One of a pair of Coyotes trotted down the hillside in the Lamar Valley last week in Yellowstone National Park, seemingly on a mission. While we photographed them from the side of the road, the heat shimmer rising up between us and the Coyotes was a bit of a problem at times, sometimes preventing sharp images. The traffic wasn’t bad and after they came down the hillside, they crossed the road and disappeared from view.
