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.
Trail to Observation Point Old Faithful Area, Yellowstone National Park, Wyoming
Overall, the trail was in good shape. A slight detour was needed to keep away from a lone bison though. - February 03, 2011 - 1/400 sec at f / 10 - 19 mm - ISO 200 - 44°27'44" N 110°49'38" W
