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.
Snow on Boardwalk Old Faithful Area, Yellowstone National Park, Wyoming
The boardwalks often have snow where the surround ground has none. This is between the parking lot and the main Old Faithful viewing area. No problem being off the boardwalk here. - February 02, 2011 - 1/800 sec at f / 14 - 24 mm - ISO 200 - 44°27'34" N 110°49'42" W
