Library of Congress Blog This post is based on an article from the November–December 2016 issue of LCM, the Library of Congress Magazine. Carleton Watkins captured this view of Yosemite’s Mirror Lake while most of the country was engaged in the Civil War. National parks are among the nation’s most cherished natural resources. The National Park Service, a bureau of the U.S. Department of Interior, was created by an act of Congress. On August 25, 1916—101 years ago today—President Woodrow Wilson signed the act into law. A century after its founding, the National Park Service overseas more than 400 sites, in every U.S. state and territory. One of these sites is California’s Yosemite National Park. Subsequent efforts by landscape designer Frederick Law Olmsted and naturalist John Muir resulted in Yosemite becoming a national park in 1890—decades before the establishment of the National Park Service.
