Jens Day said Steamboat was very active from 1000 to 1300. At about 1300 it made a very strong attempt to erupt and then quieted down after that. |

Snow coach driver refused to allow us to go in basin despite pulling into Norris parking lot. From Norris parking lot, large steam column visible above fog but no audible sound. Entire valley heavily fogged in due to eruption so no view from overlook either. |

Little to no overflow. Runoff channel filled with snow from the "dead forest" all the way to the bridge. North vent having some considerable angled minors. South vent having small angled minors and MAYBE one brief vertical splash. Overall. It looks worse than when I saw it a couple weeks ago. |

Weak concerted activity from both vents with 2 vertical splashes seem from south vent and some bigger angled concerted play near the very end. No north vertical seen. Steady 1 runoff on the steerage scale. Trough is mostly filled with gravel and there are gravel bars near the vent and in the channel as viewed from lower deck which suggests no big minors yet. Trees continue to he killed further into the forest. |

Another large spike similar to a major eruption event, and similar to the events of 12 and 24hrs prior. This is put here in the context of reports (I do not have specific references at this moment) that SB had periods of exceptionally large minor eruptions in the 1980s and 1960s without erupting that dragged out its intervals as it regressed into dormancy. I leave these notes here in that (possible) context. |

Water probably returned somewhere in this range. Steamboat has been enjoying making ice dams on the logger probe. Water was definiftely back by 00:30 on 12/25 but could have been as early as 0300 12/24 with the initial trickles forming an ice dam on the probe.

In my brief time there with the Frolic Tour, I saw plenty of average sized angled minors, most non-concerted although there was one concerted minor that resulted in a few vertical shots from north that never got very high. And then south sustained vertical, again, with little height, a little later. I wasn't very impressed for day 7, based on my limited experience. |

Water possibly returned back to steaboat during this time. Its been making ice dams on the logger probes. This one formed around 12:00 on 12/13 and melted from overflow on 12/14 around 12:00.

Pathetically poor pushes, hardly any runoff, none in SV's back channel. Due to wind direction we could not tell if the few concerted minors had anything resembling vertical. SV splash zone above the steam vent (the one that sloshes water during eruptions) was still snow covered until ~1530. |

Not much from Steamboat. Most of the splashing was North vent and was angled. Weak run off all day. No Woo-hoo moments. Judging from the run off by the bridge and the snow/ice on the sides the Micah score was usually 1, some but not much 2, and maybe one weak 3. Maybe tomorrow. |

Did not see a steam plume from elk park driving in - geyser fog must have been thicker than it looked. Plume looked a little larger than normal from PL, didn't figure out it was IE until I rolled down my window. Left the car at 0434. In front of platform at 0437, to Steamboat in strong steam phase. Decent flow down both NV and SV channel still. LOTS of debris on the steerage bridge, stretching longer than the railing and including several fist sized rocks! Everything SB was raining on was freezing over. BW's extremely slick. Winter wonderland of frozen trees around the upper deck and dead tree zone after sunrise. 0520 NV started sounding more sputtery and started gaining a lot more water content. SV steam started to die down. It got really wispy and started looking like it might eventually just drop out. 0530 wind shifted and SB resumed steamphase. Bummer - we were getting curious to see where that was going to go. C&B left and a little but after that the wind shifted and we started getting restarts. The restarts were not very tall (the highest ones probably topped out at around 50'-60') and the pauses were short. NV would pause, SV would go to roaring steam and die down almost all the way, then NV and SV would pick up at close to the same time. No SV double-clutching observed this time, and the water never turned dirty. Pauses noted at 0640, 42, 45, 48, & 50. Partial/near restarts noted at 0655, 56, 0703, 05, 10, & 13, where NV would start to die down, SV would go to roaring steam, and NV would start to pause, but not quite stop before taking off again. More full restarts at 0715, & 18. More partial restarts at 0723, & 24. 0805 full restart. 0806, 07, 11, 12 partial restarts. At 0812, & 14, there were a kind of cross between the partial and full restarts where NV would stop but only for a split second before restarting, not giving SV a chance to die down. Wind changed again after that and the restart action was over. Steamphase roar still quietly audible from the parking lot. Eventually it started to sound sputtery again. Possible restart events noted from the parking lot at 0859, 0903 and probably a few other times as well. |

Thanks for not waking us up, and thanks for another great year. Have a great winter and hope to see you in the spring! Bye for now buddy. 0520 NV getting some water back and sv to light steam. 0530 wind change and one last shower for the road.

Kind of lousy play. Based on reports of activity around 1800, thought we would get something around 2100ish. Never came. Decided to cut it at midnight. Sure enough, a minor convinced me to stay an extra 10 minutes. An active period started at 0004 which contained bounce at 0010, and a Woo at 0029. That's it. Left at 0130. |

Steady trickle down South Vent Runoff Channel. One minor at 13:05 that was sustained for about 15 seconds, north and south both angled to 20-30ft with very very small amounts of vertical (ET briefly gone by both vents) with a babbling brook down the SVRC. All other minors weren’t worth noting. North routinely was angled to 20-30ft. South sometimes showed itself. NOTE: Ice in the trough at base of SVRC. Logger is probably still iced over despite runoff. |

Saw two decent minors. One at 17:10 was concerted and vertical from both vents. Runoff at Steerage was a 3. One at 18:54 got all of us standing with a solid pi (3.14159...) on the runoff scale (Udo and I debated 3 or 4). The minor itself was large, with North at 40-50ft, South at 30-40ft and thick columns. Neither minors had any real follow ups.
The rest of the period was basically garbage. Nice steady runoff at Steerage but nothing to really write home about.
Norris closed at 19:15 for construction. Theoretically it’s only for two days. Fingers crossed that SB false starts itself through construction. |

Arrived to poor looking activity, which turned suddenly to a small active period from 1150-1250 with a few brief NV verticals inside angled minors. Woo-Hoo at 1407, with a few slightly smaller vertical minors to follow it up. Down at steerage, had minors at 1740, 46, & 50 that produced at least a level 4 runoff, with the one at 1746 probably reaching a level 5. That one looked to be at least a Woo-Hoo from steerage. Runoff between active periods dropped pretty low, but energy seemed to recover pretty quickly after the end of each active period. Active periods also seemed to be pretty well defined throughout the day. |

Not much interesting happened today. No minors that were worthy of noting in my book. Just very random splashy activity. Some consistent runoff at steerage but it never made it above a 3 on the runoff scale. Cistern Spring on the other hand was interesting! VIGOROUSLY boiling and blooping to - 6" in 2 places. The boil is sending out large waves which by late afternoon dropped the pool level so that overflow was only only in the 3 established runoff channels and being push out the stong waves |

At 1530 there is evidence of a solid 4 runoff at steerage. I didn't see much concerted play during this observation. 2 SV solo's ~15' during this time period. NV ~25 '. |

0800 - 0900 Not much notable activity. At steerage just a consistent trickle of water till about 0904 when we had a concerted minor that put a weak 3 down the channel with several more after that until I left the area. Cistern pool is high with a good boil and in overflow. |

Improvement as the day went on. Sustained concerted minors at 1343, 1347 (with Sj to 20’), 1357 (both S & N to 20’), 1419 (N & S both near treetop level from lower platform - no NV), 1425, 1535, 1540, & 1718. After I joined Bob at about 1640, concerted minors with NV were seen at 1659 & 1700, plus a quick NV bounce at 1719. Some of the minors seen today produced Babbling Brooks. |

The best minors that I saw were at about 1245 - 1255. One included North Vertical ~10-15’ and sustained for a few seconds. At 1250 a concerted minor had a rumbly shake to it. Some of the minors had quick pauses inserted in them which I think will probably turn into longer sustained minors as we get go further into the interval. |

3D 20H PE. water has returned to the system. SV ~15', NV wispy angled jets ~20'. Not much grumbling. Back shoulder is dry. SV had one meh solo, angled jet that put a fair amount of water down the channel. SV channel is wet with a consistent flow of water into the trough and out beyond the bridge to the creek. 1756 Concerted minor that put a 2 on the Tara scale down SV channel. Cistern Spring is high. Overflowing in 4 directions including the muddy pool. sorry for no morning report, we went on a hike. |

2D 12.5H post eruptive. SB is quiet and gently steaming. Water has not yet returned to the platform. All runoff channels are dry as is ET and Jabba. Cistern Spring is in overflow in all 3 directions. (not into the muddy pool)and all its overflow catch basins are full, steamy and overflowing. The pool is milky and a brilliant blue color. Nice boil. |

I noted that the South Vent channel appeared to be very white by 0957. Some things looked better today (better organization of some minor series - build-up & follow-through). I noted Raging Rivers at 0953, 1059, & 1143. The big change, though, came at around 1730 with a very strong series that was more typical of those before previous eruptions. (On days before this, series often consisted of one strong minor followed either by weaker ones or with no follow up. Those usually had no buildup to the strong one. Also, the stronger minors usually ended with a South Jet solo.) |

Sustained minor, seemed to be more of what was reported earlier with NV & SV vertical but SV took over the minor, holding at 30' with heavy discharge, then all quiet. No follow up vertical, left platform at 2240. |

Some strong, mildly bouncy minors throughout the day. Almost all minors accompanied by strong output from SV which seemed to take over most of the energy. NV wasn't able to sustain any of its minors to make that final push. |

Spike reaching 59.5°C/139.1°F at its highest @ 2322:38 E occurred between these times, with @ 2318:38 E 41.9°C/~107.2°F (spike ~start) and @ 2330:38 E 41.2°C/~106.2°F (spike ~end). Probably a 'silver bullet' at that time or a set of closely-spaced minors. Rough average between 2200:38 E and 0100:38 E was 35°C/95°F, excluding the spike. |

Evidence of good overflows overnight. During observation period overflows stayed mostly at a 2 except for the following: 1031-3, 1040-4, 1056-3, 1109-4+ (NV tall vertical SV sustain), 1115-3+, 1124-4, 1209-3, 1236-3 (NV low vertical), 1240-3, 1301-3, 1307-3, 1314-3. 1109 minor was the strongest seen, "Woo" on the platform scale but did not get called on the radio and no immediate follow up. No radio calls as of 1400. |

Almost all minors had concerted starts. The best minors were at 1309 (~a 20 second duration), 1337 (C with some North Vertical but not too tall & BB that I could hear all the way down the channel), & 1351 (C with quick N bounce then N Vert & BB). Some jetting from South Vent, (over ET), and a couple of small bounces in the North Vent center spot. |

4D 5H post eruptive. Steamboat is spashy and rumbling. very steamy and cold this morning, hard to see the vents activity other than steam. Some streamers from NV ~25+'. SV ~15+' based on streamers. SV runoff channel has a fairly constant runoff as does the back shoulder. The trough has additional gravel added from good minors and stick is 13" exposed. Cistern Spring is clear, high, overflowing nicely with a nice 2 point boil. |

2D 6H post eruptive. Gently billowing steam. No water, light grumbling, runoff channels are dry as is ET and gabba. NV runoff channel just below the bridge is still steamy along the E berm. Cistern Spring is in overflow on 3 sides with what seems like a gentle boil. To steamy to really see but i cant hear it. Just see small convection waves. |

SB vents are still rhythmically huffing. NV is a mix of water and steam to 15'. SV all steam. SV runoff channel is damp as is the back shoulder. Cistern Spring is down 2.5' from the inner tube rim, calm and deep blue in color. |
