Got out early because there were no reports of any activity overnight. Arrived at Grand near the six hour mark, and the pool was full, indicating it had been more than a few hours since the previous eruption.
Caught a Castile minor eruption, then two Turban eruption intervals later got the One Burst Grand eruption. When I arrived at Grand, the boardwalks were clear, but were slippery with ice by the time Grand erupted.

Then it was time to revisit Artemisia to look for a part from my camera tripod that was last seen after yesterday's eruption. (I found it.) Also took the opportunity to record some video of East Sentinal boiling heavily.
By the time I arrived back in the cabin, the start of Beehive's Indicator was announced over the radios. So went out for a nice eruption with calm winds and a double rainbow.
Early afternoon I arrived at Grand to what was probably a Turban Delay interval. I didn't see enough of that interval to be sure, but all the other indications (long Turban eruption, no overflow from Grand on the next Turban eruption) were there. The Grand eruption may then have been the fourth after a Turban Delay. Turned out to be the first observed two burst eruption since the three burst eruption. The duration was less than ten minutes, and Grand made no attempt to have a third burst.

With Rift erupting, decided there was no point in going out for the next Grand eruption early. I finally arrived at about the eight hour mark, just after the end of the Rift eruption. The Turban intervals and durations were both short. Ten minutes before midnight, Grand suddenly erupted. The eruption was over before midnight. It appeared that there was no attempt at refilling and having a third burst.

On the way out to Grand, in the trees across from the signs near the store, was a bison. I didn't see it until I passed it on my bike. The bison never looked up, as far as I could tell.
