This is a high plains desert, there will be no shade trees after you leave the city streets. Many runners stop and take photos of the vistas and any wild horses  and other wildlife they encounter. This is an up and back course, at the halfway point of each respective race you will turn around and return back to Green River to the Expedition Island.

PILOT BUTTE Run Wild and Let Your Mane Fly

  • Be a witness to the untamed West with a visit to Pilot Butte, where a herd of wild horses can be viewed and photographed. As you hear the thunderous sound of pounding hooves in the wide-open landscape, you will realize that the frontier spirit is still alive and well. 
  • With a population of about 1,500 head, chances are strong that you will be able to admire these wild horses during your visit. As descendants of the horses who were reintroduced to the area in the 1800s by cattle ranchers, you are witnessing the living story of the West.
  • The Pilot Butte Wild Horse Scenic Loop offers the best chance to see the wild horses. This 24-mile, self-guided tour takes about 90 minutes, traveling between Rock Springs and Fourteen-Mile Hill, and all the way across the top of White Mountain. Stay on the lookout for other critters like pronghorn antelope, desert elk, deer, rabbits, coyotes, hawks, eagles and sage grouse.
  • To help guide you on your trip, here is a brochure with a map and information on the Wild Horses of Sweetwater County.
  • If you’re short on time, visit the Rock Springs Wild Horse Holding Facility, where wild horses are sheltered short term before adoption. At your own pace, you can view these magnificent animals year-round from a viewing kiosk that overlooks the facility. In the spring, you can see the adorable foals at play.
