Yellowstone National Park’s Giantess Geyser has burst into life again after 2 years, 139 days and 12 minutes of silence. This was big news for geyser gazers and fans of Yellowstone. Normally, Giantess erupts once or twice each year, so the latest 2.4-year pause was one for the record books. Giantess is a favorite geyser among enthusiasts. Its eruptions can be heard a mile away and can last more than a day.
