American Elk - Rocky Mountain National Park, Colorado
Every autumn the annual rut, or breeding season, of the American elk takes place. The mountains and valleys of Rocky Mountain National Park reverberate with the sounds of bugling bull elk as the gather their harems in a timeless ritual that began eons ago.
This is the third release in my "Mammals of North America in Black & White" series. It was made a few week ago, while guiding a friend in Rocky Mountain National Park.
