Went out to Grand based on a double interval, and got to see West Triplet in eruption from the bikerack (Seem to see a fair number of events from there.) Fifteen minutes later Rift joined in just as West Triplet quit.
That eruption lasted under two hours, and during that time Grand never looked like an eruption was possible. On the first Turban eruption after Rift ended, Grand had nice waves on the pool which ended just as Turban started. So not surprised that the next Turban eruption was similar to those of the previous two hours.
Well before the time the next Turban eruption was expected Grand started having strong waves. Grand booped for quite a bit before the One Burst Eruption finally started. That eruption lasted well over twelve minutes, with the last minute or two consisting of splashing intended to just prolong the wait for the end.

For the first time in several years, I was accosted by a golden mantled ground tree rat looking for garbage. I guess the predators have easier picking elsewhere this year.
Finally got down basin beyond the Castle bikerack and caught a Daisy eruption. Looked typical and normal with a duration of 3m27s.
After that went out for another first overflow from Grand. This time it took place only 4h24m from the Grand eruption, but once again took place during a Turban Delay interval, one lasting 30m29s.
With another Rift eruption extremely unlikely, not sure what that overflow behavior could mean, so went out to Grand a bit earlier than necessary. Did get to see an eruption of Uncertain start just as I passed by Scalloped Spring. At Grand, West Triplet had visible water, and Percolator was quiet.
An hour later, West Triplet started erupting, lasting almost 34 minutes. The first Turban interval after the start of West Triplet had Grand showing the first attempt at an eruption with some nice low pool waves.
We got the One burst Grand eruption two Turban eruption intervals after West Triplet's eruption ended. Unlike this morning, this one burst eruption didn't reach ten minutes.

One thing I've noticed with the Rift eruptions the last few days is that Belgian Pool and Crystal Spring have low water levels before the eruption, but by the time Grand has erupted after Rift ends, they are both near their full levels. They then drop back down by the next time I see them, including the times I've gone out for first overflow about four hours later. This behavior is different from my experience with Rift in the past, where both would be at a high level when Rift starts, and be low afterwards.
