Was quite surprised to learn that Grand erupted shortly before dawn. Had expected (and planned) on it erupting several hours earlier. The interval was so long that I suspected a Rift eruption, but when I got out there, it was obvious that Rift had not erupted overnight.<\/p>\n\n\n\n
So instead I spent some time taking videos in the Sawmill Group. Got to see heavy bursting from Spasmodic as it dropped, Oval Spring having good size bursting from the north (front) vent, multiple eruptions of Tardy, the end of a Sawmill eruption, and a Penta steamphase minor.<\/p>\n\n\n\n
Missed the start of the last item, as I was set up to record Bulger and Old Tardy (which ended up doing little to nothing), but quickly moved the camera over to Penta. Once that was over, it seemed like activity in Bulger did pickup a little.<\/p>\n\n\n\n

At first Uncertain was making lots of gurgling sounds, with an occasional visible splash. Then, quite quickly, Uncertain became quiet. That turned out to be due to it rising in the vent. We witnessed a couple of floods coming from the vent before one of them triggered the Uncertain eruption.<\/p>\n\n\n\n
After that, it was a bit early, but still time to wait for Grand. I wasn't paying close attention when I realized that Grand's pool was full and having small waves at the six hour mark. Got the camera started in time to capture a couple of the strong boops. As expected, the pool level quickly dropped well before Turban finally erupted.<\/p>\n\n\n\n
Three Turban eruption intervals later, we got a repeat of that performance. This time there were at least five boops, with several well over a meter high. Turban finally erupted just after the 25 minute mark.<\/p>\n\n\n\n
So once again we had to wait three more Turban eruption intervals. This time the pool filled early, around the fifteen minute mark, but did start having wavelets until several minutes later. Again, there was some booping from Grand, but this time we finally got the One Burst Eruption, which lasted well over eleven minutes, with Vent & Turban quitting within a minute, and restarting within another six minutes.<\/p>\n\n\n\n

Unlike the last few intervals, however, the wait for this One Burst Grand was short, only 6-1\/2 hours. The Turban eruption interval was not quite long enough to be a delay. Once again the eruption started with several boops. We heard the first one in the dark, 15 seconds before the eruption.<\/p>\n\n\n\n
