The longest land migration in the lower 48 happens in Wyoming. Each spring, 200-300 pronghorn antelope trek 170 miles from southwestern Wyoming to Grand Teton National Park. Part of the path is through booming southwestern Wyoming. It's filling in with homes, and oil and gas wells. Some fear it might be pinched off, ending the migration forever. This has prompted calls for Congress to create the first National Migration Corridor, a kind of 90 mile by 1 mile national park. Meanwhile, federal land managers are protecting the corridor piece by piece. In this story, I follow part of the pronghorn's route on foot, alongside a woman who is living with the antelope for the next year. Listen for campfire-side interviews, hikes through sagebrush, and a scene at a bottleneck where pronghorn crawl on their knees under a fence, as dogs bark and four-wheelers rumble.
