The Greater Yellowstone Ecosystem harbors the last great populations of elk, pronghorn antelope, and mule deer. Photographer Joe Riis has spent over a decade here, revealing these animals' previously invisible migrations. Each year, these animals face natural challenges and man-made obstacles on their journeys--but Joe's images are galvanizing action in the Yellowstone ecosystem to preserve these fragile, ancient migration routes.
