After not going out to last night's One Burst Grand Eruption, left at dawn for the next Grand opportunity. After a West Triplet eruption started, we got a Turban Delay Interval. That led to a short Turban eruption interval under 17 minutes, and then a Rift eruption that lasted about 13 minutes.<\/p>\n\n\n\n
Grand tried again to have another Turban Delay Interval after four Turban eruption intervals, but that interval came up about a minute short. Then there was a short, almost 16 minute Turban interval, which finally led to the morning's One Burst Grand eruption.<\/p>\n\n\n\n

For the first hour or so, there was a series of Fan vents splashing, sometimes fairly strong, alternating with nothing happening. Then Upper Mortar rumbled a couple of times, That's when Bottom Vent started to splash, and High and Gold became strong, tall and non-stop. When Fan's vents finally quit, that's when Main Vent started splashing. Most of the splashes were the small, just visible variety, but there were a few strong, noisy bursts that filled the crater. That activity lasted for well over an hour, and continued up to the time I left.<\/p>\n\n\n\n
For the afternoon Grand, the wait was until West Triplet was ready. For almost the first two hours, nothing the Turban eruption intervals were a bit long, but otherwise uninteresting. Then there was a Delay Turban Interval lasting well over 30 minutes. Three Turban eruption intervals later, we got a second, even longer Turban interval that also ended in a Turban Delay interval.<\/p>\n\n\n\n
Finally West Triplet started to erupt, and twenty minutes later Grand filled nicely and we got a long One Burst Eruption where Grand actually started on the early side of the Turban eruption interval.<\/p>\n\n\n\n

It must have gone through the Sawmill Group or followed the river past Liberty Pool to get there. It continued onwards, crossing the river and was last seen headed for the bike trail.<\/p>\n\n\n\n
Afterwards, based on a sunset eruption prediction for Great Fountain. Unfortunately, the sun disappeared behind a cloud bank even though it had about 15 minutes remaining before dropping below the horizon. But the Great Fountain eruption was strong, with a number of noisy, fairly tall looking jets. The first burst ended and we left before it got too dark.<\/p>\n","protected":false},"excerpt":{"rendered":"
