For a double interval, the wait for the One Burst Grand eruption wasn't too long or cold. The eruption itself was nicely backlit but otherwise undistinguished.

Decided to ride the bike over to Biscuit Basin for some photos. There were a fair number of people pulling up to the close entrance road while I was there. None of them actually got out of their vehicles or even turned off the engine.
Sawmill was in eruption when I went out to see Grand, and was still in eruption over five hours later. With a deep drain in progress, I started taking some videos of the area. Got Oval Spring having constant low pool surging, some Spasmodic northwest vent activity, and a Penta steamphase minor. By that time Sawmill finally stopped, so it was time to transfer attention to Uncertain, which started looking good during the Penta activity. Fortunately, it took its time. During the wait, I managed to record a couple of low pool, no overflow eruptions of Sawmill, and finally got Uncertain erupting.
By the time Uncertain had finished, it was time to move over to Grand. We were over 7-1/2 hours into the interval when Beehive's Indicator was noticed by the NPS. So once again, the benches at Grand emptied. The Grand eruption started right after the end of Beehive's eruption, but it was a nice but short two burst eruption, so most who had went to Beehive made it back. The eruption lasted less than ten minutes, and there was no attempt at a third burst.

When we arrived at the Fountain Paint Pots parking lot, there weren't any lights in the distance. We quickly got our gear together, and were about to leave when sudden there were lights and the sounds of people yelling. We hurried over and caught about two-thirds of the second Morning eruption of the year. It was nicely illuminated by several torches, and there was no wind, so Morning was not hidden behind Fountain and Clepsydra steam clouds. After Morning ended we stuck around for the Fountain eruption, which lasted about three quarters of an hour.
When we returned to the cabin, it was time for Grand. We had just arrived when Castle started to erupt. A few minutes later I heard some booping, and we got the One Burst Grand eruption. There was a slight breeze which helped move the steam away from our view. Unfortunately, it was another short eruption with no attempt at a second burst.

By this time Castle was in full steam phase, so we spent a little time watching it slowly die down.
