While taking a look at some of the recent data posted to the GOSA website, I discovered a rather significant error in the write-up about Castle; to wit: "Castle is a cone-type geyser. Its interval is 9-11 hours and its height is 60-90 feet. The twenty minute water phase of a major eruption is followed by a 40 minute steam phase. The first 15 minutes of the steam phase is relatively forceful and fairly loud so try to be close for this part. As in most geysers that have a steam phase, the change from water to steam is gradual and an exact time for the change can rarely be noted." I think the interval has changed somewhat....
