Intermittent forced steam huffs from Red vent similar to early Monday morning 29 June, 3 days ago. White vent quiet. Palm pool almost at overflow. Note that Red vent is white now so we may need to revert to Tube vent again. Sounded like a plane taking off every 30s. Not audible from parking lot but noisy up close. |

In roaring steamphase with some considerable force and noise to it. I saw a lot of steam through the Norris museum on my way out from the Steamboat check and decided to take a look. I did not notice this much steam on my way in, although I think it is more likely that it started before I got there. |

Seems to behaving much like last year. It cycles between steam with wispy water and brief quiet periods. Runoff channel directly below the vent is dark gray and has flowing water in run off channels. The periods of quiet with no water are very brief. Jetsam pool is very high & overflowing to the west. Jetsam side vent is erupting to about 5" above to pools surface. Palm pool is high and overflowing. Valve vent is steamy and loud, no water. It quiets when ledge gets quiet. |

Ledge in an extremely loud steam phase during this time and had not ended when I left. A park visitor reported it had also been roaring during her hour long walk before I arrived. She reports getting spritzed (my word) but saw no water eruption. I also got spritzed (soaked, really) when I got next to it about 1923. Walkway soaked. Trees across from walk coated in gray as was the Fumaroles info sign. Catch basin full and trickling into Jetsam which was also full. Main roar was from (what used to be a) red vent. |

When walking back from steamboat to check it’s activity I heard the steamphase of ledge from emerald, then I walked down to porcelain basin and saw that ledge geyser was in a vigorous and loud steam phase. Didn’t see much water downhill from it so I can’t confirm it was a water eruption or just steam phase alone. |

Audible steam ftom empty parking lot at 0530. Spraying steam from 3 vent, forcefully from "white" disc vent, cyclical forceful increases from what used to be red vent mixed with a bit of spritz. Kept that up as I walked around Porcelain. |

Ledge is doing the same cyclic behavior of steam (not loud) to mixed steam/water phase and then back to all steam without much of a pause inbetween. Palm pool is down 2' and Jetsum is down about 2'. Valve has steam with a bit of water and is putting water down into the Palm pool. To this observer, the runoff channels show no indication of a full blown water eruption of Ledge. More so, they are a result of the constant runoff since April 28th steam phase only "thing". |

ledge's water cycles have more water, its eruptions are broader and taller than last observed. Water cycles begin with steam phase hissing followed closely with jetting water 15' - 25' then more steam hissing, more water and then a VERY brief, 10 - 20s, quiet period. cycles resume quickly thereafter. |

ledge is still huffing/hissing a steam water mix. More water in the mix than last observed but it is still a thin stream of water mixed in with much more steam. heights of 8' - 10'. Palm pool high and starting to overflow. The water level in the hole between Palm and Ledge is high and has some runoff. Valve is steaming. |

Ledge is alternating between semi quiet state to hissing mixed water/steam phase. The water in this mixed steam/water phase is a thin veil of water that is 4' - 8' high mixed in with the hissing steam. The runoff channel is wet with some pooling in the flats. Palm Pressure Pool is very low - down 4 - 5'. Jetsum pool is high and almost overflowing through the channel on the SE end. There is a hole between the Palm Pressure pool and Valve vent that I've not noticed before. |

The Pit (Palm pool) is high and clear. Valve is spritzing water to 8" and a bit thicker than on 8/22. A wisp of steam observed from Ledge. Jetsam pool is high and green in color but its side vent that was very active earlier this year is only sending out small convection waves. |

But what I wanna know is what is cycling that I see Jetsam empty or full? |

From 3/4 full 2 days ago, Jetsam completely empty. Leaving at 1800 water activity in White vent actually looked pretty good. It occurred to me that we shouldn't rule out the No-Steam Phase eruptions (two seen this year) and keep an eye on water levels in Jetsam if it is seen brim full and all vents quiet. There may be some odd-ball eruptions still possible. |

Ledge has not gone. NO water at all, just light steam in Red Vent; some water with steady steam from White. Pit full and overflowing; Jetsam still 3/4 full AND the shoulder vent was quite vigorous unlike a couple of days ago.

Day Ten - at 1100 Pit was in overflow, Jetsam was higher than last night. Over the course of the day Jetsam continued filling, covering all formations. Water in White looked OK. Formation below Red was wet, but that could have come from Black Growler or drift from White - - I never saw any water from Red, but I didn't dally there on my mission to study Whirligig's new incarnation of vent indicators. Not sure when my next visit will be! |

Day Nine - White vent was putting out a little water, Red vent steaming. Jetsam half full (half empty?), but might have filled a bit with those spritzes over the course of the day. The Pit not in overflow. The water in White looked much better when I left, totally wetting the white shell-like formation, but not what I would have called "good water" last week |

No Ledge yet as of 1515 when I left radio range. At 1450, the Pit was near the rim but not quite overflowing. Jetsam had visible water but was low. White Vent was pretty juicy, and Red Vent had some large splashes with enough water to make runoff every 2-10 minutes. |

DaveM and I checked Ledge on Day Four. Dry. The Pit was lower at 1720 than it was at 1000, just two connected 18" circles that look like large sunglasses. Jetsam's shoulder vents were active, and Black Growler was moist and putting out a little water, but not much. The wettest White Vent was all day was after a soaking thunderstorm. In short, it's not ready yet. |

Stopped in morning and evening - this morn The Pit was as low as I have seen it, particularly on "Day Four". This evening if it could be possible it was lower! White vent had periodic forced dry steam, I didn't stay to time them to see if they were regular. I can't go tomorrow, I hope someone can check it and we might find out when (if?) water returns to the system and White starts spritzing again. |

Arrived to Ledge at 8 or so, Jepsam was low, White Vent had more steam than water, and saw Red vent splash once after watching it an hour. After returning from Vixen around 11 the situation had not changed. |

Bob Jones called me by satellite phone at 1610 to report no Ledge yet. Red Vent is splashing water every 4 minutes on average. Pit is full and overflowing into Jetsam. He'll call again if there is an eruption. |

Never seen Ledge erupt so take this with a few grains of salt. White was in continuous steam with water spray to about 10in 60% of time. Pool about 5ft in front of White about 8in below it's inner rock rim. No over vents showing steam or water. |
