[Geysers] Geyser Report Friday, July 13, 2012

[Barbara Lasseter]

It was overcast last night and much warmer this AM--in the low 50's,
where we have been seeing high 30's and low to mid 40's--increasing
rapidly of course once the sun comes up.

Several days recently I have encountered dozens of bicylists on my way
into or out of the park.  I wonder if the folks signing on for a high
adventure bicycling trip thru Yellowstone understood the cycling
conditions here--and how many demand a refund.

Regarding the "Grand Abort" event at the 1423 Grand eruption
yesterday, where Grand filled, overflowed in great volume, and had
what appeared to be aborted starts in boiling before dropping, I
understand that is referred to as a "Type 2" delay--Grand almost
erupts, then doesn't.   Turban had a 22* minute cycle (19 min, 22*
min, 20min, 18 min)--not a turban delay.  I could not see if vent
overflowed from my vantage point.  Grand never reached overflow after
20 min. on the subsequent turban cycle, then erupted 18 min later on
the 2nd turban after the event.  Many of you veteran gazers may have
known this terminology, but it was new to me, so for the sake of
others who may also have been unaware...
