Which site became the world’s first national park in 1872, a landmark in America250’s story?

Yellowstone National Park became the world’s first national park in 1872, making it a landmark in America250’s story. President Ulysses S. Grant signed the Yellowstone National Park Protection Act on March 1, 1872.

The park lies primarily in northwestern Wyoming, with smaller portions extending into Montana and Idaho. It is famous for geothermal features such as Old Faithful, the Grand Prismatic Spring, and the Yellowstone Caldera, one of the largest active volcanic systems in the world.

The national-park idea aimed to preserve Yellowstone’s scenery, wildlife, and geothermal wonders for public enjoyment rather than permit private development. The designation helped inspire protected-area systems in the United States and other countries.

Yellowstone is not the same as Yosemite, which became a national park in 1890. Yellowstone’s distinction concerns the first national park established anywhere in the world, not the largest or oldest protected landscape of every kind.
