pool dropped probably due to less water from upstream - gross floaties and scum - algae in channels below nearly dried out |

full and overflowing but cold - flooded by waters from upstream probably Tree Island that is having huge bursts - algae still in channels but some has washed away due to force - That's a LOT of water flowing in |

No longer dormancy blue, different from October. Overflowing lightly and constantly. Light convection observed. Clear with just a tiny bit of colloidal blue very deep in the vent. no snow within a few inches of the waterline. |

No activity. No minors. The berm around the vent looks weathered like it hasn’t had a major in a while. Pool level never changed and I never saw any convection either |

Quiet - left channel with good flow - right channel is wet but not steadily overflowing - upon arrival it looked like it just regained ovfl after a minor but stayed the same for 2.5 hours - as Constant heated up prior to erupting poor Whirligig looked cold in comparison |

Perhaps a very weak minor. There was stronger overflow, some churning, and the rooster tail vent bubbled. Nothing went airborne |

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. |
