If you’ve ever driven across the wide-open sagebrush seas of Wyoming, you’ve likely seen a flash of tan and white blurring past the horizon. That "ghost of the prairie" is the Pronghorn (Antilocapra americana), and it isn't just another herbivore. It is the fastest land mammal in North America, built for explosive speed and elite endurance in open country.
At Moss Apparel, we are obsessed with the stories behind the wildlife we photograph. The Pronghorn isn't just an icon of the American West; it's a testament to endurance and the critical need for open spaces. When you wear our wildlife t-shirts, you’re carrying that story with you.
EVOLVED FOR SPEED
The Pronghorn is the fastest land mammal in the Western Hemisphere. It can hit top speeds of around 60 mph and, even more impressively, hold 35-40 mph for miles. That combination of burst speed and stamina is what makes it so remarkable.
But here’s the kicker: speed is only part of the story. The Pronghorn is packed with biological adaptations that make that performance possible. It has an oversized heart, powerful lungs, an enlarged windpipe, and a highly efficient respiratory system built to move huge volumes of oxygen. Its lightweight frame, long legs, and specialized muscles help it cover ground fast without burning out right away.
Evolutionary biologists believe the Pronghorn developed this extreme athleticism to outrun predators that no longer exist, including the American Cheetah. While those Ice Age pursuers disappeared more than 10,000 years ago, the Pronghorn kept the engine. Today, it remains one of the best examples of how anatomy, habitat, and evolution can all work together in one animal.

THE WYOMING ODYSSEY: 150 MILES OF PERIL
Speed is one thing, but endurance is another. Every year, Pronghorn in western Wyoming undertake one of the longest big-game migrations in the lower 48 states. Known as the "Path of the Pronghorn," this 150-mile trek takes them from the summer ranges of Grand Teton National Park down to the wintering grounds of the Upper Green River Valley.
This isn't a casual stroll. These animals are following ancestral routes etched into their DNA. However, the modern world has placed some serious hurdles in their way. Unlike deer or elk, Pronghorn aren't natural jumpers. They prefer to go under obstacles rather than over them.
THE BARRIER PROBLEM: FENCES AND HIGHWAYS
In the wide-open West, "under" is a dangerous proposition when it comes to traditional barbed-wire fencing. A standard fence often has a bottom wire that is too low, catching the backs of Pronghorn and causing fatal injuries or simply blocking their path entirely. If a herd can't reach its winter range because of a new fence or a busy highway, they won't survive the brutal Wyoming winter.
Highways are equally treacherous. Annually, there are roughly 6,000 vehicle collisions with big game in Wyoming. For a species that relies on a specific 200-yard-wide "bottleneck" passage to complete its migration, a single highway expansion or a new subdivision can be catastrophic.
THE WYLDLIFE FUND: CONSERVING THE CORRIDOR
This is where our partners at The WYldlife Fund come in. They are doing the heavy lifting on the ground to ensure these migration corridors stay open.
As of late 2024, The WYldlife Fund has awarded over $3.3 million to more than 80 projects across the state. Their work is direct, utilitarian, and highly effective. Some of their key initiatives include:
- WILDLIFE-FRIENDLY FENCING: Replacing miles of outdated barbed wire with designs that have a smooth, higher bottom wire, allowing Pronghorn to "zip" under at full speed without a scratch. They recently funded 23 miles of this in the Red Desert.
- HIGHWAY CROSSINGS: Supporting massive infrastructure projects like the Dubois US 26 and Kemmerer HWY 189 crossings. These overpasses and underpasses allow wildlife to cross busy roads without the risk of a collision.
- THE PRONGHORN FUND: A dedicated initiative specifically aimed at safeguarding Wyoming’s "crown jewel" through habitat research and corridor protection.

HOW YOU CAN HELP
Conserving the fastest land animal in North America requires more than just admiration; it requires action.
- SUPPORT THE WYLDLIFE FUND: Your donations go toward putting "money on the ground" for fencing projects and highway crossings.
- DRIVE WITH CARE: If you’re traveling through Wyoming, especially at dawn or dusk, slow down and watch for the white rumps of Pronghorn near the road.
- CHOOSE SUSTAINABLE APPAREL: Support brands that prioritize ethical supply chains and direct conservation funding.
The Pronghorn has been running across these plains for millions of years. By protecting their migration corridors today, we ensure they’ll be blurring across the Wyoming horizon for millions more.
