September in Yellowstone means autumn and autumn means colors! Yellowstone has very few deciduous trees. Aspens are about the only tree that shows any color in Yellowstone and there aren’t big stands of them as there are in other places. But the golden grasses certainly help to make photography magical. It’s still hot here in what has been a very hot year that has seen record heat and drought. As such, the only elk I’ve seen recently disappear into the trees before the sun comes up as they hide from the heat. The bison have moved from Hayden Valley to Fountain Flats as they disperse from the breeding season. This bull bison was by himself as he passed in front of a beautifully backlit thermal feature. The scene was amazing as the sun did it’s magic on the landscape.
