I knew that Grand had erupted with Rift still erupting, so figured the interval would be on the long side. Got out there around the eight hour mark and ended up waiting another 2-1\/2 hours before we finally got the Grand eruption. Because of that, there wasn't the earlier fog and steam, making for a nicely backlit eruption.<\/p>\n\n\n\n
Grand took it's time getting going after Turban started. It quit quite abruptly, a good sign, and we got a second burst. The eruption was so short that we could have easily gotten a third burst, but through the steam we could see no attempt for the pool to refill.<\/p>\n\n\n\n

It was another Turban eruption interval later, a longish 4h50m, consistent with other first overflow times I've observed the last couple of weeks.<\/p>\n\n\n\n
Got out to Grand in the last afternoon expecting too see West Triplet and the Rift erupting. I was mostly disappointed. Instead we got a series of shortening eruption intervals from Turban, ending with an early fill on Grand and a short Turban eruption interval.<\/p>\n\n\n\n
Then Grand took nearly two minutes to start. At the beginning, the pool looked like it needed to fill more, and it did, then the waves started, and got increasingly stronger. Well past the minute mark Grand had strong convection over the vent, then boiling, then some booping, and finally the eruption started.<\/p>\n\n\n\n
The length of the first burst was more typical of a One Burst Eruption, but we did get our second burst. Considering the length of the first burst, this time I did not expect any attempt at a third.<\/p>\n\n\n\n

West Triplet started erupting shortly thereafter, so I stuck around to see if it would trigger Rift. It didn't, but A few minutes after the Vent & Turban restart, Grand started having fairly good after play. Some of the burst were thick and five to seven meters high. Something to consider when there is a Continue instead of a Quit is to stick around and see what the afterplay is like. An afterburst is most unlikely, but even and attempt would be welcome.<\/p>\n\n\n\n
Finally, just after dinner and well after sunset we got an eruption of Beehive while it was still light enough to not need any artificial lighting.<\/p>\n","protected":false},"excerpt":{"rendered":"
