It was, I believe, Jeff Cross who posted this photo a few years ago. I note the GIP as undergoing either an eruption or a steam phase (no doubt, the end of an eruption) in my book, where I also state that the GIP was apparently noted as having small eruptions in 1878 when it was referred to as "Giant #1." One thing I've found a bit intriguing about this photo is that Giant itself appears to be somewhat late in its eruption, yet the GIP is quite strong. One wonders if action of this sort might actually have been common 90 years ago. And with that thought, given the obvious close connection between the GIP and the rest of the Giant Complex, perhaps the surprise is that we haven't seen such action in more recent years... In any case, those other steams could be from other, nearby vents, the liquid discharged prior to the onset of the steam phase, or ? Scott Bryan In a message dated 9/20/2009 5:27:18 P.M.

That brings up another question, though: If you look at the enlarged version of the photo, what are the two small steam clouds immediately to its right, partially obscured by cars? -------------- next part -------------- An HTML attachment was scrubbed...
