For at least the last 6,000 years, pronghorn antelope have trekked more than a hundred miles between Grand Teton National Park and the sagebrush basins of the Upper Green River of Wyoming. Their age-old route is becoming increasingly fragmented by roads, fences, oil rigs, and all manner of human development.
Adventurer Rick Ridgeway and photographer Joe Riis set out to discover the migratory bottlenecks that pronghorn face — by painstakingly walking out their ancient route. Here’s what they found:
“I photograph this migration to inspire people to care about it. It is an incredible migration and people need to know about it — It is happening right in the middle of the U.S. and it is the second longest migration in the western hemisphere.” — Joe Riis, photographer
Over the years, the Land Library has never been able to pass by a book on pronghorn. Here’s three of our favorites!
Built for Speed: A Year in the Life of Pronghorn by John A. Byers, Pronghorn: Portrait of the American Antelope by Gary Turbak, Prairie Ghost: Pronghorn and Human Interaction in Early America by Richard E. McCabe, et.al.
