  • We were watching old faithful and this geyser started erupting and it was beautiful. We started walking towards it and it was going on strong for a while after we reached there. You can go much closer to it than old faithful.
  • Fast facts: Elevation: 7,333 feet Eruption height: 90 feet (27 m) Frequency: 10 to 12 hours Duration: 20 minutes Castle Geyser is a cone geyser in the Upper Geyser Basin of Yellowstone National Park. It is noted for the particularly large geyserite sinter deposits, which form its cone. These deposits have been likened in appearance to a castle. When the geyser was given this name in 1870, the top edges of the structure resembled the typical profile associated with the modern concept of a castle, having the appearance of a large keep, multiple turrets, and especially because of the crenelation along the top edges of what resembled its towers. As the drawing below shows the cone had distinctive appearance at the time. Over time the cone's shape changes because of the layers of mineral deposited in successive eruptions.
