- Pronghorn, Interrupted Photo
- Each autumn, the pronghorn of Wyoming’s Grand Tetons take off for their wintering grounds in the Upper Green River Basin. Despite being North America’s fastest land animal, these mammals face plenty of obstacles—fences, roads, and oil and gas development—that slow their 150-mile journey. In 2008, the U.S. Forest Service created the “Path of the Pronghorn,” our country’s first federally protected wildlife migration corridor. As the pronghorn migrate, WCS scientists monitor their journeys, collecting information that will help ensure safer travels for generations to come.
