Glad to see Giant erupted again today too!<o:p></o:p> <o:p> </o:p> The Giant/Grotto relationship appeared to be much like it was last summer with Grotto not always starting with the first Grotto Fountain eruption after a <st1:place w:st="on">Marathon</st1:place> and South Grotto Fountain independent eruptions when Grotto didn’t start. There were frequent long Grotto eruptions although I don’t know how many of them kept going all night long since I didn’t stay out to watch very late but it sure looked like they went long into the night. <o:p></o:p> <o:p> </o:p> Giant had frequent hot periods when Grotto didn’t go into marathon, Mastiff depth charged a lot and Bijou went into steam frequently. Oblong appeared to be the most changed, with less frequent eruptions – I didn’t see any 3-4 hour intervals and some were more like 10 hours long.<o:p></o:p> <o:p> </o:p> Here are the details from around Giant:<o:p></o:p> <o:p> </o:p> Saturday 2/16<o:p></o:p> <o:p> </o:p> Grotto 1228ie when I arrived.
