Geyser Notes

Went out to Grand a little early, and almost immediately caught a full range of the new sput activity. Not only was there a nice eruption of Sput D, but the feature back in the rocks, Sput F2 was splashing, while Sputnik was sizzling and Sput A was also bubbling. The only thing missing was that West Triplet was low.

Caught a couple more eruptions of Sput D, and these camein the middle of the Turban eruption intervals. These eruptions were not accompanied by the other sputs. Based on the way the sunlight was hitting the runoff channel and not sparkling, I'm assuming that West Triplet still didn't overflow.

We finally got a Grand eruption after a delay that included well over a minute of Grand having heavy boils and small boops. When it finally started, it took Turban over a minute to start. It turned out to be a two-burst eruption, nicely against the clear sky of a warm morning. Even more interesting was that unlike most two burst eruptions I've seen the last few years, Vent and Turban didn't quit.

Waited around afterwards to see what the sputs and West Triplet would do. Activity was pretty much the same as the day before. There was a strong West Triplet overflow following Grand, with only some small splashing from Sput D. About 15 minutes later, as Vent and Turban quit, there was another bit of activity from Sput D, with West Triplet overflow. After that, there were a few more periods of activity about every 15 minutes.

The first post eruption Turban was almost exactly an hour after Grand's eruption, and wasn't accompanied by Vent. It was about that time that the Sput D/West Triplet activity quit. At the time of the next Turban eruption, West Triplet rose a bit, then dropped, and that was it.

I came out a bit early for the next Grand eruption, and saw Sput D in action without any overflow from West Triplet. But the runoff was wet, so it had done something recently. It appears that Sput D is in sync with Turban, as it was erupting about midway between Turban eruptions. It didn't look like there was any West Triplet overflow these times, but hard to tell as once the NPS eruption window for Grand opened, the benches almost immediately became full.

Grand itself waited just long enough to make in an official Delayed eruption. Afterwards again there was heavy overflow from West Triplet and a short period of Sput D sputtering.

Went out for one final One Burst Grand eruption before midnight. Didn't have to wait a Turban interval, so not sure what happened prior to the eruption, but West Triplet's runoff was dry. After the eruption West Triplet overflowed heavily for about 6 minutes. Only a few times did it look like the upwelling might result in water actually being thrown.
