Waited for the rains to end before heading out for the morning Grand. West Triplet started erupting as I arrived, followed by Rift. That was when Grand had a late fill and a long Turban Delay Interval. Ended up having to wait two hours and six Turban eruption intervals before the One Burst Grand could occur. On leaving, I noticed that Belgian Pool was perhaps as high as I've seen it this visit, with water well into the side lobe.<\/p>\n\n\n\n

The Southwest vents poured out water. This event lasted about 3-1\/2 minutes.<\/p>\n\n\n\n
Later that afternoon there was another Mastiff Bathtub where the pause lasted 4 minutes, but Feather only overflowed, and the Southwest vents didn't do much.<\/p>\n\n\n\n
I did leave the Cage to go to Grand, where once again I got to see West Triplet erupt. It was a half hour later that Grand again had a Turban Delay Interval. But this time, it took only two Turban eruption intervals to lead to the One Burst Grand eruption. This one had a false pause lasting several seconds at around the eight minute mark, so not surprising that there wasn't a second burst.<\/p>\n\n\n\n
