Updated on Oct. 6, 2026 in National Parks
Hundreds of bison stampeded through a fence line in Grand Teton National Park. The animals broke through wire fencing as they moved across the prairie.
Why it matters
Bison stampedes highlight the potential for significant damage to park infrastructure and the unpredictable nature of wildlife in protected areas.
A single bison can weigh as much as 2,000 pounds and reach top speeds of 35 mph. The stampede involved hundreds of these animals plowing over a wire fence line to reach a new prairie section.
The details
The animals swept across the prairie in Wyoming before crowding and forcing their way through the barrier. The footage captures the immense power of the herd as they navigate the landscape, effectively flattening the fence line in their path.

Travel Outlook
This event follows a pattern of wildlife activity observed in recent years within Wyoming park systems. These movements reflect seasonal shifts that periodically force large herds to navigate established park boundaries.
Visitors to Grand Teton should maintain significant distance from wildlife, as bison can reach speeds of 35 mph. Travelers should always follow park ranger guidance regarding trail and road closures following infrastructure damage from herd movements.
The takeaway
Wildlife encounters require heightened awareness because even stationary barriers cannot contain the movement of a massive bison herd. Always prioritize your personal safety by observing herds from a safe distance in your vehicle.
