At first I thought the overnight Grand interval was ten hours, and I had no reason to head out. Then I woke up and redid the math, and decided a twelve hour interval was worth investigating.<\/p>\n\n\n\n
I expected to walk up to a full pool, and I did. So much for seeing fog rising above the fog on the webcam. In any case, it was a Turban eruption interval later that we got a Delay that lasted over 33 minutes.<\/p>\n\n\n\n
A quick check of Economic showed it to be well below overflow, at the level of the inner rim. There also weren't many puddles in the runoff, and the area beyond the boardwalk was dry.<\/p>\n\n\n\n
But like last night, there was only a two Turban eruption interval delay, with the explosive Grand start actually visible due to a slight breeze from the north. Grand ended at exactly eight minutes, followed by a half-minute long pause before the second burst. At 1m07s, that burst wasn't long enough to constitute a Long Burst. About 45 seconds after the end of the second burst, it appears through the steam that Grand was full and starting to push out water. That's when the activty of Turban and Vent picked up, with Vent blasting away. No third burst, and a less than ten minute long Grand eruption ended with Vent & Turban quitting.<\/p>\n\n\n\n

There were some periodic Jet eruptions after our arrival, and a half hour later Morning's Thief erupted. I always remembered it as being tall and narrow. This eruption was tall and wide, with much overlap of Morning's pool.<\/p>\n\n\n\n
Fourteen minutes later Fountain finally erupted, with two more of the wide and tall Morning's Thief eruptions. Fountain lasted only 28-1\/2 minutes. I tried to take video of the whole eruption from the first Morning's Thief, but the wind was directly toward the overlook. And it was cold so there was plenty of steam. Now that it actually is an overlook, will have to try again under better conditions.<\/p>\n\n\n\n
In the afternoon we watch ten eruptions of Turban before we finally got a One Burst Grand Eruption. Every one of those was similar to the preceeding, the only change was that the intervals between Turban eruptions got shorter. After the sixth Turban eruption, West Triplet started to erupt. This is the first time I've seen West Triplet have a normal erupion lasting about 1\/2 hour that wasn't associated with eruptions of Grand or Rift. At least the One Burst Grand eruption lasted over 11 minutes.<\/p>\n\n\n\n

And after dinner, Beehive erupted. The wind cooperated and no one on the walkway got wet.<\/p>\n\n\n\n
The sky was clear and the moon was beyond the first quarter, with the temperature already in the upper 30s. But only had to wait a couple of Turban eruption intervals before the Grand One Burst Eruption started. Once again, it was a short eruption, at 8m41s, and there was no attempt at a second burst.<\/p>\n\n\n\n
