From wc, pool still looks high plus you can track strong runoff to right {from wc perspective} and down hill from steam it is putting up. {I realize everything looks steamier when the day wanes, but still...} |

Observed from the webcam. No visible boiling (cam is zoomed out and there is too much steam to see when zoomed in) but pronounced steam rising from runoff channels both north and south. Dry conditions and relatively warm temps out - not really conducive for runoff steam. |

Boiling constantly, variable intensity. 5 6" boils, one was sustained nearly a minute at the NE rim. 1 1' boil at 1021 that led to activity on full northern half of the pool. Most activity on NxNE rim, but shortlived and weak activity viewed across the pool. |

Upon arrival, the runoff channel between Giantess and Teakettle Spring was wet down to the bottom of the hill (evidence of runoff overnight). Vault was at about mid-level, the same as it was 8/12/22. Most of the boiling events during the morning/afternoon were along the N and NW side of the pool (in contrast to the predominating N/NE and E boiling seen more frequently this season). Many wide boils seen throughout the morning. Most were about 6", but a handful were 1-2'. At 0919 a 2' N boil put heavy runoff out the N/NW side of the pool - enough to create a cascade of water down a jagged part of the sinter platform facing Teakettle spring. The best activity observed was in the half hour preceding Beehive's 1106 eruption. From 1027-1029 there was an extended period of N rim boiling that reached up to 2' and at times consumed large areas of the pool. At 1039 a wide NE boil that was 2-3 ft. put runoff out the N side of the pool. Generally impressive boils with moderate amounts of NW runoff continued until 1058, when I left after seeing Beehive's Indicator ie. Upon return at 1120, Vault had begun visibly dropping and the activity at Giantess had died down considerably. The one exception was at 1211, when a sudden NW boil 2' in height put a significant amount of runoff down the NW channel and again created a cascade along that side of the platform. No notable boiling events occurred from then until I departed at 1315. |

Constant boiling, mostly in north and northwest of pool. Averaging a ~6" boil every 1-5 minutes. Four boiling episodes over 1'. Poolwide boils fairly frequent, with a few energetic 6+" boils in center. Frequent gentle boil in Vault, only once sustained for more than 60s. |

Vault's water level rose since yesterday and continued to rise slightly through this observation period. 1352 - 1 ft. NE boil with some runoff. 1402 wide N rim boil with multiple points of runoff. 1410 - estimated 2 ft. center pool/S rim boil. 1418 - impressive center pool/ S rim boil that I believe reached 3 ft. It did not maintain that height for long, but it broadened, lasted for 1m+, and was wide enough to cover the east half of the pool for probably 30s. 1422 and 1423 - low, wide N rim boils with runoff. 1425 and 1427 - wide N boils with notable runoff. Overall, activity quieted down after 1430 except for a NE boil at 1452 that put substantial runoff over the rim. |

Consistent wide boiling along the north/northeast rim for most of the morning, typically at intervals of about 10 minutes. One boil at 0912 easily reached three feet tall, though it quickly died down and was isolated to the NE rim. The most active period was from 0930-1040, with at least three wide (though short in height) N/NE rim boils that put runoff over the edge of the pool between 0930 and 1000. At 1025 there was a NE rim boil up to about 15" that had some force behind it. At 1037 a NW rim boil put a moderate amount of runoff out that side of the pool. Except for the 1037 event, most boils seemed concentrated on the NE rim. |

(wc) From around 1029 onward... Numerous wide, long-lasting, and some decently tall boils. Lots of white water visible from the camera, and only a minute (often less) between boils. Posting this note in hopes that someone in basin was watching it around this time, it would be nice to know how tall these boils actually are. Most boils appear to be along N-rim |

(wc) The camera has spent a fair amount of time on Giantess today: Mostly small but very wide boils, a lot of them are only a minute or two apart. The biggest boil of the day was at 1418, similar to the largest ones in the past few days. A lot of the boils are along the East rim. |

Center-south rim two-point boil (wc) Smaller in height than the ones yesterday, but wider. Again at 2022 but smaller and pretty much all South (and east?) Rim. It would be nice to have some in-basin confirmation of how large these boils actually are. The camera was only on Giantess from 2020 to 2023. |

Giantess had 3 north rim boils that were 1-2 feet in height and sent water over the edge of the crater during this time. The runoff from the boils dampened half the width of the runoff channel near Teakettle Spring. |

Again, from Obs Pt with binoculars, in the past half hour when the wind died down, good convection was visible over the vent, and there was one more north face boil sustained for about 15 seconds with water pushed out forward and to the right. Just sayin'... |

From Observation Point with binoculars. Over the past half hour, there have been 3 short episodes of North face boiling with of put out the front, then to right and left. Pool had episodes of low but vigorous boiling, although the appearance of agitation was helped along by strong wind. |

(wc) Very impressive boils over the last little while. None of them were exceptionally tall (I estimate most of them were only 6'') but there were a lot of them. It also seemed like the center of the pool and the N-rim were constantly sizzling a few inches in height. The pool was higher during this time than I have seen it recently, it was pushing out an impressive amount of water down the main channel and was even flowing a good amount of water into the second channel. We also saw what we thought was runoff coming down the "backside" (closest to the bw). The wind picked up and seemed to kill it around 1900. Entering a note because this was the hottest I have seen 'tess in a long time. |

Much increased activity from prev. days. High water level in Giantess' pool most of the day. Frequent boiling episodes, slowed down after the wind picked up but still put out semi frequent and relatively large activity despite the wind. Numerous 6"+ boils, several 1'+ boils, and a handful approaching 2'. Many with water pushing over the north or west rim. Near constant superheated boiling/bubbling across the pool. Boils are concentrated in the North/West quadrant, along the rim and towards the center of the pool, and are often doming, wide, or have multiple points.
Vault steadily rising most of the day, peaked and started dropping later in the afternoon. |

(wc) Had some decent activity this morning, but overall it declined. Whether that was weather-induced I don't know, but the two days before had good boiling activity despite unfavorable winds. Perhaps Dome's playing a role in it, too, as its series started somewhere overnight. |

(wc) Good activity throughout the day. Multiple decent and sustained large boiling episodes seen, though the majority were bubble showers. Episodes happened during strong winds as well. North semicircle was focus of activity, nothing seen from southeast rim. |

Vault up to more normal level after being low yesterday. Lot of bubbles in the back of the pool.
GTS's pool higher than yesterday, at or just below the sharp edge. Near constant simmering noise with boilups. One 1'-1.5' boil at 1034 that put some runoff on the NE side of the pool near the channel. Wind started increasing around 1047 and the activity has slowed considerably. |

Saw and heard an explosive boil 3-6 feet high while at Aurum. Went over to the Giantess bench to investigate and have been observing since Aurum. North rim boils are frequent and wide, but not very high and not putting out a lot of overflow. Between concentrated boils the entire pool is in a simmering boil. Vault is only 2 inches below the rim and bubbling on the South en. Giabntess's Pool level is very high. The North Runoff channel is wet to the base of the Mound. Will continue observations until hunger takes hold or activity decreases. |

(wc) Picture-perfect steam devil formed over Giantess, easily over 75-100 feet high (based on height measurements done in-basin during Giantess' eruption). Steam column started rotating @ 1824:34 and became very distinct from the rest of the steam 21 seconds later. Attained maximum height @ 1825:01, after which it rose upwards. Started dissipating @ 1825:12 and was gone @ 1825:22. |

Some increase in activity, and a better overall status quo than the previous week, multiple larger boiling episodes this morning put out increased levels of water. As well, Giantess also had overall more boiling episodes, and longer periods of forced steam during the morning when the wind was calm. However, after the wind picked up in the afternoon both the boiling and forced steam episodes were minimal. |

Pool level at the sharp rim at my arrival. The slope behind teakettle had a very small trickle on it. Had a handful of boiling episodes, the largest reached maybe 1.5' and put out a fair amount of water over the north rim. A couple others that put out a little water over the N. rim. Wind started picking up around 1200. Giantess calmed down and the pool dropped a little bit. Vault still right around the water level of right before the 9-10 GTS. Still has bubbles breaking the surface in the back. Infant seems a bit lower than yesterday. |

Large boiling on Giantess at this time, due to steam the water could not be observed. However there was dramatically increased steam, and lots of forced steam at this time. The boil pushed out enough water to create a separate steam plume following the runoff down the channel. Runoff steam plume was not visible earlier in the morning. (Even when it was colder) |
