2" of snow and NE wind made viewing difficult. Plenty of concerted play with strong SV and heavy runoff. NV tall and thicck, 40-50'. First vertical splash actually seen was at 0900. IMO NV seemed slightly more active than SV, although SV had numerous vertical minors, whereas NV merely splashed 3-5 ' in the vertical area. 0900 to 1200 strong concerted minors seen from upper deck, NV jetting 50-70', SV vertical 30+' two to three times an hour, but impossible to see if anything from NV approached vertical. Two NV vertical splashes seen at 1219 and 1226. NV continued jetting thicck minors to 50'+. 1330 to 1630, wind change allowed for several NV vertical splashes to be seen. Concerted play continued with SV 30+' and NV jetting to possibly to 60+'.
1655, increased activity. 1700, strong concerted with vertical NV, followed at 1705 by a sustained, concerted NV vertical. 1725 concerted with tall, thicck NV with vert. splash. 1735 Very long, sustained, vertical concerted minor, best of the day, that put a huge amount of water down SV channel, lasting about 20 seconds, followed by NV jetting 60+' but unable to see if vertical due to steam and wind direction. Next hour was relatively quiet followed by an hour of active concerted minors, some NV vertical splashing. Going home at 6 day mark, No eruption yet. |

Steamboat didn't have any exceptional minors during the times observed. By exceptional minors, I mean minors that would formerly be described using the highly subjective and now universally panned terms of "Woo," "Woohoo," "OMG," "Holy S___," etc.
Steamboat had periodic increases in activity every few hours, but very few minors with any North Vent vertical play. As Bill mentioned in his note, the wind made for difficult viewing conditions so it's possible vertical play was obscured. Despite the general absence of vertical, North Vent was thick, tall, and voluminous. South Vent produced good runoff and appeared to have frequent vertical play (from what could be seen through the steam). Each vent had good energy and there were quite a few concerted eruptions. That said, it seemed to me like the energy shifted back and forth between North and South vent and they only occasionally matched energy levels. As of my departure time, it looked like a regression in activity compared to yesterday, which had some tall sustained concerted minors with vertical play from both vents that got observers on their feet. One minor at 1156 yesterday even caused one observer to yell "Woo!" in elation and encouragement. No such exclamations occurred in my presence today. |

Good water levels in both vents for this time post eruption. (3d18h) Mostly concerted starts but SV occasionally dominates with very tall (granding*ish) play accompanied with good babbling brook+ runoff. NV angled jetting 20' - 35' and will stop when SV dominates the play. (37°) Cistern Spring was to steamy to see clearly but was obviously overflowing. |

41° Steamboat is gently steaming from both vents. Slight gurgling can be heard from the middle platform. SV runoff channel is dry. NV runoff channel still has some pooling in low areas and depressions. Cistern Spring is refilling and water level is 6'' below the rim of the inner tube. It has a 2 point vigorous boil. |

Arrived at steamboat 645. It is in the steam phase. Cistern is about 4 feet down from the top. Runoff Channals have small amounts of water in them milky in color.
All of the decks were total ice for about 1/8 of a mile from steamboat. Most of the ice had melted off by 0745.
Several notes from yesterday‘s eruption. I arrived at 1130. For most of the day it had runoff’s every 5 - 10 minutes (babbling brooks). I was at the decks for most of the day, I did do several walk around in the lower basin and up to the parking lot. During the day until eruption I did not witness any Wahoos or OMG’s.
At 1752 there were a series of Wahoos and OMG’s for approximately 2-3 minutes, Steamboat went dormant for a few seconds and the went into eruption at 1755. |

Lots of concerted play throughout the day with SV dominating the action. SV had continuous runoff with strong, vertical, sustained minors occurring once or twice an hour. Vertical NV minors were less frequent, and shut down by SV quickly. There were 2 events during the day where NV was sustained for maybe 5 sec. with follow up, impressive con....STEAMBOAT 1956! Radio call at about 1953 of 4-5 BIG minors as l am writing this note at the trailer. Eruption called as we flew into parking lot. Tall, tall, tall seen from Emerald over the trees. l would say tallest of the half dozen l have seen from this perspective. Dirty NV with lots of rocks thrown above the water column. NV turned to steam maybe 15 min in, and SV continued to throw water 20'+ for the time we remained, about 2045. l am sure eruption post will have that info.
I was saying that IMO there had been 2 good events that where considered "whoo who", or, concerted, vertical, sustained, tall minors, that get you on your feet. Both of those where followed by another significant, concerted minor within a minute or two. The last of these was recorded at 1454. We had left mid deck at 1915 after, what l had thought, was a relatively active period that had not produced much. |

After a few isolated larger minors in the early morning, there was a Woo at 0949 and a Woohoo with NV Granding at 1038. From 1148 to 1225 there was a push with good runoff and occasional NV vertical, but the vertical splashes did not exceed 10-15 feet and could not sustain or build. Seemed to be headed into a lull by 1330. |

From 0730 - 1200 the activity has been mostly ( 80%+)concerted NV/SV events. 3 events producing some NV vertical action with significant raging rivers down SV runoff channel! Activity to this point has progressed nicely. Cistern Spring is in overflow with a 2 point vigorous boil. The addition of the boulder against the bridge has changed the ability to dredge the trough of accumulated silt, sand, gravel and rocks. It is down to bedrock directly beneath the runoff channel but the debris is piled up in front of the boulder. @1800 the debris flow has changed direction and is flowing out to the south. 1200 - 2030 had 3 notable events. A woo..at 1444 and 2 WOOWHO'S @ 1725 & 1848. @ 2030 there has been an audible increase in SB grumblings and increased sustained concerted events with SV raging rivers. |

Quietly steaming with occasional barely audible huff. SV channel whiter than yesterday (drier?). Cistern is overflowing in all directions with normal (good!) roiling boil over the vent. Both channels trickling at bridge area. ET has some white striping and a white left hip that disappear after wafting steam wets those areas a bit! Weird. Soft rumbles heard after 1400. |

SB is quiet and steamy. Bubbler 15' directly in front of mid deck appears to be putting out a trickle of water down NV runoff. Bubbler 50' up NV channel also active. SV channel is white and completely dry. Cistern boiling, a little milky, and overflowing out west side, very little to the east. SV runoff still moist but no runoff past bridge. trough is partially filled with fines and small gravel. Large rock has partially dammed the runoff under bridge. Breakout in NV channel has no steam, unchanged.. |

Quietly steaming. SV runoff channel is white. Cistern is totally drained with barely any steam drifting out. Tiny trickles are flowing down both channels, however upper part of SV channel appears dry. Erosion is impressive as is the new boulder that hit the middle of the bridge. Emerald Spring and its neighbor are clear and in overflow. |

SB is gently steaming with an occasional huff. SV is a chalky white color and is dry but has a thin trickle of water flowing down at the bridge. Go figure! Cistern Spring has no visible water, no audible churning sounds and the faintest of steam. "IT" > the "Interesting Thing" in the NV runoff channel was eroded by Steamboats eruption yesterday and has no activity/steam. The trough has an accumulation of fine silt and sand built up in the runoff pool but there is some bedrock visable with coarser gravel closer to the bridge and in front of the new boulder. |

NV was straight up, not angled, most likely because of wind direction blowing toward decker's island. NV stayed in steam phase with a thin stream of water in the middle. Crazy vortex that swirled around this thin thin thin stream of water. Stayed that way most all day. At 1930 NV was starting to huff steam/and this thin stream of water. SV was hard to see, NV steam blocked it. Temps were cold and windy. @ 1930 Cistern Spring was 12 - 14" below the rim of the inner tube. |

@ 1050 SB is in constant steam phase. NV runoff is milky white. I'm not seeing the cycling from steam to water that I've seen in previous eruptions at this stage. @ 1630 SB is a bit quieter but still in steam phase. I saw no mixed water/steam phase today. There is a big bolder nudged up against the bridge at the trough. It was not there last night. Cistern Spring is down 18" from overflow @ 1135. down 2.5' @ 1500. down 3.5' - 4' @ 1625. |

I wanted to add a few things to the RL Jones eruption note. Runoff water was milky white. During the irruption the majority of the water was running down on the East side of canals. It actually washed a rather large rock into the trough. Of course there were water in each of the canals; however, there was knee high water after I crossed the trough bridge.
In my opinion leading up to this eruption (05/08/19) there were no Wahoos or OMG‘s.
My observations were - Consistent 10-40’ minors from the NV & SV every 5-10 minutes with babbling water. Consistent for 36 hours prior to the eruption.
Lastly I wanted to say thanks to all the Gazers for the information and encouragement.

My observations were almost identical to Carol's for both SB and Cistern. I was able to observe SV as the wind direction changed slightly. When NV hit 40 ft SV would be around 20 to 25 ft. Most minors were concerted. Never were any vertical. The larger minors (NV 40 ft) became more frequent after 1830 occurring about every 10 minutes each creating a loud strong rush of water in the main channel. I checked the rock at the bridge and they never went around the left side of the rock.
As for Cistern: At 1755 there was light overflow out of the back left corner and the front right and was the same at 2005. |

SB is having some play out of both vents. SV runoff channel has had some nice babbling brooks. @ 1654, put water almost proposing over middle rock. 1658 & 1702, 1704, nice babbling brook. NV angled jetting 30 - 40'. Hard to see SV at middle deck as steam/breeze out of the west. Cistern Spring is barely in overflow. scalloped edges on the rim are visable. Overflow areas on all side are just moist. The "Interesting Breakout Thing" in the NV run off channel south of the boardwalk is not steaming today. ( weather today is snowy and cold) Trough is clear of debris just beneath runoff, (bedrock)but gravel still piled up in front of the bridge. Not sure if it is in the filling or clearing stage. |

platform is quiet and gently steaming. No audible sounds. SV runoff channel is white and dry. NV channel has a thin trickle of water. Cistern Spring is filling. water level is about 1.5' below the rim of the inner tube and has a vigorous boil.
** Interesting "newish" this year breakout thing down at the bridge! (edited for those who didn't like the word NEW!) About 20' below the boardwalk, In the NV runoff channel, is a new steaming feature! It looks like a blow out hole! Fine debris built up in a berm around a newly excavated hole with bigger chunks of rock in it. It is the shape of a bath tub, about 3' by 6'. There is a new damp runoff channel that is black and dark gray in color and runs toward Tantalus Creek in 2 channels. Looks like the runoff channel meets up with Tantalus Creek somewhere in the grassy meadow west of Cistern Springs. Above it, north, toward the bw @ the bridge, is a fine deposit of gray mud. It has a strong odor and the steam leaves a very bitter taste in my mouth. It looks like it erupted, excavating a bathtub sized hole, produced runoff and scattered debris! I can hear a hissing/huffing sound. Steam is coming from a side vent and from a depression within the blowout zone. I have photos! |

Did not hear start from Madison CG. Forcefull steam from NV, SV steamy but less force, light runoff in both channels. Beautiful sunny morning with both decks iced up with icicles everywhere.. Cistern down 20-24" below runoff, clear, no bubbles or boil. Heavy continuous SV runoff cresting shoulder of middle rock. Trough is mostly empty including gravel pit closest to bridge. NV runoff below bridge has eroded remarkably from last year.
0759 water returning to NV, jetting 50-80' and ejecting small rocks .0804 granding, pausing, hoth vents back to water. nv bursting 60 -80' and SV continuous 30-40+'.0808 slight pause, then NV vert to 90+', sv mixed with water still 30+'. 0842 SV turning to mostly steam, past half hour hs been water30+' from SV. NV has been consistently "Granding" 20-80', with some reaching 100'.. 0850 SV returning to water.

Others have more detailed notes about minors as my time at Steamboat was short. In my time at steerage there were several strong flows that moved golf ball size rocks down the channel and overall the overflow was pretty good, though coming mostly from South Vent. North Vent a few vertical splashes during this span, with occasional sustained angled play. We also noted that the grumbling sound could be heard from the lower platform. Also of note was that the "glaze" deposits similar to those observed in late July/early August 2018 were starting to appear in the channel at steerage, but I do not know when that started. |

Strong concerted minors with vertical surges (Woo-hoos) were seen today at: 0944, 1007 (not as strong as the others), 1110, 1231 (this one was a series of 2), and 1406. We saw a nice vertical series 1609-1620 that produced “raging rivers” (strong runoff). Today & the 2 previous days we often saw long periods of quiet weak minors in between the strong minors. I didn’t record when we first saw the milky coloring begin near the South Vent but I believe it was at about 1400. We all left on the early side due to a windy snowstorm. |

NV initiating with SV joining in within seconds most of time. Continuous babbling runoff at steerage from 2032 to 2040 with a raging river at 2035 after a sustained bursting. SV burst to tree tops from mid deck concerted with a somewhat shorter NV that was sustained enough to cause an audible raging river about 2045. In short time I was there, mostly shorter and angled bursts though many were concerted. Heard Sandhill Cranes in the basin. |

Both vents active, mostly SV with angled NV. 1814 sustained solo sv with strong runoff. 1821 strong Concerted Minor seen from steerage, moderate sv runoff. Trough has less debris than last observed by this writer. 1825 another CM, no vert. from NV. 1828 solo, sustained SV with heavy runoff in left side of channel. 1833 another solo, sustained SV with runoff covering middle rock.1842 sustained vertical SV, followed by concerted minor with NV vertical seen from mid deck. Activity increasing. 1901, past 20 min has been frequent angled concerted, nothing strong, or with any substantial runoff. Big concerted minor as we turn to leave. Typical of the fickle b***h |

From steerage: the Trough is dredged to bedrock right under the run off channel. quarter size and bigger debris collected just in front of the bridge. It looks like SB had some nice minor activity overnight as the run off channel had running water with ice formations all the way on the left side. Impressive run off at Steerage all morning. Nice concerted minors with impressive SV runoff but most of the play is SV dominated. 2 NV vertical play at 1104 & 1140. We will stop on our way home tonight. more later. |

Post eruptive observation. Both vents still in continuous water phase. SV 10 -15', NV 30 - 50' steady continuous water jets. Nice grumbling sounds. Constant stream of runoff down SV channel. The steaming vent to the south appears larger than last fall and is huffing steam. @1319 SV runoff channel is damp but no longer has water. SB is fluctuating between water and steam and is quieter with some huffing sounds. Cistern Spring is 4' below the inner tube and the pool is clear and blue. It has some gentle bubbles on the west side. New thing to note > On Jabba's south ear there are 2 new small areas (vents?) that we observed steaming today. @1315 Cistern Spring pool has dropped another 4". Emerald Spring is a BEAUTIFUL turquoise greenish color and calm. |

No eruption yet.
Looked about the same as Tues. With, possibly, one notable exception. In my very subjective opinion, sometime before 1530 silica started to rapidly accrete in the runoff channel, turning it a slightly greyish white. By ~1800, it was white all the way to the top of 'bottom rock', with some faint zebra striping in the first 6' or so of the delta. The breakout springs just S. of Vixen also seemed to be much more silica-laden as well. With the one closest to the boardwalk being a gorgeous opalescent blue. This may imply an influx of hotter silica saturated waters. Or not. IIRC, this phenomenon [whitening of the r-o channel] was first observed following last year's disturbance. Either just before or during the 7/6 major. Trough substantially dredged, but runoff flow has changed quite a bit from last Fall. 'Amphitheater' on right side of trough still pretty full. Still about 4" of gravel covering area between trough and bridge.
Edit:@Tara I definitely had that note in mind. As well as Udo's 7/6/18 entry "What's different with this from the others I've seen is this runoff was milky, not muddy..." and Bill's 7/7/18 note "There is a steady flow of milky water in both runoff channels at the bridge..." Neither of these actually talks about the color of the r-o channel itself, just the r-o. And I wasn't there on those dates. So I probably conflated all three. Who's to say what I was thinking, really? My apologies for any confusion this may have caused. But I think my pseudoscience supposition still stands. |

Steamboat continues to progress, although at a slower pace than the past several notes. When I arrived at Steamboat at 1730 There had just been a nice Woo-hoo! minor that was apparently the best activity of the day as reported by RMichaels and Tom C. At 1737 there was another Woo-hoo! That put a nice surge down the runoff channel. Throughout the rest of my detailed note taking from 1730 until 1830 there were no more Woo-hoos. The activity is dominated by South Vent which is voluminous and frequently sending up brief vertical jets that sustain for perhaps up to 5 seconds. No more 4 volume washes were seen down the runoff channel to the end of the detailed note taking section (1830). But at 1845 there was a nice Woo-Hoo! Minor, and things began to pick up a little. A brief lull of a few minutes was suddenly ended by two consecutive HOLY CUSS events at 1900 and 1902 that sent a flood of dirty, debris-filled water down the runoff channel and made some pretty good progress on dredging the trench some more. These were the two largest events of the day and this interval observed by far. Still, the activity is mostly voluminous concerted eruptions with a few mediocre vertical shots occasionally interrupted by Woo-Hoos! I remained until 2015 to see if there would be any more OMGs or HOLY CUSS events but there were none. |

I observed Steamboat from 0810 until 2015. Per a report from another observer who arrived earlier, Steamboat had a couple of concerted sustained vertical minors at about 0730. At 0935 there was a concerted minor with sustained vertical in South and briefly sustained vertical in North (a woo as opposed to a woohoo, to use the common parlance). There was a concerted sustained eruption from both vents at 1037 (woohoo). There was another peak in activity from 1320-1340, but it was mostly dominated by South Vent. This type of activity categorized most of the afternoon. South Vent had sustained vertical minors with good runoff. North vent had good volume and many of its minors were concerted with South, but none had large or sustained vertical play. This type of energy waxed and waned on about an hourly cycle for the better part of the afternoon and evening. There were strong minors at 1737 (woo) and 1805 (woohoo). At 1845 there was another strong minor (woohoo), followed by a huge false start at 1859. The 1845 and 1859 events came after a long period of North vent having angled minors with very good volume in concert with sustained vertical minors from South. The false start was followed by another powerful minor within a minute or two. After that the activity slowly quieted down. North vent still had some vertical minors, though they grew less frequent leading to my departure at 2015. In short: no eruption yet. |

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. |
