After 4 hours of driving from Twin Falls, we arrived in West Yellowstone, Montana. This is a small and touristy town, right next to the Yellowstone National Park entrance.
Yellowstone National Park is the oldest national park in the world. With 8987 km² area it is one of the largest national parks in the United States. 96 percent of the park are located in Wyoming, 3 percent in Montana and 1 percent in Idaho. Yellowstone is best known for its geothermal springs such as geysers and mud pots, as well as its wildlife such as bisons, bears and wolves. In 1978, UNESCO declared it a World Heritage Site.
We were greeted by a Bison (Bison bison) and a fantastic scenery. An Osprey (Pandion haliaetus) had chosen the top of a tree as a lookout point.
Together with many other people, we watched the most famous geyser Old Faithful errupt and walked along a boardwalk trail in the Upper Geyser Basin.
Although night temperatures were already down to 0°C (32°F) and the trail was pretty crowded, we saw a Wandering Garter Snake (Thamnophis elegans vagrans) close to Firehole River. The bluish eyes indicate the forthcoming shedding of the skin.
