Sat a while this afternoon. Angle wild phase continues with short cycles and not much in the way of bottom vent or water levels. Did get a bottom vent / lower mortar water cycle with a 30+ minute off at 1924 with G taking ~4.5m to turn on, but not a lot came of it when it counted. Still wondering whether anything even matters right now, or whether it will just spontaneously decide it's time. |

upon arriva, River, High, Gold and Angle were all splashing. H 2 - 5' at times. Angle disappeared for 8 minutes or so and H and G kept erupting with variable levels. Deep and loud rumbling from Mortar. I don't remember it being so loud in years past but could've been. By 2320, Mortar was much quieter and Angle alone was schczing schcz ... schcz .. schchcchcz. Unattended. |

Are you a gazer? Do you find event cycles too exciting? Love angle? Then this interval is for you. Nothing encouraging seen today as of yet water levels have been uninspired. |

Angle wouldn’t quit during this observation period. Nothing encouraging seen, water levels were pretty mediocre overall no attempts from high to go steady. |

Mostly short, disorganized cycles with poor to mediocre water levels, Angle on and off almost at random, no Frying Pan/Back vents. Bottom Vent spritzing and very low water in Lower Mortar when River was off. Some huffs from Main here and there. |

Fan's minor vents on from 1205 to 1250, Angle continuous after River shut off. Low water in Bottom at 1305, runoff channel bone dry other than a couple small puddles just below BV. Runoff channel with lush bacterial growth next to Angle looks mostly unchanged. River back on at 1310. |

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. |

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. |
