[Geysers] Giant in 2006 (Stephens)

[lynn stephens]

Thanks for sharing your list.  

#164  Mike Keller reported the signs washed sometime between 4/1 and 4/8.  Based on observation of the platform, he estimated it had erupted two days prior.  I believe that was based on the type of recovery seen earlier in the year.  As we found out the week of April 17, the recovery pattern changed sometime prior to the third week of April, and possibly earlier than that.  Hopefully the electronic monitor will give a better date and time for that eruption.


#165  Paul Strasser reported on the listserv that the signs were replaced by Katy.
#168  The signs were replaced on 4/23.

#169  M. McLean's email on 4/28 said

>On 4/27 I went out to watch for a marathon recovery hot period and the signs
>were washed (Replaced by Katy Duffy and Patrick Matheney last night) 

Since he found the signs washed on April 27, I assumed "last night" meant the signs were replaced on 4/27 since he put "Giant info 4/28/06" as the subject line.   Also, Paul Strasser posted an email on 4/28 saying he had "just talked to Denise "Denise at the OF visitor center.  She told me that Katie replaced the signs on the giant platform yesterday." which would indicate the signs were replaced on the 27th after Matthew found them washed.

#168 and 170:  Because the solo Mastiff eruptions were unprecedented, I've included notes about the solo Mastiff eruptions on 4/22 and 4/29 in the list of Giant eruptions that I am keeping.

I'm sure all of us keeping lists will scramble to update them when/if the next electronic record becomes available.  

Not related to Scott's chart, but since I'm writing about Giant:

Speaking of Mastiff eruptions, Mastiff erupted prior to the Giant eruption on April 23, 2006.  But the only two signs that washed were the Giant and "Danger" (which is getting really beat up from all the rolling off the platform) signs.  The Catfish, Bijou, and Mastiff signs did not wash.  I've always been somewhat uneasy about statements speculating on whether or not Mastiff did or did not erupt prior to an eruption of Giant based on the signs that did or did not wash off the platform.  The events of April 23 cemented my unease about concluding that Mastiff probably did not erupt because some of the signs did not wash.
