On October 1, 1890, an act of Congress creates Yosemite National Park, home of such natural wonders as Half Dome and the giant sequoia trees. Environmental trailblazer John Muir (1838-1914) and his colleagues campaigned for the congressional action, which was signed into law by President Benjamin Harrison and paved the way for generations of hikers, campers and nature lovers, along with countless “Don’t Feed the Bears” signs.
Native Americans were the main residents of the Yosemite Valley, located in California’s Sierra Nevada mountain range, until the 1849 gold rush brought thousands of non-Indigenous miners and settlers to the region. Tourists and damage to Yosemite Valley’s ecosystem followed. In 1864, to ward off further commercial exploitation, conservationists convinced President Abraham Lincoln to declare Yosemite Valley and the Mariposa Grove of giant sequoias a public trust of California. This marked the first time the U.S. government protected land for public enjoyment and it laid the foundation for the establishment of the national and state park systems. Yellowstone became America’s first national park in 1872.

In 1889, John Muir discovered that the vast meadows surrounding Yosemite Valley, which lacked government protection, were being overrun and destroyed by domestic sheep grazing. Muir and Robert Underwood Johnson, a fellow environmentalist and influential magazine editor, lobbied for national park status for the large wilderness area around Yosemite Valley. On October 1 of the following year, Congress set aside over 1,500 square miles of land (about the size of Rhode Island) for what would become Yosemite National Park, America’s third national park. In 1906, the state-controlled Yosemite Valley and Mariposa Grove came under federal jurisdiction with the rest of the park.
Yosemite’s natural beauty is immortalized in the black-and-white landscape photographs of Ansel Adams (1902-1984), who at one point lived in the park and spent years photographing it. Today, over 3 million people get back to nature annually at Yosemite and check out such stunning landmarks as the 2,425-foot-high Yosemite Falls, one of the world’s tallest waterfalls; rock formations Half Dome and El Capitan, the largest granite monolith in the U.S.; and the three groves of giant sequoias, the world’s biggest trees.
