That's Old Faithful erupting at Yellowstone National Park. While many park visitors come with the expectation that it erupts hourly or on a truly regular schedule, the geyser actually is somewhat erratic and average 90 minutes between eruptions, although they can be between 45 and 120 minutes. The duration of each eruption is between 1.5 and 5 minutes and the geyser can erupt as high as 180 feet.

There are several other geysers in the park that are predicted besides Old Faithful, and we got to see some of them. For me, the most spectacular geyser isn't Old Faithful, but Steamboat geyser, which is the tallest geyser in the world, but hasn't had a major eruption in several years. While we were there, Steamboat put on a show of sustained 40 foot eruptions, but Steamboat is known for getting as high as 300 feet or more.
