The Grand Canyon of the Yellowstone at Lookout Point.

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
