As I approached Porcelain basin I saw that Whirligig's pool was VERY LOW. ~5'. I just missed a full eruption. Walked down and the pool was filling but still had 4' of exposed red. Walked away figuring I had a long wait and was surprised when I got above Hurricane Vent to see Graceful and heard it ie @ 1839. Pool was NOT in overflow when it erupted! End 1841. |

NOTE to future researchers - Missing from the data here is a Whirligig minor at 0541 and a full eruption at 0633. Based on the YVO temperature trace, the interval information here is incomplete. These eruptions were disputed and deleted, but I believe they should be included, or at least a future researcher can make the choice to include them, or not, in their study of Whirligig, so I note them here. |

From this time the number of non-minors increased while there were hardly any minors. Also no minors between the last two non-minors. In previous years, an increase in non-minors while simultaneously the number of minors decreased, announced the arrival of a disturbance. |

Minors started to become more spaced out around 1500 January 17 and occurred roughly hourly by 1800. This culminated into the first non-minor since ±April/May 2020 at 0220 January 18. It has since had two non-minors before logger data was uploaded @ 1200. Previous disturbances featured Whirligig switching from exclusively minors to exclusively non-minors for roughly the duration of the disturbance. Therefore, my assumption is that there's a disturbance currently ongoing at Norris. |

Whirligig tried to start. The pool had a big convection and the rooster tail vent erupted for15-20 seconds, then went quiet and the pool dropped about a centimeter or less. No eruption from the main vent. |

It looks as if Whirligig has switched, without much of a transition, to an eruptive pattern consisting out of largely 'major'/'normal' eruptions since 0000 on 30 March 2019. |

Whirligig seems to have entered a phase with what seems to be very frequent minor eruptions (up to 6+ per 3 hours) and few majors (one or two or even none per day). This seems to have developed gradually since December 2. |

Since my last visit on May 13, the Green is gone, clearly visible from the museum. Closer inspection showed good refill action from rooster tail and the little vent on shore, no convection from main vent. YVO confirms one eruption, but the time stamp was so far off last fall I'd hold off on entering E times until we synch up the logger with a seen eruption. Let the games begin!! |

Both Constant and Whirligig have lots of water coming into them from above. Both were looking a little 'colloidal blue' in the centers of their craters since the heavy rains in late Sept. enlarged that twin runoff channel from near Pinwheel. |

No eruption for 10 hours today, Sept 01. There is a large thermal soil "delta" in the pool similar to that seen in April-May (when Whirligig had been dormant Feb 06-May 23 2014), with water still draining into the geyser from upstream of Pinwheel. The recent heavy rains may have played a part in this slowdown, and obviously the creation of the delta. Convection and action from the vents looked better on my evening visit than they did in the morning. Norris logbook/staff did not see an eruption yesterday, or a drained crater. YVO is currently offline so I offer this information until we know more.

8/18/1985 Summary of Whirligig:
From watching it on 8/18 & 8/19, etc. It has a near 2 hrs 30 mins interval (near-about). When it erupts – it erupts for about 3 to 4 minutes. The water in the back vent goes up to 4 or 5 feet at an angle in height and occasionally shoots it out 5 to 10 feet. The main vent in the pool center – shoots bursting water to 10 feet sometimes higher with the eruption making a sound like a helicopter/ locomotive. After it erupts it takes 1 ½ to 2 minutes for the pool to drain 2/3 of the way down where it stops & starts to refill again slowly. Then it takes 40 to 50 minutes about for the pool to fill slowly back up to overflowing. Taking 45 to 50 minutes from the start of the eruption- thru the eruption, draining of the pool, refilling of the pool to where it is (the pool) overflowing again. The rest of the time – near 1 hour & 40 minutes about the pool is filled w/water= till the eruption. The intervals between eruptions are near 2 ½ hours long. Big Whirligig and Splutterpot Geysers are directly connected. Both of the above usually go off at about the same time. Splutterpot Geyser then goes off & on real frequent during the time of Big Whirligig’s Eruption, then stops about 20 seconds after Big Whirligig not to erupt again for the next 10 to 12 minutes. Then Splutterpot continues its 5 to 6 minute interval till the next eruption. More on this later. |

9/15/1980 Whirligig Geyser – became darker grey as the day progressed. Turbidity, at least in part, was due to run off entering Big Whirligig from Blue Geyser, via Constant. During a Big Whirligig eruption - the water did not clear indicating muddy water was coming from below or, all the water leaving Big Whirligig was that which had flowed into the system from Blue’s run off. I suspect the first case. Temp not ie at 10:14 165ºF, while ie at 1104 - 184ºF |
