I am not sure what the current intervals are, but I do remember that back in the early 2000s, they were close enough to 3 hours that if someone had written it in the logbook the day before it was easy to determine a good estimate for the current day. Especially handy if someone had reported the times to the VC - great way to plan a hike/bike.

The logbook was still there when I visited in July. It's an interesting cultural artifact as well as a repository of crowd-sourced eruption times. One thing I noticed on the last visit is that Lone Star seemed to have a few distinct modes of preplay. One is the hevy sloppy splashing and jetting from the main vent that makes you wonder how much it's going to take to get an eruption started. Another mode has quiet overflow from the main vent and intermittent spitting from other little holes on top of the cone, then it builds steadily into the eruption. (if there was a third mode, I forget what it is now.) My impression is that recovery after a major eruption always follows the first mode. And the second mode might be typical of recovery from a full-length (4-5 minute) minor eruption leading into a major. But I only watched a few cycles, not nearly enough to draw conclusions. Has anyone else noticed this behavior before? I'm pretty sure it is not new.

Times for Lone Star are seldom reported to the VC. There is (is it still there?) a log book at the geyser, and if it is there then maybe somebody entered the previous eruption time. Or not. Remember that Lone Star undergoes one or more minors before the major. But there are a lot of other features in that area. Explore, and enjoy. This e-mail gives me the opportunity to say this: many thanks for those who read through the manuscript of my new book, "Arizona Rocks!". I can finally announce that the book has finally gotten past the page proof stage and that actual publication is near. The editor says that she thinks it will be available for distribution sometime in January 2013. Yes! Actually next year! Yea. At last. Scott In a message dated 9/29/2012 9:25:27 A.M.

I would like to know when the eruptions are predicted for today (Satureday). I know that the interval is very close to 3 hours, and I want to minimize the waiting time when I get there. </blockquote> _______________________________________________ Geysers mailing list <a href="mailto:Geysers@lists.wallawalla.edu" target="_blank">Geysers@lists.wallawalla.edu</a> <a href="https://lists.wallawalla.edu/mailman/listinfo/geysers" target="_blank">https://lists.wallawalla.edu/mailman/listinfo/geysers</a> </blockquote></div>
