On this day in 1864, President Lincoln signed the Yosemite Land Grant, protecting the Mariposa Grove and Yosemite Valley – an area that would later become Yosemite National Park. It was the first time the government protected land because of its natural beauty so that people could enjoy it. Thanks to John Muir’s passionate writing to further protect the delicate ecosystem of the High Sierra, Yosemite became our nation’s 3rd national park 26 years later.
