Thanks, Wasabi that is the White Dome Geyser and it eruped 4 or 5 times before the Great Fountion which as a 12 to 14 hour cycle. The park service gave a ETA of 6:30 PM to 10:30 PM on the day I was there and it went off a 8:45 and sunset was 25 minutes later.

Great photo, thanks. There seems to be some sort of minor eruption in the background, one half way up on the right side???
Are you going to post some of the ones you took of the eruption?
