Yosemite National Park History - Increased Protection

Send in the Calvary

Theodore Roosevelt and John Muir on Glacier Point Overgrazing of meadows (especially by sheep), logging of Giant Sequoia, and other damage caused Muir to become an advocate for further protection. Muir convinced prominent guests of the importance of putting the area under federal protection. One such guest was Robert Underwood Johnson, editor of Century Magazine. Through Johnson, he was able to help pass an act of Congress that created Yosemite National Park on October 1, 1890. The State of California, however, retained control of the Valley and Grove. Muir also helped persuade local officials to virtually eliminate grazing from the Yosemite High Country.

The newly created national park came under the jurisdiction of the United States Army's Fourth Cavalry Regiment on May 19, 1891, which set up camp in Wawona. By the late 1890s, sheep grazing was no longer a problem, and the Army made many other improvements. The Cavalry could not intervene to help the worsening condition of the Valley or Grove.

Muir and his Sierra Club continued to lobby the government and influential people for the creation of a unified Yosemite National Park. Then in May 1903, President Theodore Roosevelt camped with John Muir near Glacier Point for three days. On that trip, Muir convinced Roosevelt to take control of the Valley and the Grove away from California and give it to the federal government. In 1906, Roosevelt signed a bill that did precisely that.
