Yellowstone is the only place in the United States where Bison – commonly called American Buffalo – have lived continuously since prehistoric times.
They once covered the Great Plains of North America in numbers estimated as high as 60 million, but were nearly driven to extinction by slaughter in the 19th Century. There are now close to 5,000 Bison living in Yellowstone National Park, one of the best reasons to visit.
The largest land-dwelling animal in North America, males weigh up to 2,000 pounds, females up to 1,100 pounds. Visitors must be alert at all times and keep a safe distance away as posted signs warn. Unfortunately many people are injured by the animals each year by approaching too closely. All of my pictures were taken safely from a distance, sometimes from inside my vehicle where I always gave them the right-of-way.
