In September of 2011 we spent a week in Yellowstone National Park. Established in 1872, Yellowstone National Park is America's first national park. Located in Wyoming, Montana and Idaho, it is home to a large variety of wildlife including grizzly bears, wolves, bison, and elk. Preserved within Yellowstone National Park are Old Faithful and a collection of the world's most extraordinary geysers and hot springs, and the Grand Canyon of the Yellowstone. It is also the most thermally active place on earth. My pictures don't do it justice.
