I observed Steamboat from 0730 until 1730. I concur with the notes posted by Micah and JeffL. The wind direction and heavy steam from Steamboat made it impossible to view the vents from steerage today except for early in the morning. Visibility was also not great from the main platform, so most of my observation from noon on was from the upper platform. North and South vents continued to progress and have voluminous and sustained eruptions at times. South was hard to see, but it had a fair amount of vertical splashing when it was visible. North had some vertical, but not much. I saw what looked like "granding" two times, though neither time was very tall. I didn't see any concerted sustained vertical minors . . . though it is possible they occurred and I just couldn't see them. I checked steerage a number of times throughout the day. Runoff was significant at times and the trough at the bridge continues to dredge slowly. The runoff channel has also changed quite a bit, so measurements using middle rock may not be quite as useful as in the past (sorry Micah) to gauge the amount of water coming down. I'm surprised at how quickly the activity is progressing considering how dismal it looked on Friday. |

Good flow out in runoff. Steerage only has some dirt. Had some very good minors out of both vents. NV went near vertical a couple of times. SV had a good amount of water coming out of it. Hard to see if SV was going vertical just due to the amount of steam both vents were putting out. |

I observed Steamboat from 0800 to approximately 1230. Most of that time was spent down at Steerage logging runoff but the last half hour (during which time no detailed notes were taken) was spent on the Lower Platform watching minors. In short, activity has continued to progress since last evening. South Vent is strong, with frequent voluminous minors that occasionally get vertical and send nice discharge down the runoff channel. North Vent is also more active but not to the same extent, voluminous but staying mostly angled. Concerted eruptions were more frequent this morning but still not as frequent as we should probably like. At 0836 there was a Woo-hoo minor that sent a nice surge down the runoff channel. 45 minutes later at 0917 there was a solid OMG! that sent RMichaels and I jumping to our feet with exclamations, there was brief, but solid granding in North and South Vent was doing it's best Fan impression. Those were the two strongest minors seen. Throughout the rest of my time there was a peppering of decent, but brief minors with some vertical play and heavy runoff. The trench is slowly being dredged, with some change from last night, specifically an absence of finer sediment, with most clasts being pea-softball sized. It will take some more strong minors to clear everything out. |

I observed Steamboat from around 1840 to 2015
.
I spent an hour from 1840-1940 at Steerage logging runoff over middle rock and observing the trench. The trench is filling rapidly with gravel. Each wave of runoff, even small ones, are sending gravel into the trough. "Elvis" rock is undercut by several inches now. The runoff channel has been scarred and heavily altered since the winter with large patches missing and new large rocks and debris.
As for the minors themselves. What I saw seemed to be an improvement of the observations by Jeff L. There is some nice strong South and North action. With both throwing some vertical shots in occasionally during stronger concerted minors. There were several heavy concerted (but NOT vertical) minors that put water about halfway up Middle rock (2.5-3 on my runoff scale).
After I finished my hour of detailed observations. I headed up to the Lower Platform where I observed three consecutive strong concerted minors (2003, 2007, and 2010) that put a flood of water with visible rocks roughly the size of tennis balls down the channel. It looked like it would have covered middle rock. The first minor in that cluster started out with some vertical shots but did not sustain, and the two following were weaker and shorter, but still had decent volume. |

Had a few nice minors out of both vents. Nothing vertical or concerted. Steerage is still dirty but the runoff is pretty wet and starting to clear out some of the dirt and gravel. Some nice bellows coming from the vents as well. A lot of play out of SV, but not so much out of NV. |

Boardwalk to Steamboat is open. Steamboat very quiet. Only occasional splashing from either vent. South Vent runoff channel completely dry. Cistern in light overflow with one boil in center. Suspect there may be ongoing disturbance affecting at least the back basin because two features near Orby were having muddy eruptions. Porkchop also had no water in it. I didn't do a full tour of the back basin but it appeared from a casual glance that many typically quiet features were erupting or had more water than usual. I spaced out looking at Emerald to see if it was cloudy/boiling. I believe others made more detailed observations. |

In steam phase. No water seen. Quiet enough that you didn’t hear it until almost to the platforms. The upper platform had about a 1/2 inch of ice. The lower platform was covered in enough ice to support 7 people without breaking. It thinned out as you went down the trail to Cistern, but then it broke up and I didn’t care to post hole my way to see where Cistern’s water level was. |

Light splashes seen, and inferred by steam seen later in Back Basin, but nothing is clearing the immediate vent areas. Snow in both runoff channels - trough full of sands and gravels, ...and slushy water. Cistern in good overflow, muddy pool full and surrounded by white snow. |

Fickle B. went while I was en route. Saw the column from Gibbon meadows @ 828. Screw it - I'm counting it as water. (Also saw some spikes from Elk Park, the parking rink, and Emerald.) So 12 this year: 1 steam, 1 water/steam, 10 water, 8 from start. No runoff seen anywhere other than E. and W. main channels. Still in steam at 1400. No weirdness up to that time. So much ice on the car cover that I've got it thawing in the tub. The larger (6-12') trees N. of SB were so ice laden when I left, they were bent over 90 degrees. |

I stopped for one more look, mostly in the dark. I heard 4 good minors, they appeared to start with the north vent tall and not quite vertical. South joined in 5-10 seconds later 10-20+ feet with loud run off. Part of me still thinks I was a fool to leave, but the wise words of Bill Warnock gave me strength to get some sleep and come back in the morning. |

Saw a chipmunk and two ravens.
N. Vent seems ready to go. Tall, sustained and frequently vertical. S. Vent seems to be lagging [seldom vertical, poor runoff from good minors] but improved during the day. When S. Vent did chime in, it usually resulted in Whoo-hoo or H-S level minors; some w/ good runoff, some without, but seldom back-to-back and usually brief. Trough dredged. Overall, slightly ahead of where I thought it would be. BWTFDIK? |

Morning 6 minute stop had one solo angled NV about 30' followed by a fairly beefy SV to 10', then again with North not as tall. I thought they were alternating a bit until I saw single skinny NV jets with no S. Later concerted action was 30' North and 10' South. At 945 the trough was full of sands and gravels. At my 1700 walk by the trough looked a little cleaner - away from the wall about 1.5 inches, but still quite full. Some of the finer materials were washed away from the wall leaving only the gravels, but it's still heavy sand near the bridge. While I watched several red bb's and red peas came bounding downhill to join their buddies in the trough - so that could explain the larger materials being there. Didn't stop at the platform on the way out but did see a 20' NV and not much from S. Cistern had a gentle boil, hard to see in the a.m., but I wouldn't even call it moderate. |

Gentle puffs of steam. We could not see any water in Cistern. I would say it was fully drainer. I don't know how to edit my observation of the eruption but after reconsidering I would say the water phase was more like 45 minutes, not an hour. I still see that giant wall of water every time I close my eyes! |

Both vents jetting constant water from 0930 through 1200. N, from 15-80', S. from 10-40'. At no time did either vent pause. Just before noon there was a phase shift. Both vents went to ~50% steam, and water height diminished. By 1230 both vents were ~75% steam. By 1330 mostly steam with a water component to 3-12' from both vents. I'd guess Cistern was 4-5' from empty when I left (water at bottom of SE alcove). |

No Steamboat eruption as of 1855. This afternoon we had more vertical from North Vent . South Vent was much stronger this afternoon. There were several woohoos with the ones at 1517 and 1623 showing great promise. From 1215 to 1220, I heard a new sound from Steamboat. It sounded like "thrumming" or a low toned rumble sound like a rumble strip, but definitely from Steamboat. |

No Steamboat eruption yet. We had a couple Concerted with vertical between 1200 and 1300 followed by a lengthy quiet time with little activity. Trough is partially dredged due to babbling Brooks with 3 raging rivers. Cistern is full and overflowing with a boil that varied from little to most of the pool. Emerald is clear and overflowing. |

Said to look better than yesterday. Some vertical elements in S, Vent early. First meek vertical in N. about 1245. Good minor push from 1300-1330 with a couple of Whoo-hoos. That took the trough from being about 1/4 dredged to 1/2 dredged. Nothing of note until a sustained but weak vertical minor about 1500, followed by some Billing 10 min. later. Then nothing before I left. Trough still 1/2 dredged at 1600. Cistern was witnessed several times to have wide area of boiling (3 vent) to 4-6" which disturbed nearly the entire pool. And was once reported to be boiling but from a fairly calm pool. More bubblers have reactivated in the W. runoff channel below the middle obs. deck. Eventually putting water all the way to the bridge. |

After seeing that steamboat went off this morning went to go check it out for the last time this year. I leave Yellowstone in a few days it's been a fun summer. Getting to see steamboat was the highlight while working at the Canyon Lodge Gift shop. When me and Jon arrived NV was is a mixed water/steam phase and SV was all steam and stayed that way until we left. Cistern spring was down about 6-10". Some water coming down the NV channel. It was fun to meet and talk with all the geyser gazers this year. |

One strong vertical minor from North Vent to the height of the trees at 16:37 that produced noisy babbling brook runoff, but it was not sustained. Following 15 minutes had decent minors with 1 follow up vertical from North Vent at 16:50, not as strong. Activity decreased afterwards. Small vertical surges from North Vent as I was leaving at 17:18 (sucker surges?). It was the best period of activity I had seen all day. Hopefully bodes well for tomorrow (and not in the dark overnight). |

Meh. Poor visibility. Improved during the day. Similar to last Sunday, but with more from N. (mostly angled) and seemingly less from S. Trough was mostly dredged after a decent minor around 930. Had accumulated more debris by 1600. At best 2 Micah 5's during observation period. With maybe 2 more 4micahs. Some decent minors with poor runoff. Suzanne called (thank you Suzanne) a minor with good N. vertical as I was driving past Elk Park. So, at least it has learned a new trick to go along with the only other trick it knew (good concerted vertical minor with good runoff whenever anyone packed up to leave). Yay? |

Majority of North and South Vent minors were angled and not large. Trench was only partially dredged. Small vertical minors seen from North Vent at 846, 907, 927, and 929. 927 was weak, 929 was sustained. They produced babbling brook runoff. |

Audible shift in steam phase may be the beginning of a shift to mixed phase. Repeated at 1523. Longer sputtering (motorboating?) started at 1547 and again about 1557. More water appears to be entering steam plume with each change. Also raining heavier in whichever direction wind is blowing. Sounds like a higher pitched sputtering (motorboating?) than the low rumble. These shifts also displayed a rooster tail of water centered in the steam that grew in size with each one. Had to leave around 1600 but my guess is the mixed phase was still hours away by then. |

ranger laura reported steamboat re-entering pure steam phase around 1330. I arrived at 1350 for my last steamboat talk of the season and as soon as I began talking, it re-entered a strong water phase with over 100 ft. from the north vent and continuous water from the south vent. I left at 1515 and it was still going strong, no run off though. more later. cistern may have paused its drain. |

At 9 AM, was in pretty mild steam phase, geyser icicles in the trees. I returned at 10:00 AM after hearing sound increasing from the museum area, and the north vent was blasting water (with some mud) with max heights of at least 150 ft. with fluctuating powerful steam out of the south vent. It was similar to the crazy fluctuating bursts during the water phase of the last eruption. This continued for at least half an hour. Upon returning at 11:30, the north vent was in steady continuous water above 100 ft. with mild steam from the south vent. Quite a show. "Steam phase" seems to be a misnomer. Will continue to monitor as much as possible. |

Increasingly strong minors and audible rumbling building to multiple concerted minors with tall vertical play from North Vent and heavy discharge from South that moved a lot of gravel in the trough. NV vertical at 1323 (woo), 1327 and 1332 (woohoo). |

Slow but mostly steady improvement throughout the day. 1625-1634 had a nice series of minors that had 2 short vertical North Vent bursts. By the time I left North Vent had picked up more volume & height than it had earlier in the day. Also, rumbles seemed to be a bit louder. |

Water is returning to the platform. SV runoff has a thin area of dampness just below the vent but water has not reached the bridge. NV had a few 5 - 10' splashes one at 1128 that was CNV with a 3' V splash. Cistern Spring is overflowing with a 3' diameter boil and is a milky blue color. No water at the bridge. Emerald Spring is clear, calm and a beautiful turquoise blue color with patches of green on the rocks within the pool. |

At 909 steamboat had a pause, the steam dropped and then restarted with water from the north vent for a few minutes. At 1124 water started coming out of north vent again to about tree line. It also had a brief pause during this and shot up some rocks as well. Around 1130 went back to mix water and steam from North vent. Cistern spring was a few inches from the top when I got there and when I left it had drained about 12-14". |

Heard calls of 3 consecutive big minors as we drove into parking lot. Reported that trough filled this afternoon and was mostly clear when I went down to bridge. Observed several strong concerted, vertical minors, nothing sustained for more than a few seconds. Cistern was still overflowing heavily, apparently unaffected by the strong minors, which has been the case in past 2 eruptions. |

Spent an hour down at steerage. There is still a lot of silt in the trench but it is partially dredged. On a Micah 1-10 scale overflow averaged about 1.5. Minors are occurring but not very voluminous. North and South did throw in some vertical splashes several times during concerteds but nothing that got me excited. |
