When I awoke at 05:00 surprised to see an entry for Turban around 04:30. That meant that Grand probably hadn't erupted, and worth going out. It was just getting light and a bit foggy, but I arrived to find Grand still full at 9-1\/2 hours. There didn't seem to be any indication of a recent Rift eruption.<\/p>\n\n\n\n
I then got to wait through an hour's worth of short Turban intervals and durations before West Triplet started to erupt. A half hour later Grand finally got around to erupting, nearly an eleven hour interval. This time the Turban to Grand interval was more normal, and I was even able to see Vent overflow beforehand.<\/p>\n\n\n\n
Rift started erupting during the first burst. The Grand burst ended abruptly with a short duration well under eight minutes, but the second burst lasted over 2-1\/2 minutes. West Triplet was still in eruption as I left.<\/p>\n\n\n\n

The wind was uncooperative, and the duration of the eruption was only 3-1\/2 minutes.<\/p>\n\n\n\n
Then it was down to Fan & Mortar, where there was more activity that can look really good, until you realize that it does it alot. In this case, after being mostly quiet with just Angle erupting for about 40 minutes, High and Gold started. They quickly increased in height until High was going about 3-4 meters. This lasted about ten minutes, then quickly died down. After another ten minutes of just Angle splashing, I left the area.<\/p>\n\n\n\n
Got out to Grand at the six hour mark. Got to see a normal Turban eruptions and then a Delay Interval eruption. When I went out, I was hoping Grand would hold off a bit, having an eruptions between 14:00 and 15:00. That would set the next eruption up to be just after dark by a nearly full moon. As it turned out, the delay lasted for eight Turban eruption intervals, and it was nearly 16:00 before we got the One Burst Grand eruption. Once again, there were a couple of periods during the eruption where the jetting quieted down, and in decades past that would have resulted in the end of the burst. This time it seemed that Turban quit as Grand quit.<\/p>\n\n\n\n

Afterwards, went back to Fan & Mortar where there was another series of tall activity from the Fan vents. The first time it was just High and Gold, the second time Angle joined in, and they activity wasn't quite as high.<\/p>\n\n\n\n
Beehive's Indicator got called just before sunset, and the sun sat during the Beehive eruption. Unfortunately, the wind was in the wrong direction for rainbows. Instead the view was into the sun, but it was still interesting lighting.<\/p>\n\n\n\n
It was still a bit light when it was time to head out for Grand again, and wait for a moonlight eruption. On the way out had to dodge a bison near cabin 200 and a second one below the lift station. Arrived in time to catch the start of a West Triplet eruption.<\/p>\n\n\n\n
Unfortunately, that meant we got to wait for the next West Triplet eruption opportunity. Three hours later, after midnight, Grand finally did erupt, with West Triplet following within a few minutes. The first burst seemed too short for it to be the only one, and after a relatively short pause, we got another burst. About 30 seconds in, it seemed like the burst was stopping, but then it continued on for a total of nearly a minute.<\/p>\n\n\n\n
