The plan was to get up early and head out to the Bijou Cage. Except when I got up, I saw that there was no report for Grand, but reports for other nearby geysers. So with a ten hour interval, it meant I headed to Grand first.<\/p>\n\n\n\n
I arrived to West Triplet in eruption, so I figured that I wouldn't have to wait long. I did have to wait a full Turban eruption interval before the One Burst Grand eruption. West Triplet continued after Grand had finished, and Rift erupted shortly thereafter.<\/p>\n\n\n\n

I saw some Bijou slowdowns and Mastiff surges, but it wasn't until I'd been there 1-1\/2 hours that Bijou paused and water appeared in Mastiff. The pause lasted 3m20s, with the minimal Southwest Vents splashes, and was followed by Catfish and Bijou roaring.<\/p>\n\n\n\n
Returned later to the Cage, and while there were some huge Mastiff surges, the only item of note was a short Bijou pause where Mastiff showed water, then rose about 10cm for about 20 seconds after Bijou came back on.<\/p>\n\n\n\n
Back at Grand, arrived in time to see the Turban Delay interval. Turban started slowly, but over the next two minutes, it got stronger, and Grand did not show signs of dropping. It finally booped a couple of times and the One Burst Grand Eruption started. It took Vent over two minutes to finally start.<\/p>\n\n\n\n

After Grand quit, West Triplet restarted, and continued on with what appeared to be a normal eruption.<\/p>\n\n\n\n
I had just got to Castle to untie my bike when it started to erupt. This was the first observed eruption since early yesterday, and probably two major eruption intervals. About four minutes in Castle quit for a couple of minutes, then restarted and continued on with another major eruption.<\/p>\n\n\n\n
Another wait in the Bijou Cage resulted in another Mastiff bathtub after a two hour wait. Bijou was off for 3-1\/2 minutes, with the water in Mastiff only getting to about 20cm below overflow.<\/p>\n\n\n\n
The Grand wait began well after sunset. Arrived in time to see a long Turban eruption, then the Turban Delay Interval. We heard Grand boil up and boop before an explosive start. The first burst was just over nine minutes, so a second burst was likely. This time, that second lasted well over two minutes, and had a false ending, then about ten seconds of more Big Sawmill splashing before the eruption was finally over.<\/p>\n\n\n\n
