Yellowstone National Park, US

The world’s largest geyser has exploded to life at Yellowstone National Park for the first time in eight years, sending a high-pressure burst of steamy water 300 feet into the air, a park official said on Thursday. The stream of 160 degree water released on Wednesday night by the so-called Steamboat Geyser lasted for roughly 10 minutes, delighting a small number of “geyser gazers” who have waited years for such a show, Yellowstone spokesman Dan Hottle said.
