16492 30 Oct 2020 @ 1429 --- steve Ledge is pushing out steam with little to no water.
16412 12 Oct 2020 @ 0358 --- cb Again Ledge woke me up in LOUD roaring, whistling at times, steam phase! I had to check the seismo to see if it was Steamboat but no signature on the graph so its obviously Ledge! A VERY loud Ledge eruption!
16411 11 Oct 2020 @ 1445 11 Oct 2020 @ 1530 jonp Intermittent periods of light water spray and forced steam
16403 10 Oct 2020 @ 1320 --- cb Ledge is fairly quiet today. Occationally cycling from very quiet to a quieter steamy roar (is that an oxymoron?) Jetsam is down 1' below overflow and is a murky light brown color with some scummy foam on the edges. Valve is gently steaming and the Palm pool is low.
16364 07 Oct 2020 @ 2100 --- cb I can hear Ledge in LOUD steam phase eruption from the trailer in the government area! It was not ie when I left the basin around 1830.
16350 06 Oct 2020 @ 1450 --- cb cycling between weak steam and a thin Vail of wispy jets of water. Valve spitting a bit of water but mostly whistling steam. Jetsam is a few inches below overflow and the side vent is erupting to ~6". Palm pool is low.
16261 26 Sep 2020 @ 0230 --- cb Heard it at the government area. LOUD roaring, thought it was SB but it was Ledge. 1410 Ledge is still is loud steam phase eruption. Runoff channel does not look like it had a water phase eruption. No eroded out channels. Jetsam pool is high, 3" below overflow
16241 23 Sep 2020 @ 1712 --- DanS In steam phase.
16222 21 Sep 2020 @ 1545 --- cb Ledge is putting out more water within the steam than yesterday. Still cycling between weak steam and a mixed water steam phase with a thicker Vail of water than I've seen this summer. Palm pool is higher (4" below overflow. Water running into it from Black Growler or Ledge?) Jetsam and Valve are the same.
16209 20 Sep 2020 @ 1531 --- cb Today it's quietly steaming but it occasionally has an energy surge and briefly roars for less than a minute. Jetsam pool is below overflow by ~1'. Its side vent is erupting continuously to ~4". Valve is gently steaming. Palm pool is ~8" below overflow and quiet.
16134 14 Sep 2020 @ 1042 --- Graham In noisy steam phase.
15899 30 Aug 2020 @ 1500 --- cb Ledge is in roaring steam phase. no water, full steam eruption and seems it's been this way for awhile. Jetsam is about 1' below overflow, palm pool is full and Valve is in a milder form of steam phase.
15700 23 Aug 2020 @ 0610 --- ypcaribou Roar heard from start of path at parking lot. Still roaring at 0845 when I left basin.
15685 22 Aug 2020 @ 0130 22 Aug 2020 @ 0645 cb I woke to hearing ledge in roaring steam phase eruption. Road noise made it impossible to hear after 0645. @1630 Ledge is still in roaring steam phase, albeit quieter. No water, just steam.
15629 17 Aug 2020 @ 1650 --- cb ledge is still cycling between steam and a thin spray of water and then is quiet with just a little steam. Jetsum pool is 1' below overflow. The vent on the SE edge of the Jetsum's pool is still active and erupting 8" - 10" in height.
15545 13 Aug 2020 @ 1130 13 Aug 2020 @ 1159 cb cycling weak steam with a thin vail of water. Not very strong and not loud
15499 10 Aug 2020 @ 1340 10 Aug 2020 @ 1445 William post eruptive steam, boardwalk soaked.
15137 01 Aug 2020 @ 1142 --- Mkeller In and out of weak steam phase between 0810 and 1020.
15055 20 Jul 2020 @ 1630 --- Yates Very powerful steam, heard from the museum. Seemed to lose power and walked away after about 6 minutes, could still be heard from the bookstore on my way out.
15028 18 Jul 2020 @ 1330 --- Mkeller Ledge mostly quiet between 0550 and 1330. A few moments of forceful steam but quiet around 75% of the time.
14971 13 Jul 2020 @ 1308 13 Jul 2020 @ 1504 nails Loud forceful steam. Quiet pause at 1321, 1329, 1336, 1347, 1357, 1408, 1416, 1429, 1448, 1458, 1504
14915 09 Jul 2020 @ 0535 --- RMichaels Ledge is in roaring steam phase, audible from parking lot. Pressure Pool and Jetsam Pool are both overflowing.
14866 03 Jul 2020 @ 0559 --- Graham Continuously venting steam from Red/Tube vent, not forced and noisy like yeaterday.
14857 02 Jul 2020 @ 1543 --- Graham 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.
14777 29 Jun 2020 @ 1110 --- Graham continuous steam from Red vent but much weaker and no longer forced or noisy.
14775 29 Jun 2020 @ 0900 --- Graham Red vent in cyclic intermittent forced steam for about a minute, then gentle steam for about 30s. White vent has occasional drifting steam. Pressure and Jetsam Pools full.
14686 19 Jun 2020 @ 2129 --- Ben VL 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.
14601 11 Jun 2020 @ 1648 11 Jun 2020 @ 1730 cb 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.
14757 09 Jun 2020 @ 1000 --- K.Cooper Post eruptive behavior, extremely powerful steam phase with occasional episodes of "water phase" that would soak everything downwind a few hundred meters.
14542 05 Jun 2020 @ 0903 --- bbev Red vent in heavy steam, can be just heard from the bookstore. Jetsam pool full. Palm pressure pool high and overflowing into Ledge runoff channel
14511 03 Jun 2020 @ 0610 --- ypcaribou Forceful, loud steam has stopped. Still billowing steam, just not loud. As observed from Museum overlook.
14492 02 Jun 2020 @ 0745 02 Jun 2020 @ 0930 ypcaribou Still in roaring steam as seen from museum at 0745 & 0930. Sounded a bit quieter at 0930 but still noisy.
14493 01 Jun 2020 @ 1855 01 Jun 2020 @ 1932 ypcaribou 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.
14246 26 May 2020 @ 0800 --- Janet Jones He said it was behaving post eruptive with blasts of steam.
14034 16 Dec 2019 @ 1430 --- ypcaribou Path by Ledge closed. It is very active and steam has created an icy walkway.
13915 10 Oct 2019 @ 1620 --- underarockphoto In roaring steam still
13872 04 Oct 2019 @ 1230 --- underarockphoto Steaming. Roaring surge every few minutes that was audible from Whirligig. Pool is almost empty.
13796 24 Sep 2019 @ 1445 24 Sep 2019 @ 1650 DanS Red main vent heavy steam with water spritzing to 10+ feet. Trail very wet.
13745 19 Sep 2019 @ 0751 --- bbev Roaring steam heard from parking lot and museum. Jetsum remains 2' below overflow and pressure pool has dropped to nearly empty, 18" below overflow.
13737 18 Sep 2019 @ 1600 --- bbev Ellen's video clearly shows red vent jetting water 50+'. 1600: forceful steam from valve and red vents. runoff channels are all wet. Jetsum pool is 2' below overflow, and palm pressure pool is 6-8" below overflow.
13561 04 Sep 2019 @ 0823 --- novakg Very noisy steam heard from Constant bench.
13240 14 Aug 2019 @ 1115 --- cb Ledge is cycling forceful steam - quiet moments back to steam and then quiet. Palm pool is empty and dry. Jetsam is down 2.5', its side vent is spitting water 6" and the vent on the west end of the pool has bubbles breaking the surface. Valve is gently steaming.
13139 09 Aug 2019 @ 2048 --- hurleyintjl 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.
12895 31 Jul 2019 @ 1030 --- cb powerful and loud steam only. minimal water in runoff channel. Seems to cycle in volume. Jetsum & Palm pools are high (full) valve in steam.
12847 28 Jul 2019 @ 0556 28 Jul 2019 @ 0600 ypcaribou 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.
12548 20 Jul 2019 @ 1000 --- cb 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".
12520 15 Jul 2019 @ 2127 --- mhreed Ledge is in vigorous steam phase.
12490 15 Jul 2019 @ 0744 --- cb In steam. No water seen in the steam. some water in runoff channel and down to meet the main Porcelain runoff channel. Palm pool down 2". Jetsam down 4"
12106 02 Jul 2019 @ 1900 02 Jul 2019 @ 2023 DanS Ledge steaming and throwing variable amounts of water from both white and main vents.
12086 02 Jul 2019 @ 1916 02 Jul 2019 @ 2011 nails Less water mixed with steam than noted on 6/30. Occasional nearly quiet pauses with only gentle wafting steam. Vent upslope between Ledge and Valentine/Guardian alcove joined in with mostly noisy steam and a brief bit of water at 1934.
12053 30 Jun 2019 @ 1741 30 Jun 2019 @ 1937 nails Intermittent light water noisily mixed with steam. Vent uphill between Ledge and Valentine/Guardian alcove joined in at 1800, 1904, 1931.
11828 16 Jun 2019 @ 1056 --- cb 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.
11489 02 Jun 2019 @ 0540 --- Graham White vent putting out noisy hissing steam roars every few seconds. Gentle steam from Red vent. Pressure Pool is full.
11384 27 May 2019 @ 1704 --- jkgood Fine jetting up to ten feet out of red vent
11348 24 May 2019 @ 1829 --- bbev Mixed water and steam, water spritzing to 10+' at times. Palm pool overflowing. Hole between palm and red vent nearly overflowing. Jetsum just at overflow.
11311 22 May 2019 @ 1706 --- cb 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.
11279 18 May 2019 @ 2040 --- Kyle intermittent "swooshing" light steam from both white and red vents. no water visible
11245 15 May 2019 @ 0950 15 May 2019 @ 1405 cb 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.
11174 05 May 2019 @ 0950 05 May 2019 @ 1003 bbev Red vent cycling from quiet to soft roaring steam about every 15sec. Side hill vents can be heard gurgling and water seen out of both. Upper vent most active. Palm pressure pool down 8-10" below overflow. Jetsum unchanged.
11157 03 May 2019 @ 1924 03 May 2019 @ 1933 cb Ledge continues to get quieter. Still in steam phase with audible roar but we can speak in low tones and still hear each other. Palm Pressure pool is 2 - 3" lower. Jetsum pool a boil with bubbles on the west end of the pool. Valve Vent is still in steam.
11143 02 May 2019 @ 0928 --- MAB still roaring from both vents
11141 01 May 2019 @ 2025 01 May 2019 @ 2100 ypcaribou Audible roaring heard from quiet, empty parking lot on arrival at 2025, from museum at 2055, and from lot again at 2100.
11122 01 May 2019 @ 0804 01 May 2019 @ 0820 cb still in steam phase. quieter but still can be clearly heard from the Ranger Station
11124 30 Apr 2019 @ 1000 --- cb Still in LOUD steam phase
11119 29 Apr 2019 @ 0755 --- cb did a quick parking lot drive through as we could still see alot of steam in the Ledge area as we passed Elk Park. Stopped and can still hear Ledge in steam phase. LOUD STEAMPHASE! No time before work to walk down.
11026 20 Apr 2019 @ 0917 --- MAB Valve vent in very wet, noisy forced steam.
10725 04 Nov 2018 @ 0905 --- MAB While watching water spritzing out of Valve (finger-white) vent, I suddenly noticed Black Growler was quiet. Totally. Zip-nada-nothing. Walking on, it came back on as I was just about at Basin Geyser.
9868 25 Aug 2018 @ 1051 --- cb 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.
9830 22 Aug 2018 @ 1730 --- cb the white heart shaped feature (Valve?) to the left of Ledge is spitting water and Ledge is lightly steaming.
9828 22 Aug 2018 @ 1723 --- MAB The Pit (Palm) pool is filling, it has been ugly dry most of the summer. Water is spritzing out of the Valve vent, sometimes heavy. Saw steam from Ledge main vent. What's next?
3183 02 Jul 2016 @ 1027 --- MAB 1027 and throughout day - spritzing from White Vent. Water has returned to Black Growler too but not enough to kill the yellow/green near upper vent
3081 16 Jun 2016 @ 1014 --- MAB Ledge totally dry of course but White Vent emitted a harsh steam whistle when I walked by, then it subsided.
2594 31 Oct 2015 @ 1000 --- MAB The penultimate Ledge note! The Pit overflowing into 1/4 full Jetsam. Fairly good water from White Vent. Nothing seen from Red Vent. Jetsam shoulder vent active.
2587 29 Oct 2015 @ 1325 29 Oct 2015 @ 1340 billwarnock Steam and occasional water from White; no water, light steam only from Red during my short stay. Pit full and overflowing into 3/4 full Jetsam. No water seen from Black Growler. Light snow and COLD.
2577 24 Oct 2015 @ 1735 --- MAB Day Two-ish?: Jetsam about 18" below full. The Pit very empty, below the rolled log sign. Red Vent calmly steaming. White Vent formation is dry, the actual vent orifice looks wetter than yesterday. Forced steam from Black Growler but no water seen.
2504 10 Oct 2015 @ 1658 10 Oct 2015 @ 1822 Siegmund Pressure pool overflowing. White vent emitting steam mixed with a few water droplets. Red vent dry and quiet. Jetsam nearly full, Jetsam sputs active. All in all -- just like White Vent looked last year when it was dormant.
2482 05 Oct 2015 @ 1030 05 Oct 2015 @ 1852 MAB On arrival Jetsam 1/2 full with just the 'nib' of the formation showing. Good water in White vent seen at various times thru the day. Leaving at 1851 Jetsam had filled to 3/4 full, the formations all completely covered. Green around the base of White vent continues to grow. But what I wanna know is what is cycling that I see Jetsam empty or full?
2458 02 Oct 2015 @ 1120 02 Oct 2015 @ 1325 MAB The Pit overflowing, Jetsam completely empty. Water in White vent good at times. Runoff from Black Growler is slight and channel turning green. Slight green around the outside base of White vent
2439 29 Sep 2015 @ 0913 29 Sep 2015 @ 0925 billwarnock No Ledge eruption and situation the same: No water from Red Vent; sporadic water and steady steam from White; Pit still overflowing and Jetsam more than 3/4 full now. Appears to be back in sleep mode.
2432 27 Sep 2015 @ 1650 27 Sep 2015 @ 1800 MAB 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.
2419 25 Sep 2015 @ 1720 25 Sep 2015 @ 1740 billwarnock 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. Rangers said MA was there for Whirligig around 1700, but she didn't answer radio call. She may have more to report.
2409 23 Sep 2015 @ 0900 23 Sep 2015 @ 1200 billwarnock Now into day 11...NO water in Red with light steam, very light water and steady steam from White; Pit full and overflowing; Jetsam 3/4 full--practically no splashing in shoulder vents, I went off to check other features before coming back before noon. It looks as if it MAY have finished its series.
2404 22 Sep 2015 @ 1940 --- MAB 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!
2400 21 Sep 2015 @ 0930 21 Sep 2015 @ 1748 MAB 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
2393 20 Sep 2015 @ 1900 --- ypcaribou White vent wet on arrival at 1845 but no splashes. By 1900 it was having short (in height) 3 second bursts every 7 to 12 seconds. Red vent had gentle wisps of steam but no water. Pit full but not overflowing. Jetsam low but shoulder vents splashing.
2382 19 Sep 2015 @ 0645 --- Barbara Lasseter No visible water in any vent. Pit is 1/2 mudflat. Steam not very forceful in white vent, very gentle wafting from red vent. Jetsam very low.
2375 18 Sep 2015 @ 1730 --- MAB Day Six: No water in White or Red observed all day. Steam ranged from gentle to periodic louder forced steam from both. The Pit is full but not overflowing. Active Jetsam shoulder vents had noisy water sounds though, it wasn't completely devoid of activity.
2371 17 Sep 2015 @ 1103 17 Sep 2015 @ 1403 LotusBaker white & red breathing with no water when we arrived pit looked full at 2 red only breathing with no water pit still full rangers had no record of any thing since the 12th
2354 15 Sep 2015 @ 1758 --- MAB Day Three - water had returned to Black Growler. No spritzing from White or Red vents, and formation wetness and pool levels not applicable due to heavy rains. I cannot go again until Day 6.
2339 13 Sep 2015 @ 1000 --- Jake still steam phasing.
2336 12 Sep 2015 @ 0821 --- Kitt B ? - mixing with steam at 0818? Do you mean 0918?
2327 12 Sep 2015 @ 0810 --- Graham Pit almost full, no beach exposed but it's below overflow, maybe an inch or two. Lots of water from White. Lots of smoke. Could not see Red
2321 11 Sep 2015 @ 1830 --- MAB Water returned to the system between 1030-1230, from completely dry to a moist White vent and beginning to slowly fill the Pit. When I left at 1830, the Pit water level had risen to about 2 feet from the rolled log sign, or about 18" below the rim on the south side.
2319 11 Sep 2015 @ 1430 --- Graham Pit still very low. White continuous steam with water 50%of the time. Red having small splashes 2 to 4 min apart. Better than yesterday but still not ready.
2316 10 Sep 2015 @ 1240 --- Graham Pit very low. Frequent steam huffs from White and Red vents but no water.
2276 06 Sep 2015 @ 1515 --- Tara 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.
2273 06 Sep 2015 @ 0815 --- RMichaels Water in pit noticeably higher even since 0600 (but still below overflow). Good water from white vent and some splashes from red. Jetsam appears to be rising.
2271 06 Sep 2015 @ 0600 --- RMichaels Pit has come up significantly since last night (now about 1 foot from overflow). Consistent water from white vent. Jetsam still low.
2268 05 Sep 2015 @ 1100 --- Graham Pit very low, water divided in 2 pool's. White light steam. Jetsum way down.
2259 04 Sep 2015 @ 1000 04 Sep 2015 @ 1725 MAB 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.
