Archives

Birth of the national park idea

On June 30, 1864, amid the civil war, President Abraham Lincoln signed the Yosemite Grant Act to protect Yosemite Valley and Mariposa Grove of Giant Sequoias. From the beginning this act was a legacy for our nation.

The story of Yosemite National Park's past, present, and future is one shared by many diverse cultures of people and is momentous to the birth of preservation. These anniversaries provide all Americans and the world a chance to increase our understanding of and dedication to the rich heritage of our national parks.

The program that we have put together with the communities that surround the park serves to honor our past and inspire people to experience, connect with, and protect our cultural and natural heritage. Learn how to get involved!
