Steamboat Geyser, in Yellowstone National Park's Norris Geyser Basin, is the world's tallest currently-active geyser. During major eruptions, water may be thrown more than 300 feet (91 m) into the air.
Steamboat's major eruptions last from 3 to 40 minutes, and are followed by powerful jets of steam. Steamboat does not erupt on a predictable schedule, with recorded intervals between major eruptions ranging from four days to fifty years. The geyser was dormant from 1911 to 1961. Minor eruptions of 10 to 15 feet (3.0 to 4.6 m) are much more frequent. After an eruption, the geyser often vents large amounts of steam for up to 48 hours. Cistern Spring, located nearby, will drain completely during a major eruption of the geyser; the spring refills within a few days.
Prior to 1904, Waimangu Geyser, in New Zealand, had some taller eruptions capable of reaching 1,600 feet (490 m), but in 1904, a landslide changed the local water table, and since then, Waimangu has not erupted. Excelsior Geyser in Yellowstone's Midway Geyser Basin likewise was taller, with eruptions reaching 300 feet (91 m). However, Excelsior has not erupted since 1985, and now functions as a hot spring (though eruptions are, as in all hot springs, still a possibility).
The most recent eruption of Steamboat Geyser occurred on July 6th, 2018 at 1:38 PM. While years may pass between eruptions some years see multiple eruptions including 29 in 1964. Eruptions from 1990 to current years include:
- June 4, 1990
- October 2, 1991 - (1 year 120 days)
- May 2, 2000 - (8 years 213 days)
- April 26, 2002 - (1 year 359 days)
- September 13, 2002 - (140 days)
- March 26, 2003 - (194 days)
- April 27, 2003 - (32 days)
- October 22, 2003 - (178 days)
- May 23, 2005 - (1 year 213 days)
- July 31, 2013 - (8 years 212 days)
- September 3, 2014 - (1 year 34 days)
In 2018, Steamboat Geyser entered a much more active period with eleven eruptions recorded between March 15th and July 6th.
- March 15, 2018 - (3 years 193 days)
- April 19, 2018 - (35 days)
- April 27, 2018 - (8 days)
- May 4, 2018 - (7 days)
- May 13, 2018 - (9 days)
- May 19, 2018 - (6 days)
- May 27, 2018 - (8 days)
- June 4, 2018 - (8 days)
- June 11, 2018 - (7 days)
- June 15, 2018 - (4 days)
- July 6, 2018 - (21 days). This is the first eruption since the May-June 2018 disturbance of the Norris Geyser Basin.
Steamboat Geyser has two vents, a northern and a southern, approximately five meters apart.
