What a marvelous week I just spent in Montana and Yellowstone National Park. Winter storms blanketed the area with snow and the temperatures dropped to the single digits and even below zero. One day, we were fortunate to watch as a band of Rocky Mountain Bighorn Sheep made their way down a slope, across the road, and down to the Yellowstone River to drink. They quickly acclimated to our presence and we were able to approach them without scaring them away. This ram posed for quite a while on the edge of the road. Nikon D5, Nikkor 500mm PF.
