Hi Bob. Welcome to the zoo. I have been to the geysers a couple of times and it is something to see. Olga Kobreck who owns the geysers use to keep a record of the eruptions particularly when the frequency of the eruptions changed. It’s my understanding she no longer does that, but there is a person from USGS who is keeping a record. I can’t think of his name at the moment, but Petra knows who he is. I’m sure will post what she knows.

I thought that maybe you and your students would enjoy reading the "Legend Of The Geysers." Take Care…Don in creepy town
