Observations for 02 July


I arrived just in time to have to wait a full Grand interval before the next eruption. But Beehive did oblige me by erupting with a less than 12 hour interval just as I was about to head out to Grand. With two eruptions per day, now it's jut a matter of it adjusting the intervals so we can have a few days with both eruptions in daylight.

The day was cool and blustery. I encountered some showers in Island Park which appeared to headed toward the Park, and they did get some showers around then, too. But it never again really looked like we were in for rain, and the wind helped keep the mosquitoes from attacking. The less said about the drive in from West Yellowstone, the better. Let's just say that I saw "animal jams" that involved no animals.

The Turban intervals at Grand were longer than I've been used to 21 to 23 minutes, at least until we had a early overflow and Turban had a short duration. Just before the second Turban, the one that I expected to have an excellent chance of leading into the Grand eruption, West Triplet started. Considering that Rift had erupted at dawn, I took that as another good sign. And it all was. It did take Grand almost a minute to build to the eruption from the start of Turban, with good waves then appearing.

The eruption itself had a nice full rainbow, thanks to a large break in the clouds. When the first burst lasted 10m44s, I was surprised to look at the pool and see water sloshing about. Not only did we get another burst, but it lasted long enough to make it a T2*Q. Vent and Turban did act at first like they wanted to continue, until suddenly Turban shut off and Vent quickly followed. The restart, while quick (about 7 minutes) had Turban taking its time, with lots of steam and noise and very little water in the first minute or two.

Tomorrow the Fan & Mortar window opens, more or less, which should take care of a lot of my free time. Reports today were that it was having actual cycles, as opposed the chaotic activity featuring Angle vent which was featured before the previous eruption. What that means we will find out later...
