The world’s tallest geyser erupted on Wednesday night for the first time in over eight years. Yellowstone National Park spokesman Dan Hottle reports that Steamboat Geyser spewed water close to 300 feet in the air for eight to nine minutes in front of 30-40 lucky spectators.
According to Hottle there is a water temperature logger kept in Steamboat’s runoff to monitor for temperature increases, but they mostly rely on the public to report activity.
This was Steamboat’s first major eruption since May 23rd, 2005. The geyser had previously gone as long as fifty years without a major eruption. It’s most active year was 1964, when it erupted 29 times.
