[Geysers] Grotto/Giant, July 24-30

The following is everything I have in my notebook for Grotto, Giant, and Oblong, July 24-30.

Just one note:  the data for July 30 shows a correction to the eruption time of Mastiff, which was reported in Mike Keller's post as 0229 (I'm sure this was a typo).  Mastiff started at 0237, about 9 1/2 minutes into the hot period.
