Yesterday afternoon was another Rift delayed Grand interval in cold and wind. At least the last snow shower was a few hours earlier while waiting for Giant.
Note how yesterday's Giant hot period's alternated durations between long and medium.
Overnight was clear and calm and cold. The moon set just as the east was starting to show some light, so it never got totally dark. The Grand eruption was with the moon only a few degrees above the horizon, and a moonbow/fogbow in the steam over the main runoff channel. Like yesterday, the eruption appears to have been delayed by Rift, or perhaps more accurately, West Triplet. And I've never heard of a Rift interval of less than 10 hours before.
This morning there was only a single hot period, at 05:56, lasting 4m46s, as it appears that Grotto is having another marathon (starting around 02:57). As of the mid-day Grand eruption, it's still erupting.

And nothing to do with geysers
Yesterday afternoon when I left my cabin to head out into the basin, I heard a noise to the left. Down the slope, about 20ft away, was a bison grazing away on the hillside.
While waiting at Grand, I thought I saw motion on the top of the hill. It turned out to be a coyote who ducked back into the trees.
