No eruption yet, seems like the same old ~50 minute cycles with no water in Mortar. River is now low enough to expose the gravel bar below Bottom Vent's runoff channel. |

Snow even across the boardwalk, angle ie, probably no overnight eruption, will delete if someone thinks otherwise. |

Angle pretty much on the entire time. Many River coughs (River on and off quickly). Gold was starting almost simultaneously with River. Generally disorganized. Did not see water levels come up in Bottom Vent or Lower Mortar during this period of time |

F&M was quiet about 1100 when I passed to look at Morning Glory. On return about 1108 Bottom vent was active and was occasionally joined by Lower Mortar. River came on about 1110 and the first splash seen in Main Vent was at 1112. For about 20 minutes there were occasional splashes in Main Vent, River was turning on and off and on and off. No activity from High or Gold. After AJ arrived we walked away and were about 2/3 of the way to Castle before AJ called F&M. All of this occurred in blowing snow storm. Sigh... |

Possible eruption time, ie, at this time. Steam coming from the right location (mostly right location at least), steam drifting in from the right. It is a possible eruption but due to the darkness, as well as the possibility of this being a post eruptive Grand, I am leaving as a note for now. |

Came down to F&M in time to check on it and saw upper mortar surging slightly over the cone with water coming out the crack. It had several of these surges. Likely the end of an event cycle. The next event cycle whenever that is will probably result in an eruption. That is probably not guaranteed though. |
