With a full moon and no clouds, it was time to catch Grand again. Only had to wait a couple of Turban intervals before Grand erupted. While waiting, could hear an elk bugling off in the distance.
We had just gotten back to the cabin, and hadn't even started to strip off the layers, when there was a call of "Beehive's Indicator" over the radio. So there no reason not to go over there for the eruption. Just barely made it, but the lighting was excellent with the moon behind the water column.
The next Grand eruption was interesting. It looked like we had arrived in the middle of a delay overflow, one of those early in the interval that lead to a Delay of more than just two Turban intervals. So it was a pleasant surprise when we heard an explosive start from Grand. Except that was it, no followup. It was perhaps the highest (two to three meters) and loudest boop I've seen. The pool then dropped, and three minutes later, Turban started. Again, this was early in the interval, so expecting to wait. So it was a bit of a surprise when the pool rose back up, and within a minute the real eruption started.
In the afternoon, it was back out for a third Grand eruption for the day. This time also it felt like we'd walked upon a Delay, but nothing happened this time. Two Turban intervals later we got the Grand eruption, so it was still a nice short interval. And we got a second burst. It was long, but not long enough to be noted. Most of that burst consisted of Big Sawmill activity, too.
Decided after that to do another bicycle visit, this time to Black Sand Basin. Well, we biked as far as Punch Bowl, and then went on foot past Black Sand Pool. It was pretty quiet, with only one large boil, and minutes between the superheated sizzles. At the basin proper, things seemed pretty normal. We arrived to an empty Cliff Geyser, which started erupting for real as we crossed the bridge over the creek. That eruption lasted long enough that we were able to walk back to the overlook there. There was also continuous play from what I believe was Handkerchief Pool, and from Spouter Geyser. On the way back we arrived at Daisy just as it was starting.
Finally went out one last time for another Grand in the dark. There were several groups of people already waiting, but fortunately, when Grand did erupt, it wasn't until well into the eruption that anyone tried to illuminate it. This was despite the fact that the moon had disappeared behind some thick clouds, and it wasn't that bright out. Of course as we were walking away, the clouds parted enough that we could get a backlit Old Tardy eruption.
