Bison in the Mirror (Portrait with border)
These animals were nearly hunted to extinction. Westward expansion of European settlers in the 1800's put too much strain on the bison population, which had been respected and conserved by native American tribes for centuries. It was only through education and efforts by the government that the animal was saved.
Today, there are numerous herds of bison in the western United States. The protection afforded by the boundary of the national park has also given the herds a place to thrive and repopulate.
Bison are very dangerous, although they tend to move slowly when not disturbed. Never approach bison, under any circumstances. The number two cause of fatalities in Yellowstone is bison attack. Can you guess the number one cause of fatalities in Yellowstone?
It is not bear attacks. In fact, bear attacks are relatively rare. The number one cause of fatalities within the Yellowstone boundary area is hot water burns from people falling into Yellowstone's thousands of hot springs.
