The next eruption was a major. A woman I met at Whirligig stayed after I left and later showed me the video on her phone. Definitely a major and she estimated the duration to be around 4 minutes. |

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 |

09/29/1979 Caught the Whirligigs in dual eruption again this afternoon. Big Whirligig was in eruption at 1642. At 1645:45 Little Whirligig joined with a continual splashing eruption. Big, feeling the affects of its competitor, grew in vigor, sending at least one burst 15 feet high. At 16:47:10, the Splutter Pot joined the confusion. Big Whirligig quieted down at 15:52:50 (7:05 in L.W.’s eruption) with only the rooster rail splashing afterwards. When Big quit, Little had a more typical individual bursting pattern. Little Whirligig ended at 16:55:20 for a duration of 9:35. It drained in 1:50. Big Whirligig quickly drained to 2 feet down in the vent. Africa was very quiet during the show, but grew in vigor as soon as Big Whirligig quit.
As of 18:00 neither had erupted again. |

09/23/1979 Caught the Whirligigs in dual eruptions this morning. First time I’ve seen this occur. Big Whirligig started with a five minute lead, the Little Whirligig joined in at 1057. Little Whirligig was weak in the beginning and continuous. Then became more powerful as Big Whirligig grew to the strongest activity I have seen. Big quit and Little quickly followed suit, the whole show ending at 1102. |

06/22/1978 It seems that when Little Whirligig is active for long periods Big really drains low, similar of course to what happens with Big W is the dominant geyser.
So far this summer Big Whirligig has been the dominant geyser. It sill be interesting to see if the roles will switch like they did last summer. |

05/30/1977 The Whirligigs are hard to figure. Sometimes Big Whirligig erupts for a long duration > 10 mins other times for only a couple of minutes. Sometimes there’s a comparatively long interval other times it’s more like like last year. Little Whirligig is similar, I’ve seen it several times a day and other times not at all. Still haven’t found a pattern to their activity. |

08/31/1976 Big & Little Whirly & Constant are behaving as never before!
Big Whirly has been erupting nearly constantly for 1½ hrs (since 1136). There are short pauses between eruptions, but the “tail” keeps going during the pauses. Little Whirly has been erupting along with B.W. It sometimes goes 7-10’ hi, but usually just splashes. Constant was erupting to heights of 50 feet (!!) & on three occasions B.W., L.W. & Constant were all erupting at once. Usually, B.W. would be erupting, Constant would shoot up 4 good bursts & L.W. would drain. Constant has been erupting every 15 min. |

Watched Big Whirligig go through one complete cycle. After erupting and partially draining it begins to fill. As it fills water comes into Little Whirligig until there is a pool about 8’ across. When Big Whirligig starts to erupt the water drains from L.W. Just as B.W. began. Constant gave one half-hearted burst. Will has to see if this pattern is typical or unusual. |

All Porcelain Basin markers were in place at 5:45 pm except at Big Whirligig, there the marker placed in the basin was washed away, the marker in Big’s runoff was still in place thought runoff area was damp; it appeared that basin must have filled (not quite as full as before – perhaps a couple of inches short) and run over a bit but not with great force. Marker in basin replaced. |
