About Yosemite Anniversary Team

As you may know, we are in the midst of several anniversaries…


Yosemite Grant Act 1864-2014
Yosemite has inspired generations of people for thousands of years. On June 30, 1864, Congress enacted the Yosemite Grant Act, establishing Yosemite Valley and Mariposa Grove as the first protected wild land for all time. This grant marked the first California State Park.

In 1890, the land surrounding these two tracts was designated Yosemite National Park. Early conservationist John Muir’s persuasive words to President Roosevelt and state authorities led to combining Yosemite Valley and Mariposa Grove with Yosemite National Park in 1906.

We will honor the 150th anniversary in 2014 through events, programs and official merchandise found throughout the communities surrounding the park. In fact, 90% of these projects will be hosted in the gateway communities. You can be a part of this monumental anniversary!

Our team consists of 85 volunteers, all of our park partners, California State Parks, and National Park Service staff. We have a mosaic of backgrounds and interests — with Yosemite at our core.


In early 2011, Yosemite’s partners collaborated to define how we could collectively honor Yosemite’s rich history. Since this was the first major project in which all park partners were at the table for, our community-partnership Anniversary Program pulled from existing and relevant park documents to identify guiding principles. In addition, acknowledging that we would need to be a networked organization, we identified our mission alignment.


Our Partner Mission Alignment
The park has both formal and informal partners. Partner organizations’ mission statement commonalities:

  • Visitor enjoyment and guest hospitality.
  • Education and learning experiences.
  • Stewardship of natural, historic, and cultural resources and heritage.
  • Conservation for future generations.

California State Parks 

California State Parks and the National Park Service are commemorating their joint heritage at Yosemite.  The State of California owned and managed Yosemite Valley and the Mariposa Grove as state parks from 1864 until these areas were returned to the Federal Government in 1906, to become part of the larger Yosemite National Park, established in 1890.

In 2014, California State Parks turns 150 years old!

California State Parks commemorates the 1864 establishment of the first state park in the world. On June 30, 1864, President Abraham Lincoln signed a bill granting 39,000 acres of Yosemite Valley and the Mariposa Big Tree Grove to the State of California. Never before had land been set aside to protect its natural state for the public to enjoy. This historic legislation was the beginning of not only the California State Park System, but the national park idea we know today.

As we commemorate our 150th birthday next year, we will be adding information, so please check back to see what is new during this exciting time in our history.
