Shoshone National Forest is the first federally protected National Forest in the United States and covers nearly 2,500,000 acres in the state of Wyoming. Originally a part of the Yellowstone Timberland Reserve, the forest is managed by the United States Forest Service and was created by an act of Congress and signed into law by U.S. President Benjamin Harrison in 1891. Shoshone National Forest is one of the first nationally protected land areas anywhere. Native Americans have lived in the region for at least 10,000 years, and when the region was first explored by European adventurers, forestlands were occupied by several different tribes. Never heavily settled or exploited, the forest has retained most of its wildness. Shoshone National Forest is a part of the Greater Yellowstone Ecosystem, a nearly unbroken expanse of federally protected lands encompassing an estimated 20,000,000 acres.
The Absaroka and Beartooth Mountains are partly in the northern section of the forest. The Wind River Range is in the southern portion and contains Gannett Peak, the tallest mountain in Wyoming.
