[Geysers] End of Season reports

[Stephen Eide]

Greetings and Salutations,

I have a few reports from the end of the season for the week of November 1
to 7 2010.

First for Black Sand Basin, most of the basin is normal, or at least as much
as I could tell in the short time I was there.  Spouter and Cliff were
normal.  Ragged and Jagged springs did erupt, but they were just a few feet
high.  UNNG-BSB 2  was not erupting.  I did see it do a weak intermittant
overflow but that was all.  If the interval was long enough I would have
missed it however.  Handkerchief Pool, Handkerchief Spring, and UNNG BSB-5
were all active.  Unfortunately, Rainbow pool and Sunset Lake were not
active.  Cinnamon Spouter was a perpetual spouter as usual.  The springs
under the boardwalk to Sunset Lake continue to be active, maybe a bit
bigger.  The little spring to the East of the Boardwalk half way to Emerald
Pool was boiling/bubbling with continuous overflow.  Nothing was seen from
Sunlight Geyser or UNNG BS B-1.  The steam vent between Spounter and Iron
Creek is still active but weaker than it was this spring.  Whisler is still
dormant.

In Biscuit Basin Rusty Geyser is still a dependable performer.  Dusty Geyser
is still dormant.  I did look at Ralph Taylor's data on Mercury Geyser
(thanks Ralph), it appears it is dormant for hours to days, then  is active
for several hours, but not at all dependable.  The pool of Black Diamond is
now at the same level as the pool of Black Opal.  I think it has washed away
the ground between the two pools.  Shell Geyser is active.  Both Jewel
Geyser and East Mustard Geyser were active with intervals of about seven
minutes.  Avoca spring was still having intermittant boiling periods about
one a munute but the height was only about a foot or so.  I saw nothing out
of the Silver Globe group.  I saw Outpost Geyser in the area to the north
but nothing else erupted while I was watching.

In the lower geyser basin Fountain continues with eruptions about every six
hours.  Morning's Thief continues to join in with one or two eruptions
during the first few minutes of Fountain's eruption.  I suppose there could
be times when it has three eruptions but I only saw one or two eruptive
periods.  Spasm usually but not always erupts before Fountain sometime
before Fountain starts.   Twig sometime starts during Fountain's eruptions.
Jelly was clear all the last week so there was no evidence of any eruptions
from Jelly.  Nothing from Sub or Old Cone either.

In Serendipity Meadow UNNG SDP-1 was active with intervals of about 40
seconds and durations of about six seconds.   The spring on the southeast
end of the meadow is acting as a geyser with intervals of one minute,
durations of 23-30 seconds and heights of about a foot or a bit more.  Lemon
spring is quite hot, a beautiful light blue color with steady overflow most
of the time however one time I drove by and Lemon Spring was a few inches
below overflow.

During the week I saw Botryoidal, A-0 and Filial all erupt.  I saw Logbridge
bubbling but did not stay around to see the eruption.  Great Fountain was
coming out of wild phase and had several days of overflow and drop, overflow
and drop activity.  Finally when it did start erupting it went into an
interval of about 11 hours however the period of overflow before the
eruptions were longer, in the two hour to two and a half hours of overflow
before eruptions.  I did see a series of Gemini once during the week on
11-7-10.  The interval on Pink Cone appeared to average just under 24 hours
but the range appeared to be in the 21 to 27 hour range.  Most of the first
part of the week it was erupting between 0800 and 1230 but by the end of the
week it was erupting before 0800.  I heard reports of Pink Geyser and
Narcissis but did not see them myself.  Bead Geyser and Box Spring were
active also.  Artesia is erupting with rare eruptions to 15 feet but most
are only a few feet high.  Last year on closing week Artesia was frequently
active to 15 feet on most eruptions.

The Kaleidoscope group was mostly quiet, or perhaps mostly screened by
Clepsydra for the week.  In any case I saw very little.
