[Geysers] Grand Overflow

[Mike Keller]

Over the years I've seen it take anywhere from just under 3 hours to almost 6 hours for Grand to reach first overflow.  As Scott said below, most of the time it takes Grand 3 to 4 hours before first overflow.  The longer periods have always happened when Vent and Turban would have a 2nd restart following Grand, usually 60-90 minutes after Grand erupted and they would erupt for another hour.

First overflow about 4 hours the previous eruption is normal, and unchanged. I'd asked (off list) about this earlier this season and was told that this time-to-overflow was unchanged, despite the ridiculously short intervals.
