The previous day's late evening Grand turned into the after-midnight Grand. It turned out to be quite nice.There was a bit of a breeze from the south, which was pushing the steam to the north. The moon had just risen, so even though only about half, it was illuminating the pool of Grand and its runoff nicely. I was able to see the waves build on the pool and clearly see the start of the eruption. A second burst would have been really pretty, but that didn't happen.
I also got to hear Beehive just before Grand. It was perfect timing, as al the noise of Rift and Percolator erupting had finally subsided, making it obvious that something was happening over on Geyser Hill.
The morning eruption turned into the noon-time eruption, thanks to a Vent delay just as West Triplet had it's early window eruption. Again the lighting was nice. As Grand's surges climbed, each one broke out of the shadow of the previous one's steam cloud, a nice effect. And again, we got a one burst so there wasn't a chance to see that happen again.
During that wait, saw one of the tallest Oblong Geyser eruptions I've ever seen. A massive surge was not just as high as the dead tree by Chromatic Pool, but appeared as high as the trees behind Oblong on Wylie Camp hill.
After Grand it appeared that Penta might try to erupt from a normal Tardy Mode, but for half an hour everything in the Sawmill Group just sitting there. When Oval Spring's pulsations didn't seem to change things, I decided it was time to leave. Penta didn't erupt, as shortly afterwards Spasmodic stopped overflowing and all the water levels dropped. Later that afternoon, Sawmill erupted.
This afternoon's Beehive eruption was a warning. After several weeks of Indicator durations around 20 minutes, this one was barely over 6, just enough time to get from the store parking lot to the Firehole river overlook. (This was my first daytime Beehive this trip from that vantage point.)
The evening was clear and pleasant, and I didn't need to bring out the nighttime gear. Grand took advantage of the early West Triplet eruption to erupt as soon as the next window became available. While waiting, I saw another Oblong eruption, this one not impressive at all.
