Started out in Bozeman, stayed a first night in Mammoth Hot Springs, stayed several days around Old Faithful, and then back to the Mammoth Hot Springs area for the Wolf Discovery tour.
The drive from Bozeman to the Mammoth area of Yellowstone was pretty nice. - February 01, 2011 - 1/500 sec at f / 11 - 24 mm - ISO 200 - 45°5'9" N 110°46'33" W
