25D2H.. Steamboat is doing much the same activity as I've observed in the past few days. Strong huffing of steam from both vents but predominantly NV. NV is a mix of steam and both angled jets and strong vertical bounces of water. SV is mostly all steam with an occational wispy spritz of water. SV channel is very wet ~10' below its vent and mostly dry above it. There is a thin trickle of water that appears to be coming from a steaming vent somewhere below Jabbas right jaw and flows down the far left side of SV channel. Channel is wet with a continuous trickle of water to the footbridge and beyond. Back shoulder is dry. This note is taken before any rain overnight. Cistern Spring is the same >low pool, weak boil, overflowing toward Echinus and a bit in a low spot toward Veteran. |

quick note. Very little water if any from either vent. mostly just occational steam. viewed off and on from Decker. SV channel is bone dry. Trough has some residual pooled water. EMERALD SPRING is at the same water level, down 4" from overflow, clear, calm and more blue than green. CISTERN SPRING is also the same. Only overflowing out the channel toward Echinus. weak boil. |

17D2.5H.. SB is forcefully huffing mix of steam and water from NV, SV mostly steam. SV run off channel at the top, just below the vent is bone dry, 15' below the vent the channel is damp. I believe this is from NV splashes coming over the "dip" (Jabbas left ear) and running down the lefthand side of SV channel. Very little water in SV. CISTERN SPRING is still low and barely in overflow with a weak boil. EMERALD SPRING is also the same, pool 3-4" below overflow, clear, calm, green. |

16D12.5H.. SB is huffing forced steam with some bounces of water from NV to 5' and mostly airy spray with bigger water droplets. Nothing but steam from SV. Both channels are bone dry. CISTERN SPRING is only barely overflowing out the established channel toward Echinus. It is cloudy blue with a very weak boil. EMERALD SPRING is still ~3-4" below overflow. It is clear, calm & greenish in color. The 3 Trees feature along the east edge of Emerald's runoff, close to the boardwalk, that I have watched for 3 years is putting out a little bit of water down Emeralds channel, but not much! No boil at all. The sputter in the green algae 3' toward the Museum is inactive. |

14D3H.. Steamboat is gently huffing steam. NV had a wisp of water in 1 huff. SV channel is damp in places but dry around the vent. Trough has water but I believe it is from rainfall, same with patchy dampness in SV channel. CISTERN SPRING pool is low and is 1" below overflow in most directions. The established channel toward Echinus has a weak flow of water. Cistern has a weak boil and is a cloudy turquoise blue color. EMERALD SPRING is very low. pool is still down ~4" below overflow. it is calm, greenish/blue and clear. |

35D22H. Both vents are active. Still NV dominated with tall, sometimes vertical play. SV has good, angled, jetting that is putting out some babbling brooks. Evidence of some nice SV play before I arrived as the SV tributaries below the bridge are wet and have pooled water in low depressions. Very typical of good activity I've observed.... then it drops off to a dismal trickle. Green algae is forming in SV channel ABOVE the trough and extends 30'+ below the bridge & it is most dense in the trough and 6' below the bridge. Emerald spring is clear, calm and overflowing. Cistern Spring water level is just at or barely below the scalloped edges (sinter rim) of the pool. It is overflowing out the established run off channels and a bit out the backside and toward Veteran. Color is blue and it's clear with a vigorous boil. Muddy pool is devoid of water. |

34D+. SB is having very active periods followed by inactivity. Active periods have tall, NV angled and vertical play accompanied by SV angled and aalllmosttt vertical, tall play. SV is currently putting out babbling brooks and several raging rivers. I have watched this play alot in the past few weeks and we get impressive action only to see it dissimprove directly afterwards. But, it is a holiday and.... :) 😀 There is more green algae in the trough and down the channel past the bridge. Cistern spring pool is low! Only over flowing out the established channel toward Echinus and barely over the back side. Surrounding edges of the platform are caked dry as is the muddy pool. Emerald Spring is low and BARELY overflowing. Event non-geyser related: >The Beverly's caught MANY cutthroat trout (22") in the past 3 days! |

30D+ PE. This morning SB activity looked better than yesterday with a bit more water in SV channel. 0930 runoff is back to a trickle at steerage. next activity was @ 1510 &1525. we had a nice babbling brook that dispersed water into the channel toward Echinus and a wee bit (viewed with binoculars) down the middle channel just above the dead trees. Activity slowed down to a trickle and I left. Cistern Spring has not changed since yesterday and Emerald spring is clear, calm, greenish and in very slight overflow. The green algae in the trough and just below the bridge in the cracks is spreading a bit. |

29D PE. Arrived to a very lack luster platform. Very little continuous water flowing down SV channel. Tall, sometimes vertical NV accompanied with angled SV. Babbling brook at 0829 & 0912. Activity decreased after that to snooze level! From noon to 1615 activity has not changed much. Occasionally there will be a SV minor that puts a meh river down the channel. Water at bridge is mostly a consistent weak trickle @ 1711. There is a bit of green algae growing on the right side of the trough on the sinter shelf. Cistern's pool has dropped a smidgen & is overflowing only toward Echinus and out the backside. It has a vigorous 2 point boil.. Emerald Spring is clear, calm & greenish. |

25D PE: Slight improvement from yesterday. Some solo and concerted SV play that put several babbling brooks down the runoff channel. Thicker NV, some were vertical. Cistern is a tad bit lower with dry patches on the backside and towards Veteran. A bit more rainbow sherbert colored algae growing above the muddy pool and much more orange colored algae in the Bobby Sox trees on the backside. |

24D+ PE. Pretty much the same as yesterday with MAAAYBE a bit more water out of SV, ON OCCASION. Still NV dominated with the occational SV that attempts to go vertical (big) but lacks water and strength. A few ok (meh) SV rivers but they are few and far between. Mostly just a steady weak stream of water to the bridge. Cistern spring is the same except the runoff over the shoulder toward the muddy pool has beautiful bacteria mat that looks like rainbow sherbet! Emerald is calm, clear and greenish blue. |

23D+ PE. This morning Steamboat looked more interesting than I've seen. Nice NV with some V and 2 reverse V bounces+. Some fuller SV's, 6+' with some nice rivers that have washed the pine needles off above the trough and has added some small rivulets that extend 8' below the bridge. This afternoon was lackluster. Small dry patches on SV channel that are dampened by weak rivers. All in all it is improving in spits and furtz! NV much more active than SV. |

13D20H PE. SB is mostly just billowing steam from both vents with an occational 20' angled jet from NV. Some NV water is landing in/on the dip (vertical spot on Jabba) and creating a damp, narrow stream of water that runs 15' down the far west side of SV runoff channel. This dampness in the channel is NOT from SV. SV channel is dry. Cistern Spring is the same, overflowing to the south and the backside with a blooping boil. Emerald spring is steamy, calm and in slight overflow. |

Steamboat continues the activity from the last few days with large, tall, and sometimes vertical NV (some of the verticals are fairly tall) and a lackluster SV. SV does occasionally have a heavier minor, and sometimes it is sustained and/or contains a vertical splash or surge. No sustained vertical and no large SV vertical. It seems that NV is often dragging SV along into doing something 'interesting' a lot of the time. It often accompanies nicer/decent NV activity. Gravel is accumulating in the trough but not being pushed out. The green bacteria in the trough & beyond has grown a little since last night.
Emerald cloudy this morning (low wind) but cleared up quite a bit by the time I left. It seems like it has been alternating btwn clear and cloudy each day for a while. Echinus has also been alternating clear and murky each day. It seems that whenever ES is clear, Echinus has been that cloudy filthy brown color from last year, and visa versa. The one note where I saw something sort of interesting from a few days ago, ES was clear and Echinus was murky. |

At 1128 there was a large minor with SV vertical and heavy, and NV vertical and heavy over 20'. Not sustained for long, and it crashed after. Washed a lot of gravel down the channel. The interesting thing was that afterwards, the water in the trough turned milky for a few minutes.
For almost an hour starting at ~1610, we had a nicer period of activity with fairly frequent SV vertical and a fair amount of nicely sustained ones. NV picked up too with an increase in strength and some nice, large vertical surges. Several concerted minors. SV may have even finished off a couple of them. I was at decker 2 so my view was slightly obstructed. No real sustained or tall SV vertical at any point. When I returned to steerage after, the pile of gravel in the trough was noticeably larger.
Still pretty quiet aside from that. ES is clear again, CS high with huge boil still. More later. |

Zero improvement, and actually worse than two days ago. South Vent minors were weak and infrequent, although there is still steady light runoff at the bridge. No more debris has been washed. North Vent minors were angled, some thick but no vertical. |

Better than yesterday. As Art reported yesterday, water in the trough is clear (it was cloudy yesterday morning). Right after 1100 we had an increase in activity. There were a few pushes that moved some gravel down the channel, and one that moved a significant amount down the channel. Probably the first distinctly "good" surge I've seen. It was followed up by a 10'+ NV vertical. The activity at 1100 was good enough to call a 'push' IMO. May have witnessed the end of a similar event after arriving back from lunch about 1400. SV hinting at vertical at times but still predominantly angled, and not sustained for long, if at all. Still thinner than I would like. NV still thiq and tall like yesterday but with more frequent and better bounce to it. Fair amount of concerted minors but SV never got strong enough to turn NV off. Weather was actually mostly dry today. |

Moderate improvement from what we saw yesterday. Nice surges from both vents from 1100 to 1130, a few small verticals seen from North Vent. No vertical from South Vent but some surges were thick with more discharge. Some debris moved down the runoff channel. |

NV remains broad, voluminous and occasionally vertical. SV plays in concert at times with steady runoff that is often moderate. No vertical seen from SV during brief stay. From the bridge l see no evidence of anything even approaching a 3 on the "T" runoff scale, other than a small amount of new gravel in the trough.. Water in the trough has cleared from this morning. Cistern remains very high and overflowing in all directions. Emerald is calm and clear, closely guarded by Harry this evening. |

Nice concerted north vertical, with south vent vertical to just over ET's head for maybe two seconds, with good, moderate runoff. First attempt at vertical from SV in the little time l have observed this interval. Nothing after that until l left at 1330. |

Did not see any improvement from a few days ago. Biggest change was the white in the runoff channel at the bridge. Steady light runoff from South Vent. No vertical seen while we were there. |

Almost vertical SV as I walked up with moderate runoff. NV still thikk and vertical. 3” new snow and trees down at a clear calm Emerald. Harry the Snowshoe Hare seen in the area. Cistern is overflowing into and out of muddy pool. Water at steerage is still milky, as reported by veteran SB gazer Clara last evening. Whitening of the SV runoff channel has reached the bridge. |

Couple of nice vertical NV minors. NV appears to have plenty of water but SV is entirely angled with only light to moderate runoff. Few concerted minors, all angled and none sustained. |

Afternoon observation was briefly encouraging. SV channel is whitening. Between 1330 - 1430 SV had 4 angled minors that put nice rivers down the channel but that was short lived. NV still dominates the platform with tall angled minors and an occational bounce. Cistern is at the same water level > high >overflowing in all directions > clear with a blooping boil. |

A bit of change at SB. Not much activity when I first got there. ~1000 - 1030 nice SV rivers. Hard to see the vent activity through the steam. It appears to be all angled minors tho. More later. |

SB activity is unchanged from yesterday, and the day before, and the day before etc! Angled NV eruptions and very few SV eruptions. No vertical.. Small rocks in the trough are in the same place. Debris is SV channel MIGHT be less in quantity but mostly still there. SV channel does appear to be lightening (white*ish). Cistern spring is at the same level I've observed for the last week. Pool is high, overflowing in all directions and lapping over the scalloped edges. Emerald spring is calm, greenish and overflow is not discernable at this early morning hour. |

Bizzare YNM trace starting around this time. Likely not steamboat since it is scratchy. Just marking for future reference. |

Looked very similar to yesterday: steady light runoff at the bridge, angled splashing from North and South Vents, North Vent dominant. At 0719, 0735, and 0749 there were bounces from North Vent and heavier runoff from South. For a 10-minute period at 1100 the angled activity from both vents became more frequent, but it subsided afterwards. No vertical and nothing sustained. |

Similar to yesterday morning. Runoff at the bridge was very steady but debris was still in the channel. A few more bounces seen in North Vent but nothing vertical. South Vent had a few heavier angled surges at 0959, 1305, 1407, and 1635 with heavier runoff but nothing sustained. Both vents had heavier surging (all angled) for a ten-minute period starting at 0959. Otherwise activity was mostly angled splashing from North Vent with weak splashing from South. |

Activity was similar to yesterday although in the morning runoff at the bridge was a bit heavier, but still not enough to push debris down the channel. In the morning activity from North Vent was more frequent and forceful, but still angled. A few bounces were observed, but nothing vertical and nothing sustained. South Vent was angled with no fountaining, weaker than North Vent. There was one nice surge out of South Vent at 1229, close to fountaining with noisy runoff but not sustained. With that one exception from South Vent, in general the activity weakened shortly after 11 AM with longer periods of quiet. |

Today was a repeat of yesterday. Only one significant push of N&S vents at about 1850 which resulted in a large runoff down the channel that could be heard all the way to the bridge. About 1920 there was a brief 10ft N vertical, without any angle, and accompanied by a S angled. |

I left st 1600 and there was no change from Suzanne's report. A few NV mini bounces and one SV river that had a bit of porpoising. As Tom would say... Meh! |

Slight improvement from what we observed yesterday morning. Runoff in the channel was a bit stronger, still steady. North and South vents still angled. I did see a couple of bounces from North but no high vertical and nothing sustained. No fountaining observed in South Vent. |

SB continued to have weak minors but were slighly stronger than yesterdays. A few angled minors from N to about 35 ft and S to 20ft occurred at 1851 and 1900 with strong runoff - stronger than yesterdays best. There were three brief 5 to 10ft verticals from NV occurring at 1126, 1156, and 1542.
Cistern and Emerald remain unchanged since yesterday. |

Angled splashing from North and South Vents, nothing heavy. No vertical surges, no bounces, no babbling brooks. Runoff at steerage is steady but light. Debris has not washed. |

No changes to BB's previous post except that the system had less energy after BB left at 1617. There were no vertical or vertical bounces during my observation. The runoff was slightly weaker. The debre in the channel remains unchanged since 1617 |

Continued angled, wispy play from both vents with hourly vertical splash from NV and barely audible runoff down SV channel. SV runoff never strong enough to move any debris down the channel. 1500-1600 slight upkick in activity; more frequent, but no stronger SV runoff, and somewhat thikker, more frequent, angled NV. 1550: NV bounce. 1556; first near vertical SV seen with runoff that moved any gravel. Several bubbles seen in Emerald's clear pool as we walked out. |

Mostly angled jetting from both vents with one or two small bounces out of NV. SV runoff improved some but no evidence of substantial water at bridge. Still has not rolled much of the debris down the channel. Shoulder is wet and steamy with trickle down back channel. NV wispy but occasionally somewhat thicker. |

Not much change since 1400. All angled jetting. No vertical. Debris is still in the same place in SV channel as was at 1400> so no good SV rivers have occurred to move it down to the bridge. |

Water is back in both vents. To steamy to read heights but both vents are angled spray. SV channel has a constant stream of water flowing. There still are a lot of small rocks and debris in SV channel so no really powerful rivers have washed those down the channel yet. Back shoulder & channel is wet. NV channel is WET with a slight trickle from the Pollys Pool area on down the channel. SV water is a constant flow at the bridge and a bit beyond unto the Delta. Trough is full of debris. Cistern spring pool is high and overflowing in all directions, especially out of the established runoff channel to the south. |

N&S vents sprayed water only 3 times during this observation. N to about 15 ft and S to about 10 ft, all angled. One of the S vent sprays pushed a small amount of water about 80ft down channel.
Cistern in light overflow with about a 2ft diameter boil 3 inches high.
Emerald Pool: clear and emerald in color, calm with no bubbles, it has a very light overflow. |
