Location: Yellowstone National Park. Wyoming. US

The American bison, also known as buffalo, once roamed the grasslands of North America in massive herds. They became nearly extinct, but have made a recent resurgence largely restricted to a few national parks and reserves. If you are visiting Yellowstone National Park, you will come across few of them for sure.

The bison's temperament is often unpredictable. They usually appear peaceful, unconcerned, even lazy, yet they may attack anything, often without warning or apparent reason. Their most obvious weapons are the horns, but their massive heads can be used as battering rams, effectively using the momentum produced by 2,000 pounds (900 kg) moving at 30 mph (50 km/h).

There are over 4,000 bison residing in Yellowstone and are the main cause of summer jams in the park. Traffic can be at a standstill for hours but still we love them. Given their apparently docile nature Yellowstone visitors loose precaution when approaching and that's when they become victims. Bison can exceed speeds of 30 mph (50 km/h). How fast can the average Yellowstone tourist run? The smart money would be on the bison...
