Yellowstone is the national park located in the USA on the area of three states: Wyoming, Montana and Idaho. It is the first and oldest national park in the world. It is known mostly for geysers - sources, which rapidly throw hot water and steam. Geysers explode regularly and are able to throw water up to 70 cm. The Yellowstone Park delights with the beauty of geysers, which enchant with intensity of colors of the launched water. In 1978 the Yellowstone National Park was listed on the UNESCO World Heritage Site list.
