[Geysers] Geysers that Erupt in Series

[Paul Strasser]

Daisy erupted in series from about 1973-77.  They were technically
Daisy/Splendid series, with both erupting for 1-12 eruptions in total, then
they were dormant for 6-20 days.  Since 1978, though, Daisy has been the
"normal" geyser, with splendid series as the rare and wonderful exception.

I don't consider Grand's burst to be a series.  Nobody ever calls each burst
a separate eruption, like Giantess or Lion (those are how I'd define geysers
that erupt in series).  So too with F&M and Great Fountain; they're in the
same non-category as Grand.

Jeff may dispute this, but nobody - repeat: nobody - considers Flounder's
2nd burst a separate eruption.  IF it was, what was the pause?  How much
overflow did it have?  You can say the same thing about Grand's 2nd burst -
was it a T or G?  And F&M after the initial 15 minutes - did the second
eruption "start" after a river vent pause?  

More Geysers with REAL series: Kaleidoscope, Deep Blue, and #'s 12 and 13.
Also Jet.  There are probably a half dozen more in the Kaleidoscope/Gentian
area.

Also White Pyramid, 2-3 eruptions about an hour apart.  

Darn, there was something in the Myriad group that I swore had series, but
none comes to mind.

I would like to know what percent of geysers in Yellowstone erupt in series.

I would like to solicit the opinions of everyone on this list.  Do you agree
with my assessment of whether the following large, well-known geysers
erupt in series?

Old Faithful (no)
Beehive (no)
Lion (yes)
Giantess (yes)
Castle (yes, it has minors)
Grand (yes, though we call them bursts)
Giant (no)
Daisy (no)
Splendid (yes)
Riverside (no)
Fan and Mortar (yes, the eruption pauses after about the 10 minute mark)
Artemisia (no, usually)
Great Fountain (yes)
Fountain (no)
Morning (no)
Steamboat (no)
Echinus (no, not usually?)
