[Geysers] Geysers that Erupt in Series

[Jeff Cross]

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?)
