Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. Yellowstone's awe-inspiring sights like must-see Old Faithful and the rainbow-colored Grand Prismatic Springs are showstoppers, but the park is also home to 10,000 geothermal features, including 500 active geysers, hot springs, mud pots and fumaroles. #yellowstone #yellowstonenationalpark #oldfaithful #Wyoming #usa #national
