Grand Teton National Park and a 6,000 year Old Migratory Path

Path of Pronghorn Spring Migration Pinedale WY

Each spring and fall, hundreds of pronghorn migrate 170 miles to and from their important summer range in Grand Teton National Park. For over 6,800 years, members of this indigenous Teton herd travel back to the Pinedale region, a place rich in water and hardy forage that fosters the largest gathering of pronghorn on earth. The herd's biannual journey includes crossing four major rivers, the New Fork, the Green, the Gros Ventre, and the Snake, through a 9,000 foot pass in the Gros Ventre Mountains, and two wildlife overpasses on US Highway 191.

This great Pronghorn migration, named by U.S. biologists as the "Path of the Pronghorn", is remarkable and one of the last long-distance land animal migrations in the world. For a patient visitor, bring a spotting scope and a warm coat and be prepared to see wildlife appear on route from US Highway 191/Wyoming Centennial Scenic Byway. Located six miles north of Pinedale, experience the nation's first federally designated protected migration corridor that not only protects this exclusively American animal, but several other species of Wyoming wildlife.
