What is the Grant act?
On June 30, 1864, President Abraham Lincoln signed the Yosemite Valley Grant Act, Senate Bill 203. This Grant gave California the Yosemite Valley and the nearby Mariposa Big Tree Grove "upon the express conditions that the premises shall be held for public use, resort, and recreation.”
“Yosemite Valley, to me, is always a sunrise, a glitter of green and golden wonder in a vast edifice of stone and space.” ― Ansel Adams
