World's Tallest Active Geyser Erupts in Yellowstone National Park for the 3rd Time

Although infrequent, the eruption of Steamboat Geyser in Yellowstone National Park's Norris Geyser Basin can send hot water an estimated 200 to 300 feet in the air.

World's Tallest Active Geyser Erupts in Yellowstone National Park for the 3rd Time in 6 Weeks

Yellowstone National Park geologists have reported the third eruption from the world's largest active geyser in the past six weeks.

The National Park Service says a park visitor reported seeing a rare eruption of Steamboat Geyser on Friday.

Park geologists compared the report with seismic activity and the discharge of water and concluded the eruption probably started at 6:30 a.m.

The geyser also erupted on March 15 and April 19.

All three eruptions were smaller than the last major eruption that occurred on Sept. 3, 2014.
