The park became a wellspring of American art and conservation. Its waterfalls and granite walls drew generations of painters and photographers who fixed Yosemite in the national imagination, and the preservation argument that began here helped build the modern conservation movement. Today Yosemite spreads across roughly 748,000 acres of the Sierra Nevada, a UNESCO World Heritage Site since 1984, and draws three to four million visitors a year to a valley that, in its essentials, looks much as it did when Muir first walked in.
Then the country did something it had never done before. In 1864, in the middle of the Civil War, President Abraham Lincoln signed the Yosemite Grant, ceding Yosemite Valley and the Mariposa Grove to the State of California on the condition that they be preserved, unspoiled, for public use — the first time the United States set aside scenic land purely for preservation. It predated Yellowstone and the national-park system itself; in a real sense the idea of the national park was born here. Galen Clark, the valley's first appointed Guardian, looked after the grant in those early years.
Why People Visit Yosemite
Yosemite offers wilderness on a scale few places can match — a glacier-cut valley of granite cliffs and waterfalls, giant sequoias older than the country, and the high Sierra beyond, all carrying the founding story of the national-park idea. Visitors come for Half Dome, El Capitan, and the falls, and stay for the sequoias, the meadows, and the long Sierra light. From a valley stroll to the high country, it rewards a day or a week. It is timeless, humbling, and unmistakably California.
