Bombardier Transportation Snow Lodge, Upper Geyser Basin, Yellowstone National Park, Wyoming

These were used for the trip between the Upper Geyser Basin and the Canyon area where there is always snow. It was almost time to get in for the ride up to Norris, down to the canyon, by Fishing Bridge, and finally West Thumb to complete the loop. The guide said new emission standards were going to force these out of service in a few years unless they do some major modifications. The guides driving these have a secondary job of flattening out any ridges in the snow caused by other tracked vehicles. - February 05, 2011 - 1/160 sec at f / 6.3 - 24 mm - ISO 200 - 44°27'23" N 110°49'46" W
