A male, or bull, elk, of the North American species of elk, Rocky Mountain subspecies, walks through the yellow and burned out grasses in the fog and mist on an autumn day in the early morning just after sunrise, as the fog begins to lift, in Rocky Mountain National Park, Colorado. This subspecies of elk is said to have the largest antlers of all North American elks.
