Another eruption we witnessed was that of Daisy Geyser which was also fairly predictable but not nearly as frequent as Old Faithful. An unusual thing about Daisy is that the outflow of water is not vertical. We spent quite a bit of time waiting out the appearance of the eruption but it was worth it. The second part of this video shows "liquid gold" running off from the geyser pool after the eruption.
It was difficult to resist the temptation to photograph the tourists, so here are a few more.
