I like heading out at dawn on a cleaqr, calm morning. Sure it's cold, but that also brings out the steam from every little warm hole.
This morning I knew that Grand wuold have gone well before I got out there. Unless, of course, it had a really long interval an, which would mean that I still made the right decision in not going out to wait for hours in the cold and dark. What I didn't want to see was Vent and Turban. I got my wish, as the pool was near but below overflow. I did see the overflow start at around 06:30, which put the eruption at around 02:00. Perfect, as that put the next eruption, most likely, before noon.
Another reason I was out there was to check on the Sawmill Group. Definitely wanted to catch a Penta if I could, and at first it looked like the group was going to oblige. Sawmill overflowed for a bit, then dropped, but Penta never really had the look of an immenent eruption. The surging over the bottom vents, though, was an encouraging sign that I might want to be around for the next cycle.
Since it was still early, I decided to take advantage of a loop around Geyser Hill. On a hot, crowded afternoon, Geyser Hill isn't all that pleasant, but in the cold morning, it's well worth the time. I did get to wait for an over 80 minute Plume interval, and saw a few new holes I hadn't noticed before, but otherwise, it looked unexciting.
When I returned to the Sawmill Group, I noticed that there was evidence of Churn eruptions.The gravel near the boardwalk was wet and there were puddles. Churn itself was well below overflow. But the group was rising, and again everything looked good for Penta. The water levels rose nicely, and as Spasmodic started to overflow and the back vent to erupt, Penta started to sputter from its main vent. A little while later, as the Penta pool neared overflow, the bottom left vent started to bubble heavily. Another good sign, I thought, until I heard some thumping over to my left. So much for Penta, as it's pool dropped into the vents within moments of Sawmill's start.
Turns out my guess for Grand's previous eruption matched the monitor time, so it was time to shed some jackets, reload the pack and head back out. On my walk back to the Sawmill group I noticed some fresh, wet dog-like tracks on the boardwalk among all the cold springs. At Grand we got to see the makers of those tracks, a pair of coyotes who failed in their attempts to harvest a marmot or two. One failure and they decided to move on.
The Grand eruption itself was very nice. What little wind there was pushed the steam an spray back onto the rocks and towards Rift. Considering that usually at that time of day the wind has picked up, and is blowing the steam to the north, it made for a nice backlit eruption without all the steam of early morning. And of course, Beehive's Indicator started during the second burst. Unlike yesterday, I decided that I'd had enough exercise for a while, and watched the eruption from the bridge. Again, the nice wind conditions made for an impressively tall column.
And then, what to do? Time to take advantage of the time to visit Daisy, then it's nap time. Today, perhaps thanks to the lack of wind, the Daisy intervals were a little over two hours.
The evening Grand was preceded by a not unexpected Rift eruption, but if Rift is having a delay effect, this time it only added about 45 minutes. During the wait we got to see a second Oblong for the day, an interval that was identical to Grand's: 9h17m. The one burst eruption was nice, thanks to the lack of wind and low sunlighting. At one point it was so calm that Grand had a small base surge develop and obscure the base of the water column.
The new Visitor Temple is at the stage where they are installing the insulation, so it's covered with white Tyvek making it look like a huge white plastic wrapped block. Or as Paul Strasser suggested, one of Christo's lesser attempts.
