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 |

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. |

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.) |

Arrived at the steerage early in the morning. Whole day was categorized by larger events compared to last Monday.
The day seemed like it was having mostly angled south and a lot of aggressive and kinda bouncy stuff out of north.
Spaced about 15?minutes apart from one another or less. I was not keeping track of time. There were 3 events that created 5 level runoff. At about 1100 was the last one that was a “soil your underpants moment” as I termed it. Huge, vertical, sustained out of both vents that didn’t seem to have any follow up or lead up. But not quite tall enough or sustained enough to initiate. I even thought it might start but it did not.
It then went into a lull that lasted for about 5 hrs until about 1630 when some angled and vertical minors were occurring that wouldn’t follow up but peeked my interest. A lot less runoff than in the morning with 2-3s and when I left at 1815 from the steerage, it seemed to be coming back a little bit but not making me excited. So I decided pack it in and come back the next day. |

Large minor with a 4 overflow reported by others at 0720. Then pretty quiet until 3 large minors: 1027 sustained NV vertical and long SV duration, 5+ overflow; 1045 strong vertical from both vents and 5 overflow; and 1106 tall, wide NV vertical with heavy SV runoff, 5+ overflow. After that max flow reported from steerage was 2-2.5, occasional bounce but not sustained before I left the platform at 1345. Thanks Emily W for reports from steerage. |

Some very decent play. very sorry, I did not note times. But two decent events. I am not great on what events are called but head a very good push vertical north sustained south, a lot of water and runoff. We were surprised it didn't erupt during the first push. Second "event" shorter with decent vertical. runoff less as south was not sustained as long.
Dimitri, Will and a couple others remained and will monitor over night. |

4D 21H post eruptive. According to early morning gazers SB has had a few babbling brooks and 1 minor that had some vertical. Steamy this morning so its hard to view the vents play. Good runoff and nice percussive grumbling. @ steerage the stick is 12" exposed and it looks like there has been minors that put water over to the left side of the bridge that went under the bridge and extended out 3' past the bridge. Trough is still collecting debris down the runoff channel. Run off on the Micah scale was 2.5 during this observation period. Cistern Spring pool is high with good overflow and a 2 point boil. |

3D 21 H post eruptive. water has returned to the system. SV runoff channel is wet to the bridge. NV has a few angled splashes 15 -20'. SV has some strong angled jetting, enough to roll debris down the channel. back shoulder is wet. @ steerage the channel has a thin but constant trickle of water. The runoff channels in the delta beyond the bridge have standing water to the first little grouping of trees. Cistern Spring is still high, overflowing in all directions, with a mediocre boil. |

SB had one 5' weak NV splash. SV spritzed a bit. Both runoff channels are dry as a bone as is Gabba and ET. Cistern Spring is in copious overflow out all sides + the pool in between the boardwalk and CS. It has a mediocre boil. |

21H 20m post eruptive. SB is quiet. gently billowing a large column of steam but vents are quiet and channels dry. The bw from the bench to the platforms is VERY wet! Cistern spring is empty, no steam, no water, no sounds. The trough is 90% dredged. still a bit of debris in the out flow basin. stick is 16" exposed. |

Arrived at about 530 in the morning to the platform. Didn’t pay attention for the first two hours or so of the sit as I was running around from the steerage to around the basin trying to warm my cold wet feet.
But then I grabbed my book and was sitting at the base of the steerage for the rest of the time until the start of the major.
Runoff from that vantage point did not seem any different than the previous day. Seemed like there was some good runoff overnight based on wet channels but nothing seen in the morning that seemed to match this runoff.
It wasn’t until about 1037 or so when the minors and runoff started significantly increasing. The runoff stayed at at least a 2.5+ to 4 the whole time until the start of the major. Even when the vents were quiet the runoff dId not cease. This of course built with the size and verticality of the minors that eventually initiated the start of the major at 1047.
Start was an amazingly tall and rumbling start from the steerage. Absolutely awesome. Looking forward for a shot for the Labor Day crowd this weekend or perhaps Monday or Tuesday.
GO STEAMBOAT! |

Spent most of My day at the steerage. Mostly angled south and north. There was also only one occasion where what I would call a 4 on the runoff scale occurred and that was at around 1230 when there was one of the only true NSSV large minors that made me stand up. Most runoff was at most a 3 and and most of the time a 1-2.
It seemed like south would have sustained angled minors to about 20’ without north. And sometimes north would have a large vertical spike but would not sustain. This seemed like the activity in the morning. Most of these sustained angled south produced 2-3 runoff.
There was one event at 1230 ish that produced the above observation.
It then wasn’t interesting for the afternoon until later on around 1630-1730 north finally got some bounce, verticality, and size and south vent was not sustaining or putting out much water at all.
This activity culminated in 2 large but still kinda eh minors with no follow up and imo was the most interesting thing all day.
Seemed like it went into a lull after that. Left at 1830.
Never seemed enthusiastic about initiating a major eruption when I was there.
Hopefully tomorrow. |

Almost constant water down SV channel at bridge. Pool there looked empty of much gravel but I will defer to those more knowledgeable about that. Water pooling to right of the main spot at steerage. NV & SV low and angled every 1 to 2 min but not starting together. NV mostly initiating. Not tall but lots of water rushing down hill. NV channel dry. Base of tree and edge other side of NV bridge still steaming. Cold morning so SB water somewhat shrouded at times. Area behind and to right of SV damp. Maybe 3' x 3' square of white string secured to ground just below mid-deck Steamboat sign. |

3D 18.5H post eruptive. Water just entering the system. SV runoff channel is damp about 15' from the vent but bone dry from there down to the bridge. Occational small splashes from both vents. Nice bellowing steam and rumbling sounds. Cistern Spring pool is high, clear and in good overflow. (trickle of water into the muddy pool) The steam coming from the NE side of the berm, below the bridge, in the NV runoff channel has increased. It emits a wonder pine essence! |

slight increase in activity from the previous few hours, with a decent concerted vertical minor, enough to give me pause about leaving, then several follow-up minors, each decreasing in energy for about 30 minutes. |

Minors picked up with concerted vertical sustained activity at 1356, 1510, 1517, 1534, 1541, and 1628 At 1712 NV surged to 75' with sv vertical to 40' for 20-30 sec., in what was as close to any start we have ever seen, without erupting. NV totally shut down and SV continued for a full 15sec at 40'. Both vents then fell silent, not even any steam, for 3 min. Exposed 8" of stick in trough from single runoff. Concerted sustained vertical minors resumed at 1728, 1755, 1846, 1936, 1957, 2024, 2047. |

5D, 9.5 hrs: Both vents active, few concerted. SV runoff steady light flow, and has rolled enough gravel to cover the stick at steerage. Cistern is very high, overflowing into muddy pool. 0921 first concerted sustained vertical minor with heavy runoff (4). More large minors at 1026, 1058, and 1152. NV and SV sustained voluminous solo's occurring regularly. |

4D 18.5H post eruptive. walked up to a concerted NV SV minor with a bit of bounce. NV ~ 25'+ & SV 10+'. SV runoff channel is wet to the bridge & the back shoulder is damp. The stick at steerage is 12" exposed with much of the debris in the trough gone. @ 1656 & 1702 a CNVSV that rolled lots of pebbles and pine needles into the trough. steady SV runoff. Cistern Spring is a cloudy, milky, opalescent blue pool. it is in overflow with a moderate boil. |
