Elk, pronghorn, and mule deer migrations are a wonder of the Yellowstone National Park ecosystem, and one that few people have ever seen. Each year, fleet-footed pronghorn, towering elk, and floppy-eared mule deer travel hundreds of miles through streams, forests, and mountains, embarking on long and sometimes perilous journeys to new feeding or mating grounds.

In National Geographic's “Stunning Footage: Epic Animal Migrations in Yellowstone,” nature photographer Joe Riis has captured stunning footage of some of these migrations. In the video above, watch as herds of animals travel through the gorgeous landscapes of Yellowstone National Park, and learn about their fascinating migratory patterns.
