Once again, headed out to Grand at dawn. Did see post-eruption steaming in Uncertain as I went past. I had to wait 18 minutes from my arrival to see the first Turban eruption, and based on the lack of overflow on the next Turban eruption, I would say I got to see a Turban Delay Interval.<\/p>\n\n\n\n

A half hour later, Castle could be heard erupting. It was clear when I crossed over, but by then it was foggy enough that only the top of Castle's steam column was visible. It was a major eruption, and the sound of the steam was loud since there wasn't any background noise from the road and all the other activities of the day.<\/p>\n\n\n\n

Grand finally erupted on the fifth Turban eruption after the Delay, and it was a steamy, but backlit One Burst Eruption. West Triplet started midway through the eruption.<\/p>\n\n\n\n

Then it was down to the Bijou Cage. Other than Bijou erupting away, nothing happened there for an hour. Then we got a strong Mastiff surge. Within a minute water was visible in Mastiff. Bjiou did not shut down, and barely slowed down. There was some spitting from the Southwest Vents, and thanks to the sun angle, water could easily be briefly seen in Feather. After Mastiff dropped, Catfish and the B-C Vent splashed briefly, and Bijou began roaring.<\/p>\n\n\n\n
On the way back from the Cage, I was leisurely riding my bike down from Castle when Tara Cross came racing past me on her bike. I realized that I had turned off my radio during the bathtub event, and looking over at Geyser Hill, could see the steam from the Indicator. I picked up speed and followed her and was able to get to Geyser Hill in plenty of time to see the Beehive eruption. Once again, the little opening at the bottom of Beehive's cone was spitting water about 10-15cm from the cone during the time when Beehive's Indicator was erupting.<\/p>\n\n\n\n
I went back out to Grand in the afternoon. Over a 2-1\/2 hour period, I got to see nine eruptions of Turban where the intervals and durations got progressively shorter. After a 15-1\/2 minute interval, there was a longer twenty minute duration, where Grand looked like it could erupt-- the pool was full and having small waves. But it dropped as Turban started. Twenty minutes later, West Triplet finally started erupting, and Grand took the next opportunity to also erupt.<\/p>\n\n\n\n
The One Burst Eruption lasted well under ten minutes, but once the burst ended, Grand refilled, and for almost 1-1\/2 minutes, water sloshed around the pool as if we might get a second burst. Then Grand drained, and Vent & Turban also quit.<\/p>\n\n\n\n

Forty-five minutes after the start of the West Triplet eruption, Rift also began erupting.<\/p>\n\n\n\n
The little bit of shade where the walkway narrows in front of Rift always attracts people who clog up the walkway. Today they brought folding chairs (and also were off trail in the trees) and forced everyone as tall as I am to have to duck under the branches of the tree.<\/p>\n\n\n

The partial lunar eclipse was a bust. At first there were clouds with lightning to the southeast, blocking the view. Then it rained.<\/p>\n\n\n\n
When I headed out to Grand, the eclipse had passed the mid-point. The clouds were thinning out, so it was hard to tell that the moon wasn't completely full. Out at Grand, it appeared that Turban was about to have a Delay Interval, when instead Turban started to erupt. The steam from Grand's pool didn't look like it was building to an eruption, so it was a pleasant surprise when it started.<\/p>\n\n\n\n
As with the afternoon eruption, the duration was less than ten minutes, and after a bit of a delay, Vent & Turban quit. I suspect that during those two minutes Grand was attempting to have a second burst, and failed.<\/p>\n\n\n\n

As we left, realized it had been 17 hours since Castle erupted. So waited a while, but Castle wasn't even sloshing. I decided to head in, and before I could put on my pack, the eruption started. For the first few minutes, Castle acted as if it was going to have a minor eruption, but after the seven minute mark, there was little doubt that it would be a major eruption.<\/p>\n\n\n\n
By this time, the clouds were all gone and the eclipse over. There was also a moonbow visible low in the steam and spray wetting down the boardwalk.<\/p>\n\n\n\n
