  • Predicting Old Faithful
  • Many eruptions of Castle start with little or no warning. A major eruption usually occurs every 9-11 hours. The water shoots between 60-90 feet (18-27 m) and blasts for about 20 minutes. A noisy steam phase follows which lasts another 30-40 minutes.

    Castle Geyser Erupts

    Occasionally Castle Geyser has minor eruptions that have a short water phase (up to 11 minutes), but no steam phase. A minor eruption may be followed by violent splashing which can last for hours but never build into a full eruption. When Castle has a minor eruption, the geyser becomes unpredictable until its next major eruption.
