[Geysers] RE: Short Early Grotto Postmarathon

[Paul Strasser]

One thing about these short post-marathons.  I've seen two types.  In one
there is no Grotto Marathon, but Grotto just sort of sloshes a bit, then
builds up strength and - by gosh - it sure looks like an eruption.  Then
Grotto fades away and stops after 25-30 minutes.

 

The other kind is what Scott (and previously moi) saw this year.  A full
blown Grotto Marathon, then a real Grotto start (big whoosh, etc.) then a
real Rocket.  Then a real stop.

 

Also, the one I saw (and I assume Scott also) this year took place at the
expected time for the true post-Marathon eruption - many hours after the end
of the marathon.

Shortest Grotto we recorded

7/22/95

Start 2:58

End  12:04  (Lew visual end 12:19)

556 minutes duration

 

Start 1513

End  1538

24 minutes duration

 

We both were there in the morning taking stupid notes about the marathon
pool and the eternal (I mean variable) spring.  Seems we spent the morning
watching them do nothing very interesting then we went to the hill. It seems
we were watching Beehive at 1551 that day.   So a Rocket would be possible
since no one would have been looking that way.  I do think that we went
through stuff with David and David and came up with the notion of a "false
marathon stop" with great glee.....(its even in our notes) what fun it was!

     I haven't seen anything like the short Grottos Scott and Paul
described, but it sparks a memory.  Whichever year (1997) the Johns were
conducting a Grotto study they noted a few times when Grotto erupted very
early after a marathon.  Sometimes only a few hours after the end of a long
marathon.  These eruptions were very short (less than an hour) and seemed
count as a little extra duration on the marathon in the sense that if you
added their duration to the marathon and counted the marathon interval to
the next 'real' Grotto it was about what the duration/interval formula would
have predicted.  None of these were seen that year so it's possible that
Rocket had strong, early eruptions in those too.
