Near Kelly, Wyoming —- Who knew that bison have black tongues? In this image, I caught Mama Bison chewing some plants while looking in my direction. I was shooting with a 600mm lens from a safe distance. At least, we hoped we would be safe!

In this next close-up, you can see the bison trudging up the hill in fresh snow. It was also snowing, windy and cold. I like the raised hoof indicating the action taking place. In no time, all five bison had traveled from the field where they were lying, through the hot spring, across the road and up the hill.

This was our best sighting of the week in Jackson Hole. While we spotted moose several times, we never had a good opportunity for photos like this. A shout out to our guide with Wild Things of Wyoming, Colin Boeh, for his experience with finding and safely observing wildlife in Grand Teton National Park. Thanks to Colin, we had a fascinating and very educational day!
