Yellowstone is America’s first National Park, covering approximately 3,500 square miles of lakes, canyons, rivers and mountain ranges. It’s also home to the world’s largest active super volcano and half of the world’s geothermal features. The most famous one of course is Old Faithful. Named in 1870, it sits majestically in northern Yellowstone, faithfully shooting its geyser 185 feet into the air, on average every 91 minutes. The Washburn Expedition explorers and scientists were amazed by Old Faithful’s height and regularity. Soak in the beauty and complexity of this national park, full of cascading waterfalls, geysers, and all types of wildlife your and tourists alike love!
