As we move into the bison mating season (the rut) groups of bison will be at their largest. Give wildlife the right of way when they cross the road, stay inside your vehicle, and use pull-outs when you stop for photos. #YellowstonePledge | Yellowstone National Park

The water was two feet higher the last time I was on this gravel bar, and it's likely that I waded within a foot of this skull then. It's so much easier when you can see them. | Bison Bison Paleo Fossils | Facebook

Typically, there's nothing buried beneath a foramen magnum that you find on a gravel bar, it's normally just broken off and lying partially buried by itself. But luckily, this time there was something beneath it. | Bison Bison Paleo Fossils | Facebook

WATCH THESE BISON SWIM THE YELLOWSTONE RIVER 👀 This small herd of bison decided to take a nice cold swim this spring (notice the melting snow ❄️ on the riverbank) in the Yellowstone River! Bison are the largest mammal in North America. Male bison (called bulls) weigh up to 2,000 pounds and stand 6 feet tall, while females (called cows) weigh up to 1,000 pounds and reach a height of 4-5 feet. It's hard to believe these large creatures can swim but as you can see from the video they do just fine!
