Back in April of 2010, a local guy was killling a few hours before work like he always does...shooting film in the park. He parked his car on the side of this highway and heard a noise. He looked behind him to see this bison running for it's life from a grizzly. The guy got these shots and said that both ran right past him.
Pretty awesome picture.
The bison made it into the woods and lost the bear but he died exactly one day later. If you look in the first picture you can see that it looks pretty banged up. Park Rangers tracked the bison and found that it was injured. They said it had likely gotten caught in one of the parks hot spots and gotten badly burned. Later the next day, the rangers euthanized the bison. So sad but.....epic pictures.
