Wednesday, Sept 3, 2014: Steamboat Geyser in Yellowstone's Norris Back Basin erupted unexpectedly Wednesday evening. Rosa Prasser, a Yellowstone Ranger, witnessed the eruption at 11:00 pm.
The last time Steamboat had a major eruption was in July, 2013. In the past, Steamboat has gone 50 years without a major eruption, and in 1964, it erupted a record 29 times.
Steamboat Geyser is the world's tallest geyser and can shoot hot water up to 380 feet in the air. This phase of the eruption can last from a few minutes, up to 40 minutes. Wednesday, it lasted for several minutes. After the eruption, the geyser will shoot steam for 1-2 days.
