Pronghorn Antelope and the High Cold Desert
As you travel this highway, small groups of the herd can be viewed during the late spring and summer. As the fall season turns into winter and snow begins to cover their food sources, thousands of pronghorn begin migrating south to open areas to feed. One of the longest big game migrations in North America, some segments of the herd migrate up to two hundred miles. From as far north as Grand Teton National Park, south to Rock Springs, much of the migration parallels this highway - a route favored both by pronghorn and humans.
The Sublette herd survive the harsh conditions of the "high cold desert" by travelling long distances, therefore an open migration route is crucial to their survival.
