[Geysers] Geyser Report 2/18-2/24

[Graham Meech]

Here is a summary of the geysers I saw last week.

 

Chromatic was in overflow all the time - Mike Keller reported on the
listserver that Beauty was in overflow on 2/11 so they switched over
sometime before 2/17.  I never saw Penta erupt and it had a snow bank around
it all the time.  Giant and Grotto group are covered in my other email.  I
saw Grand every day which was great but saw only 10 bursts during the 8
eruptions I have data on, burst count average 1.25..I hope it picks up soon!

 

Sunday 2/18

 

Borah Peak (or some other small geyser on the ridge above Beehive) was
active.

 

Grand erupted at 1544 T2C d=9m50s - West Triplet was in overflow but drained
11 minutes before Grand erupted.  Turban started strong but Grand's pool
dropped.  I think this is the strongest Turban eruption I have seen and
Grand's pool refilled and it erupted over 2 minutes after Turban started.

 

Daisy interval ~ 3h 26m.

 

Monday 2/19

 

Daisy intervals 3h0m, 2h51m, 3h3m, 2h56m - very regular.

 

Little Squirt was ie.

 

Grand 1349 T2C d=11m

 

Grotto Fountain was at 1433 but no Grotto!

 

Tuesday 2/20

 

Daisy interval 3h33m

 

Grand 1047ie 1C, 1736 T1Q d=11 (the only Q eruption I saw)

 

At Fountain group, Fountain had high water, Clep, Spasm and Twig were active
at 1350m Jet had a 9m interval and Super Frying Pan erupted 1407.
Unfortunately Fountain did not erupt before my Snowcoach left.

 

"Salt and Pepper" in Biscuit Basin were very active, erupting 1-3'.  The new
spring near the bridge was just a hot spring, no bubbling visible.  Avoca
had a bit more water than in September but still nothing like the picture
that Scott posted.

 

Wednesday 2/21

 

Daisy sightings were almost 10 hours apart, so I expect I missed some
eruptions.

 

Grand 0946 T1C d=5m15s, 1618 T (I couldn't see if it was one or two bursts
as the wind blew right towards me at Oblong where I was standing when the
second burst might have happened).

 

Thursday 2/22

 

Rift 0730ie

 

Grand 0743 T1C d=10m20s, 1424 T1C d=11m30s

 

Daisy intervals 3h18m, 3h8m

 

Little Squirt active

 

Plume intervals 62 and 55 minutes

 

Friday 2/24

 

Giant overnight so I spent most of the day on Geyser Hill.

 

Little Squirt still ie in the morning.

 

Daisy intervals 2h51m, 2h19m, 2h36m - noticeably shorter intervals today.

 

Plume intervals 54, 59, 53, double 1h55m (while I was at Grand), 57m, 58m,
59m, 58m - very predictable!

 

Dome active, intervals 26-37m all day, durations around 5m

 

Grand 1217 T1C d=9m30s

 

Bulger major 1140ie, d>=8m

 

2/25

 

Beehive 0805ie cam-time - I missed the only daytime eruption waiting for
Riverside down basin but this was the only day Beehive looked like it would
erupt when I walked by it earlier in the morning.

 

Wonderful early sunny morning Oblong eruption at 0815ns - I bet the webcam
steam clouds looked good this morning.

 

Grand 1114 T1C d=10m30s

 

There were a couple of Castle minors during the week.  Aurum was on short
intervals and I saw one eruption up close.  Arrowhead Spring was very low
and the geysers between it and Depression were very active- at least 3 of
them frequently active but I didn't see anything over 2'.  Riverside had
some short interval days and other long interval days making it a bit hard
to predict especially as only 1 or 2 eruptions were seen a day.

 

That's about it for the main geysers.
