Quiet rut in Yellowstone

Wild elk walk through the Mammoth area of Yellowstone National Park as tourists look on in this photo from August. There have been far fewer reports of elk damaging tourists' cars during the fall elk mating season following last winter's death of elk No. 6, a large and well-known bull that had a penchant for attacking vehicles.
