On June 30, 1864, 152 years ago today, President Abraham Lincoln signed an act “authorizing a grant to the State of California of the Yo-Semite Valley, and of the land embracing the Mariposa Big Tree Grove.” Under the Yosemite Grant, scenic natural areas were set aside and protected for the benefit of future generations for the first time in the history of our nation.
