[Geysers] Pre-Giant Grotto info

[Ralph Taylor]

I downloaded Grotto's logger not long before the Giant eruption of 22
September.  The activity for the week was as follows:

20/Sep/06 20:55:00	34:50:00	25:26:00

The recent pattern of a "mini-marathon" [no, I don't want to debate
nomenclature!!!] followed by "normal" short duration eruptions followed by a
"real" marathon [around 24 hours duration] applied.  Sort of.  There were
TWO long marathons, not one.

For those keeping score at home the 19-hour eruption of 19 September ended
at 0553 on the 20th (electronic) and the 25+ hour marathon of 20 September
ended at 2221 (electronic).
