We were a little disappointed in bison sightings. There are around 2000 at the TGP Preserve we read but only saw a few and they were specks in the distance. we drove through, ate in Pawhuska and went back through right at dusk. Saw a ton of whitetail but no more bison.
I don't know why my luck with Google Image search is so bad, but when I look for images similar to that one, I get everything from alligators to goats. No snakes. I can only conclude that what you have there is not a snake.
