Which forest became the first national forest created by the United States government in 1891?

Shoshone National Forest became the first national forest created by the United States government in 1891.

President Benjamin Harrison proclaimed the Yellowstone Park Timber Land Reserve on March 30, 1891. It was later renamed Shoshone National Forest, making it the oldest national forest in the United States. The forest lies in northwestern Wyoming and covers portions of the Absaroka, Beartooth, and Wind River mountain ranges.

Its landscape includes alpine peaks, glaciers, forests, sagebrush, and river valleys. The forest is adjacent to Yellowstone National Park and includes parts of the Greater Yellowstone Ecosystem, a large region supporting grizzly bears, wolves, elk, bighorn sheep, and other wildlife.

The 1891 law gave the federal government authority to reserve forest lands, establishing the legal foundation for the national forest system. Shoshone is therefore different from Yellowstone National Park, which was created in 1872 as a protected park rather than a national forest.
