Steamboat Geyser, the tallest active geyser in the world, delighted visitors to Yellowstone National Park on Wednesday, spewing steam high into the air in a rare and powerful eruption that lasted several minutes and resulted in ongoing steam and rumbling that persisted until Thursday morning.
Full eruptions of Steamboat are rare and unpredictable, and are prized by geyser gazers who wait to witness a rare column of super-heated water that can reach more than 300 feet. Eruptions can last only a few minutes, or as long as 40 minutes, with this week’s outburst lasting a reported 15-20 minutes.
