[Geysers] Geyser Report 1/15/05

[Mike Keller]

Pat,

The timing of the hot period starts with the first vent to begin erupting in
front of Giant's cone.  Usually this is Feather, but it can also be Rust or
the Southwest Vents.  The key is knowing the activity of the Platform
Vents-sometimes the Southwest Vents will spit on and off several times but
never truly start, or start 30 seconds after Feather is on.

Your comments on a Bathtub are basically correct.  Mastiff will fill to a
point an inch or two below overflow.  Vents in front of Giant's cone will
overflow and the Southwest Vents will sputter, but no hot period takes
place.

I will write this up in more detail.  Look in the February or April SPUT for
more info!

Mike, or anyone, my understanding is that a Giant Hot Period starts 
when Feather erupts--correct? The clock, timing the hot period, starts 
with Feather?
And--Bijou off, no Feather, but water rises considerably in Mastiff, 
this constitutes a Bathtub?
Am I over-simplifying it?
Clarification appreciated--thanks!
