This photo was taken last week on one my my explorations into Yellowstone. Nothing screams Yellowstone to me more than an image that shows both bison and thermal features. Yellowstone is home to the largest free roaming herd of bison in the world and is also home to the largest concentrations of thermal features any on the planet. While certainly not one of my best bison or thermal feature photos if you notice carefully, the cow bison has a nasty scar on her face. In the shape of an “L” it fortunately has healed nicely and she seemed to be in good health. Whether it was caused by the horn of another bison during a conflict, or perhaps an encounter with a predator, there’s not way to tell, but she is healthy and also very pregnant and will soon bring another bison calf into the world. Speaking of which, while I saw my first bison calf last week, and in a very pretty situation for a photo, there was no where to legally stop along the road, so it will remain a pleasant, unphotographed memory.
