Yosemite Valley
1864-1964

On June 30, 1864 the United States granted the Yosemite Valley and the Mariposa Big Tree Grove to the State of California to "be held for public use, resort and recreation...inalienable for all time." This act, signed by President Abraham Lincoln, was the first Federal authorization to preserve scenic and scientific values for public benefit. It was the basis for the later concept of state and National Park Systems. In 1906 the State of California returned the land, considered to the first State Park in the country, so that it could become part of Yosemite National Park.

Plaque placed by the California State Park Commission in cooperation with the California History Commission, and the National Park Service in commemoration of the 100th anniversary of the Yosemite grant. June 30, 1964.
