Ok, here is the last photo of the bull elk (Cervus candensis) that I photographed just outside Mammoth Hot Springs.
Bull elk in sage brush with large rack of antlers during the fall rut (mating season). This bull elk has sparred with other bulls to establish his harem of females with which he hopes to mate.
