Runoff completely clear. Frequent concerted minors to tree height with at least 3 considerable vertical minors sustained for 10-15 seconds each putting down a nice (but not massive) wave of runoff. A coworker of mine who came around ~0800 and has been at the upper platform since told me there has been a large increase in the size and volume of minor eruptions since then. |

Light steaming with some weak huffs. The channel is mostly clear of snow but some higher projections have patches which indicate that it's not having significant minors yet. If anything. |

nothing too impressive during a short sunset visit to the frozen deck of steamboat. runoff channel still quite snowy and frozen on the edges, so i dont think they has much significant flow. notably, cistern is low, a few centimeters below the scalloped edges. I'm no cb or bbev but there's my best in-basin update. my fingers are still thawing out. |

Forceful steaming from both vent as we wave goodbye.
Water running down far back channel, possibly from condensation from W wind. So long you FB, hope to see you next spring :( Evidence of lots of runoff on Echinus side of steerage and would guess a shorter duration. Cistern down 3', just to rim of inner tube. |

5D22H PE. Steamboat had some nice concerted minors this afternoon with good runoff and verticality. :) A really nice, thick, tall, concerted NV with SV fountaining that produced a raging river down the channel. Interesting! Cistern Spring Pool has dropped a little. Water is lapping at just below the scalloped edges of the pool. Overflowing out the established runoff channel to the south and a bit out the backside. Runoff channel toward Veteran is trickling into the catch basin but not any further. |

13H 15M into the eruption. Both vents are still throwing water! NV 25' continuously. SV 10' with a steady stream of water flowing down the runoff channel. Cistern Spring is down ~1.5' below the inner tube rim. It is calm, steamy and blue!
@ 1149 both vents are still throwing water! NV 35', SV 10+ and both continually. Cistern Spring is down 2' from rim of inner tube.
@1251 SB had transitioned to billowy steam as viewed from Yellow Funnel and Orby.
@1551 SB (19H into eruption)is rhythmically huffing billowy steam. Interestingly, SB's platform is dry and it looks like it's been coated in a layer of dried pottery clay. Especially Jabba. SV runoff channel looks like it's been painted with plaster of paris or a Porcelain paint! SO white! 19H - Cistern Spring is empty of all visable water. |

2 nice minors that could have lead to an eruption but NV just doesn't have the juice/umph/upsie to push through a good vertical minor to take it all the way to eruption. One at 1133 that put a solid 4.5 (5 is eruption)down the runoff at the footbridge and had many up on their feet shouting! Another at 1418 that could have been a start but just didn't have what it needed! Both had tall vertical SV that put a raging river down its runoff channel. Cistern Spring is still VERY low and overflowing only out of the established channel to the south. The scalloped edges and biscuits are WAY exposed. (1.5") Very chilly and windy day. |

Activity picked up at 1630 with tall vertical NV and good SV runoff. 1745 nice CNVVSVH++ and another around 1830 as I was getting ready to leave. Cistern Spring water level is very low.

NV seemed to dominate the day with nothing but angled jetting. No vertical play except for a very slight spray around 1700ish. SV was hard to view from any angle for most of the day due to the cold, snowy, steamy conditions that blew SB steam toward the platforms and down toward the foot bridge. SV play & runoff picked up around 1530 with some better runoff and loud percussive grumbling. NV continued its nearly constant play till I left at 1930. |

You know the Fan and Mortar notes “angle never quit”?
North essentially didn’t stop for several hours. Nearly perpetual angled jetting that alternated between wispy and heavy. Pauses occasionally. One seasoned observer likened it to “wild phase” activity just bleeding energy off the system all day. Absolutely NO signs of a disturbance. |

No Steamboat as off 1600. Weather started deteriorating around 1500 switching from rain to sleet to snow with steam from the geyser heading either toward the main platform or toward the bridge. Viability was poor most of the afternoon. Saw continuous line of vehicles from Madison intersection to Fountain Flats due to a small herd near the road plus one lone bison in the canyon. |

Steamboat continued its activity over night. At 0047 and 0048 a large minor event got Ben and I’d attention. NV was vertical and sustained around 40’ with SV dumping enough water to move most gravel out of the runoff. This event repeated at 0114. Somewhere around 0420 while Hope Brooks and I were surveying baselines at Decker Island and Decker 2 another minor put enough water to cover the grassy knoll. At 0400 the wind shifted and I moved from the Upper platform to Steerage to avoid being clobbered by a surprise eruption. Runoff was a steady babbling brook from 0430 to around 0615 at which time it began slowly dropping to a trickle.
The behavior pattern where SV would build in size and volume over the span of an hour, ending in a large concerted minor eruption (usually angled but sometimes vertical) happened four times with the ending minors happening at 0048, 0213, 0330, and 0430. By 0700 this pattern seemed largely gone. It was very easily noticeable from the upper platform by watching the steam in SVs runoff gradually increase in volume and length towards steerage.
On a tangential note: the night sit was wonderful, warm and dry. The moon lit everything up, and some passing meteor shower produced large and slow fireballs once every ten to twenty minutes. |

At 0800 runoff at Steerage was barely a trickle and the runoff only went a few yards past the bridge. By 0900 the runoff had widened considerably and around 1100 there was finally a minor which fully wet the runoff channels and moved debris. NV rapidly began producing large minors with semi-frequent thick and vertical minors - but SV was no where to be found. SV slowly began increasing in volume throughout the day. A cycle developed where NV appeared to be in control, dragging SV along with it. This cycle ended abruptly around 1900 when SV apparently decided it was ready to play and there were three consecutive minors where SV was fountaining up to 35’ and North had repeated vertical surges. Ben and I moved to Decker after this to be in position to measure the starting surge just in case. For the next five hours minors were well defined and promising enough that we stayed well after dark. The cycle of NV pulling along SV ended after the minors of 1900 and it appeared SV was in control and dragging along NV with it in a cycle that progressed in definition over the next several hours. Minors that appeared capable of initiating an erupting occurred around 1900, 20:35, and 23:00. None had any follow ups.

3D22h40M. PE. SV runoff is damp 30' down the channel from the vent. DAMP is the key word here. SV channel at the foot bridge is DRY! Back shoulder is dry as is the back channel, ET & Jabba. Some occasional minor splashing out of both vents. SV 5' wispy splash. NV Angled 10' - 15' wispy jet. Sounds very "airy" much like this time last interval. Cistern Spring is overflowing on all sides with a weak (flooded) boil. |

5D2H15m PE. Steamboat has improved a bit from this morning. SV runoff channel has water flowing to the footbridge. The debris has moved ~10' down from the vent and is in small groupings directly across from the middle platform. Not enough strong minors to push them down to the trough yet. SV had a few 5' splashes and NV had some angled 25' jets, some that were "airy" and others that had more water in them but all in all the platform was not very impressive tonight. See what tomorrow brings! |

1D18H PE. STEAMBOAT is gently steaming. Platform is dry. Cistern Spring is on the rise. water level is not visable yet, (~9' below the rim of the inner tube.) It is very steamy and has an audible roiling, vigorous boil that is putting up an impressive steam cloud. |

NO Steamboat yet as of this time. Many isolated strong minors throughout the day, many folks left at 2030 as a storm moved into the Norris area. |

SB platform is still dry as a bone! Some very weak angled play from both vents. SV - 5', NV - 8'. No water in SV runoff channel at all. Cistern Spring is in overflow with a mediocre boil. 1815 walked by again and SV has 5' thin trail of water/dampness that is just starting to extend down from the vent. Back Shoulder, back channel, Jabba all bone dry. |

5D5H PE. Water levels improved exponentially overnight and we had some nice minors with good runoff throughout the day. One minor that started just as a thunderstorm was passing us and it got many of us up on our feet coaching it to start but alas, it did not. Good minors after that but "no Steamboat yet". |

SB is just starting to get water into the platform. Only 1 CNVSV minor that had a small amount of water discharged @ 1024. SV runoff channel is damp ~30' down the channel as viewed from the middle deck. SV channel is bone dry at the foot bridge looking up the channel toward the vents. Back shoulder and back channels are bone dry. @ 1330 SV water had still not reached the foot bridge. @1712 SV runoff channel has a THIN trickle of water at foot bridge. At middle deck some CNVSV minors that put a wee bit of water down the channel but not enough to move the small rocks and debris at all. Back shoulder has a few thin, damp areas but not much and zero water in the back channel. **FYI the Norris basin, parking lot and road will be closed at 1800 tonight thru ~1000 tomorrow morning to move new exhibits into the museum. Please be considerate of this closure! |

16h PE: Steadily billowing fluffy steam with occasional weak puffs out of NV. Some water still pooled in the runoff as viewed from middle deck. Cistern is 1.5-2' below the inner tube, with a bright blue color. Wind direction caused the area of boardwalk between Cistern and the bench before Steerage to be coated with .25" of pine needles and dirt. Muddy pool is particularly full with water. |

Activity seems largely the same as yesterday so far. A single nice minor at ~11:30, and seemed to perk up a bit afterward, some good grumbles and pops. Had to head out hope it lights up for y’all! |

Steamboat was really lackluster this afternoon. SV had not moved the small piles of pepples down the SV channel that were from the previous eruption. Play from both vents improved around 1600. Taller more sustained jetting from both vents, a few were vertical, that produced some babbling brooks. Cistern Spring has a VIGOROUS boil and overflowing on all sides. |

Overall a quiet day at Steamboat. The quiet overflow previously reported was the rule of the day, with some activity picking up around 1400 and about every two hours after that. Between 1600 and 1700 there were some minors that started to move a little of the gravel at the top of the runoff channel, but even that remained when the Hoppes left around 2000. Best activity of the day to that point was the last hour, but vertical activity was essentially non existent today. |

7H Into the eruption. SB is in mixed water steam phase. NV mix of steam and water 40' continuously. SV is huffing tall billows of steam also continuously. SV runoff channel is wet with lots of pooling water in low depressions and a thin trickle of water all the way down the main channel to the foot bridge. Cistern Spring's pool has dropped ~2.5' below overflow. Pool is clear and mostly calm with the exception of 1 point of small ping pong ball sized bubbles that occasionally break the surface. |

SB water levels have improved somewhat from this morning. There is a thin river of constant water at the foot bridge and water in the main channels extending into the delta beyond the bridge. Play is mostly all angled minors from both vents. Some concerted play. Some SV fountaining. NV ~35' - SV ~20'. 1901 stronger CNVSV with a weak babbling brook. 1920 NVV bounce. 1940 NVV bounce. Some better CNVSV from both vents in the 1920 - 2030 hour that was taller and thicker with bounce. |
