Overall, F&M were having long cycles.
Bottom Vent and Lower Mortar showed water splashing on many cycles. Upper Mortar grumbled or roared on some of the cycles, and water was seen occasionally. Fan had better water levels than were seen on previous days. Angle often came on or splashed before Gold came on. Main Vent was steamy at times, and we heard a couple of roars. Only one small splash in MV was seen. |

No event cycles during this time. All cycles were well organized with River on before Gold on before Angle on and Angle turned off each cycle, usually within 10 minutes of River turning off. Main Vent steamed a lot but never had forced huffing or splashes. A couple of cycles had good water levels as long as 14m after Gold turned on but most did not. Upper Mortar only splashed once in the cone on the strongest cycle. |

Water in the UM catch basins and no rain recently (snow on evening of the 7th was the last precip). Unknown when it may have erupted but water was reported present this morning. Probably from the eruption late on 6th from the monitor. |

observed what appeared to be a regular event cycle, including 9 min full eruption of bottom vent, accompanied by much splashing in main vent with eventual normal turn on of river at 11:56 high gold at 11:58 Angle at 12:09, the vents off at 12:14 |

I don’t think F&M erupted recently. There is still a full snow coat on the boardwalk and some snow patches between the boardwalk and Fan. As for Link there is also snow below Link so it can be ruled out. Maybe it was Riverside this morning. |

There was a large steam cloud observed on the webcam that was in the general area of F&M. Really hard to tell, with the white skies and -2 degree temps, what it is. But we don't generally see steam at that location and the distance, angle are correct for F&M. I will attach a screenshot, captured late @ 9:10, but still seems extra steamy there.
EDIT: After an in-basin observation from Steve and subsequent eruption of riverside, I would probably lean toward this steam being riverside in the mist. https://geysertimes.org/note.php?id=13970 |

On arrival, BV channel wet 1/2 way down. High had thick bursts to 2’ & Gold thick bursts to 1’. Angle appeared at 1619 (but may have started before I got there). At 1620 H & G dropped, and MV had copious steam. 1625 MV roar, 1624 audible steam Upper Mortar. 1627 H & G thick again briefly but not as tall. |

Arrived to see a healthy jet of water coming from River, a fairly tall High Vent ie and a tallish nicely pooling Gold Vent ie, and Angle Vent was also playing. All vents waned at 1124 and finally fully turned off at 1206, except AV. During this time of quiet, MV and Mortar steamed, but not with force. All the vents turned on at 1215. Angle never fully stopped blipping. The fish are still jumping. The picnic table is still in place. Maybe next year. |

1240 R & A ie. 1244 R off, A continues. BV a few very light drops & mild MV steam. 1248 R/H, 1249 G & A. Very quick cycle. (My experience with spring mode is long organized cycles.) There is a very small “pool” of water immediately to the left of BV. River a bit high & somewhat muddy. |

still no indication that it is ready to wake up. River seems low enough but poor water levels and "garbage" cycles dominate minor activity as it has over the last 2 weeks of occasional observation |

Yesterday, Fan and Mortar were having short, organized cycles (and at least one event cycle with significant Main Vent splashing, which is more promising than what I usually see this time of year). Today I observed Fan and Mortar from 0930-1945. Though I left for a couple periods, I believe I only missed two cycles. Cycles today were longer and less organized than what I saw yesterday. I only saw one "event" all day: it started at 1238 and it consisted of Main Vent splashing prior to a cycle start followed by one small MV splash after River came on. Otherwise the cycle was unremarkable (no pauses, little activity from Mortar, mediocre water levels). After that, the cycles were all long (River on for 1 hour or more) and boring except for the last. The last cycle was a regular cycle, though Main Vent steamed heavily prior to River starting and Bottom Vent and Lower Mortar had higher water levels than prior cycles. River and Gold came on almost simultaneously at 1907 and had much better water levels than what I'd seen previous. High and Gold had periods of jetting up to 4-6 feet that lasted for up to a minute. Water levels waned prior to Angle on at 1923, but the sudden increase in energy was still a positive. It will be interesting to see if Fan and Mortar continues its usual spring slumber or if it's working back toward having eruptions. |

At F&M I just watched three quick junk cycles. River, then High and Gold after a few minutes, then all off after a few minutes, then maybe five minutes off before it all repeats. |
