America’s first national park is 139 years old today!

Yellowstone became the first federally protected national park by an Act of Congress signed into law on March 1, 1872.

A Brief History Leading to Yellowstone’s Designation

In the years preceding the Civil War, U.S. government exploration brought a new awareness to the nation of the beauty and great natural resources of its vast western lands. Once the Union’s future was assured, the govenment’s attention turned once more to settling its western territory and exploiting it economic expansion.

The U.S. Army Corps of Engineers led the way, with Zebulon Pike, Stephen Long, John C. Fremont, George M. Wheeler and others charting the landscape. The Smithsonian Institution and the Department of the Interior worked toward similar ends, until all civilian and military mapping was consolidated under the U.S. Geological Survey.

Civilian explorers followed in the footsteps of military engineers, as individuals like Clarence King, John Wesley Powell and Ferdinand Hayden conducted field studies on the geology, flora and fauna of the West. They published their results in scientific journals and popular magazines, gave interviews to newspapers and provided the first images of the West’s dramatic natural features to the population base on the East Coast via the early photographic techniques. Adventurous artists followed suit, capturing the drama and monumental scale of western landscapes in what were to become iconic paintings.

As public interest in the West grew, American attitudes toward it shifted.  It was no longer seen primarily as a daunting wilderness to be survived en route to the Pacific, but as a trove of natural treasures awaiting discovery by the populace, who were enticed to see the West’s scenic splendors for themselves. Nature was regarded as a balm for the weary urban soul, and a western vacation a conduit for inner transformation. And with such changing perceptions came a push to preserve the country’s greatest natural features from the exploitation that was rapidly changing the face of the West by the second half of the 19th century.

The Birth of the National Park System

The creation of the national park system was at the forefront of such efforts. Following the state of California’s designation of Yosemite as parkland in 1864, the federal government focused its gaze on an equally wondrous tract of land in what would become the northwest corner of Wyoming.

Early trappers and army explorers had been profoundly impressed by the upper reaches of the Yellowstone River, which Ferdinand Hayden had surveyed in 1871. Upon his return to the East, he mounted a campaign to promote, but also to protect, the natural wonders he had seen. He quickly wrote a well-received article for Scribner’s Monthly that included fellow expedition member Thomas Moran’s illustrations. He provided Charles Bierstadt, brother to the artist and a leading manufacturer of stereographic cards, with copies of William Jackson’s expedition photographs. He lobbied members of Congress by presenting them with an album of Jackson’s Yellowstone photographs. He was supported in his effort by Jay Cooke, the railroad magnate who anticipated increased tourist ridership on his lines serving the Yellowstone area. His campaign resulted in a decision by Congress on March 1, 1872, to pass into law the act creating Yellowstone as “a public park or pleasuring-ground for the benefit and enjoyment of the people.”

See Yellowstone for Yourself!

Natural Habitat Adventures offers winter and summer tours to Yellowstone. Winter is a magic time, when wolves are most easily observed in the frozen reaches of the pristine Lamar Valley. Beneath the snow and ice, the earth thrums with energy, as the spray of steaming geysers freezes in mid-air. In summer, our trips take you well away from the crowds and into the backcountry where our naturalist guides have an inside track on the best wildlife viewing opportunities.

Here’s to our national parks, one of America’s best ideas!

Yours as we celebrate,


P.S. If  you’d like to read the original text of the law that established Yellowstone as our first national park, here it is:

Transcript of Act Establishing Yellowstone National Park (1872)

Forty-Second Congress of the United States of America;
