The moon was nearly full, but the sky and view seemed off, thanks to the considerable smoke still in the air. Shadows were faint and indistinct, and filled in from light scatter by the smoke.<\/p>\n\n\n\n
With Grand having erupted during Rift the previous evening, it was hoped that this next Grand eruption interval would be shorter than average. Instead, several Turban eruption intervals after arrival there was a longer Turban interval. It wasn't long enough to be considered a formal Delay, but it felt much like one. Afterwards, the next Turban eruption was accompanied by no runoff from Grand, also typical of a Delay type eruption.<\/p>\n\n\n\n
During the wait, I kept checking the weather radar map, because there was a small patch of showers that first appeared over Jackson Lake, and was slowly moving north. Every time I looked, it seemed like it was about an hour away.<\/p>\n\n\n\n
So it took Grand five Turban eruption intervals to finally have its One Burst Eruption.. Turban started well before Grand. By that time the clouds had started to move in, so the moonlight, combined with steam from the water column in windless conditions, made viewing difficult. No chance for moonbows.<\/p>\n\n\n\n

Didn't have enough time to make it out of the cabin area before the Beehive eruption started.<\/p>\n\n\n\n
Thanks to the longer intervals, Grand was finally going to have an eruption wait starting at a new time of day. West Triplet was in eruption, quitting without a Rift eruption. As it ended, Grand had a long Turban Delay interval. Three Turban eruptions later, we got another long wait as the pool slowly filled, but never started pulsations until the last minute.<\/p>\n\n\n\n
Even after Turban started, it seemed Grand was reluctant to erupt. The Vent overflow was well after Turban started, and then Grand had at least 15 seconds of Boops before finally erupting. The first burst lasted well under nine minutes, and there was a short pause. Then the second burst lasted almost two minutes. After the eruption, it took Vent & Turban, which quit, about twenty minutes to restart.<\/p>\n\n\n\n

Once again, this took place during an eruption of West Triplet and a Turban Delay interval.<\/p>\n\n\n\n
Made it back to the cabin just ahead of the first thunderstorm. The second one featured raisin sized hail that turned the area white, along with at least one lightning strike nearby, as I saw now flash but heard what sounded like a gunshot.<\/p>\n\n\n\n
The rains continued up to the time to head back out for the next Grand eruption, and I decided I'd rather not get wet for a One Burst Eruption, or even a two burst eruption.<\/p>\n","protected":false},"excerpt":{"rendered":"
