The story of Yosemite National Park's past, present, and future is one shared by many diverse cultures of people and is momentous to the birth of preservation. These anniversaries provided all Americans and the world a chance to increase our understanding of and dedication to the rich heritage of our national parks.

August 25, 2015: Yosemite Turns 125!
On October 1, 2015, the park commemorated the 125th anniversary of the establishment of Yosemite National Park. President Benjamin Harrison signed the legislation, thereby creating the nation's third National Park. The establishment of Yosemite National Park preserved over 1,500 square miles of land including Tuolumne Meadows, the park's high country, Hetch Hetchy and lands surrounding Yosemite Valley.
The creation of Yosemite National Park added protected land to the existing Yosemite Grant Act of 1864. This landmark law protected Yosemite Valley and the Mariposa Grove of Giant Sequoias and was managed by the State of California. Preservation of these lands is generally regarded as the birth of the national park idea. The creation of the park and the Yosemite Grant collectively preserved most of Yosemite National Park as it is known today.
September 3, 2014: 50th Anniversary of the Wilderness Act
On September 3, 1964 President Lyndon B. Johnson signed into law the Wilderness Act. This historic bill established the National Wilderness Preservation System (NWPS) and set aside an initial 9.1 million acres of wildlands for the use and benefit of the American people. Over the past 50 years, and as a result of America's support for wilderness, Congress has added over 100 million acres to this unique land preservation system. The 1964 Wilderness Act defines "Wilderness" as areas where the earth and its communities of life are left unchanged by people, where the primary forces of nature are in control, and where people themselves are visitors who do not remain.
