[Geysers] Trip report Oct 4-7, 2007

[Barger]

As far as I know, the Fan and Mortar marker was replaced on Sep. 29th in the 
AM.  The marker had been gone for a while and we believe that there might 
have been an eruption late evening to overnight on the 28th to 29th, judging 
by how the boardwalk was wet near Spiteful and only damp toward the bridge. 
(This was observed by Dave.)  I missed last week, due to the expected storm. 
I will be in this weekend.  Kitt Barger
