Steamboat Geyser is the largest geyser in Yellowstone. When it spews it can be as high as 300 feet. I have not had the opportunity to see if go off yet. Steamboat runs on its own schedule. Last year it went off about 30 times. This year it looks to be on track for a repeat performance. The geyser has gone off numerous times but we have yet to catch it. It has gone off on June 1st, 7th, 12th, 15th, 19th, 23rd, and 28th.
This geyser is interesting to watch even when a large eruption is not happening. There is always steam rising and water spurting about. I have seen water shoot about 40 feet in the air. I can only imagine what a full eruption looks like.
I spent an evening taking picture after picture of this geyser. We have been to the Norris Geyser Basin twice; May 6 and June 7. All these pictures were taken within 3 minutes on the evening of June 7.

I seem to have Steamboat Geyser repellent. I kept traveling over to this geyser basin but seem to miss the eruptions to either being 10 hours to late and 12 hours to early. I live and work approximately 40 miles from this basin. It is not a quick trip. I did see it after the major eruption that happened the evening of July 4th. This was the first time I saw this geyser quiet. There was no sound at all. There was steam and no sound. That was a first for Donna and I. Here are some pictures from that day.
