37899 31 Oct 2024 @ 1655 --- SantaFe108 Huffing steam. Runoff channel almost entirely covered with snow at Steerage.
37846 29 Oct 2024 @ 1741 --- MAB below lower deck the little rectangular pool in the channel butted up against the formation is full 'erupting' with cute little blurps coming out on the SB side - clear water over gray sands but a green rectangular patch on the floor which might be the previous water level?
37827 29 Oct 2024 @ 1310 --- MAB steamy - possible light spritzes audible not visible
37786 27 Oct 2024 @ 0851 --- MAB N vent pushing steam more than SV but it joined in - possible spritzes - flir shows heat a little way down the channel
37745 24 Oct 2024 @ 1538 --- DanS Huffing steam. No water has returned to system yet.
37573 14 Oct 2024 @ 1100 --- cb SB is gently steaming and channels dry. **Cistern Spring really has not changed water level since last night's observation. still ~5' below the inner rim and still has the occational softball sized bubble breaking the surface. **@ 1830 Cistern Spring water level and bubbles are unchanged from 1100 post.
37556 13 Oct 2024 @ 1800 --- cb 6D9.5H PE, Done! SB is gently billowing steam. channels dry. ** Cistern Spring water level is ~5' below the inner rim. pool is clear, and I saw a few (3)bubbles break the surface in my brief visit. It has a wee bit of steam. **Emerald Spring pool is high, in overflow, and is clear & calm.
37535 12 Oct 2024 @ 1715 --- cb 5D9H ie, SB is starting its slow down with only vigorous huffing steam this evening. NV has a very thin veil of water in the steam. SV is all steam & its channel is 95%dry except for a thin area of moisture down the channel. ** Cistern Spring has dropped about another 1.5' below yesterday's level. ~2.5-3' below the inner rim. pool still has a weak boil with bubbles 🫧 breaking the surface in a variety of areas over the vent. (more bubbles 🫧 than yesterday) Pool is greenish in color. **Emerald Spring is more turquoise than greenish today. the pool is clear, calm & overflowing.
37522 11 Oct 2024 @ 1735 --- cb 4D9H. SB is STILL ie and both vents are still constantly and concertedly throwing vertical water + bounces! NV to 30+' and SV 10+'. SV has a steady stream of water down the channel. ** Cistern Spring water level is about 1.5' below the rim of the inner tube, clear and still has some bubbling that's breaking the surface over the vent. **Emerald Spring is high, overflowing, calm.
37515 10 Oct 2024 @ 1630 10 Oct 2024 @ 1730 cb 3D8H still ie. Both vents are still active, having concerted vertical play, tho not as tall as yesterday and more mix of steam and water with the occational bounce. NV ~20+' & SV ~8'. SV. Little bit of water running down the SV channel. **Cistern Spring down to about a foot above the inner rim. pool is clear, greenish with a weak bubble 🫧 breaking the surface over the vent. ** Emerald Spring pool is high, overflowing, clear, greenish & calm.
37471 10 Oct 2024 @ 1002 --- SantaFe108 Near steady steamy spray from both vents, enough water in it to put down babbling brook.
37464 09 Oct 2024 @ 1720 09 Oct 2024 @ 1750 bbev NV continuous jetting and vertical to 45+'. SV continuous wide vertical up to 15-20'. Concerted eruption with simultaneous increase and decrease in volume and height. very little runoff in either channel. Visitor reported seeing it erupting at 1645. CS down 24" below rim of pool. Steamboat says goodbye to us one more time!
37453 09 Oct 2024 @ 0825 --- bbev Another treacherous skate down to SB. Tall vertical steam cloud with light precipitation from the bench down past Cistern, forming a solid sheet of ice. No liquid water seen other than steady light flow down SV channel. Cistern 18-20" below edge, clear, no steam, occasional bubble over vent.
37440 08 Oct 2024 @ 0805 --- bbev Skated down to SB on a thick sheet of ice! No water, only steam visible out of NV. Trickle of water down SV channel but did not see any liquid water coming out of the vent, Very steamy and cold this morning. CS is down only 13-15", little steam, occasional bubble over the vent.
37425 06 Oct 2024 @ 0915 06 Oct 2024 @ 1741 Ben VL Stronger minors at 1111, 1420, & 1703. 1111 by far the best of the day; nicely sustained vertical from both vents, raging river (on the smaller side). Overall not as good as what I saw last week, and SV is still dragging behind NV. Play in between events merely ok. NV fairly thick and happy with a lot of bounce & brief vertical. SV poor. No sustain, vertical, or heavy runoff unless NV is making it. Shoulder dry. CS still low.
37385 03 Oct 2024 @ 1550 --- SantaFe108 Quick 15min pitstop. NV mostly angled with some tries to go verticle + a little bounce, but all small stuff. SV just hucking angled spray for the most part. One short minor with NV verticle + bounce w/ SV being slightly thicker put down a babbling brook.
37263 29 Sep 2024 @ 1630 29 Sep 2024 @ 1720 User34 North is indeed having frequent vertical and bounce, however all but a small handful of those were meaningless fleeting spritzes and sloshes. A series of three minors just past 1700 had more sustained and heavy North play, both angled and bouncing, with mediocre South play trying to go vertical. The first two of these minors sent strong babbling brooks down the runoff channel, but according to Bill Beverly not enough to go into the east channel under the bridge, which was damp.
37269 29 Sep 2024 @ 0905 29 Sep 2024 @ 1505 Ben VL NV boomy in the morning but quieted down by the afternoon. NV has some pretty nice volume, and frequent small bounce/vertical. SV dragging along behind, but willing to engage with the bigger NV's. ~0945 conc, sust, vertical with raging river. A bit hard to see SV but NVV hit about 30'. ~0955 smaller followup. ~1006 another even smaller followup. 1200 isolated concerted sustained vertical w/ river. 1244 nice concerted sustained vertical, NV punchy and heavy, SV nice sustained fountaining to end it. Didn't get me to stand up or anything though. 1253 followup, not sustained but almost as thick and tall. 1312 somewhat tall NVV pop. (More NVV than that seen, just what I took notes of). Regressed after that, a lot of quiet periods, jabba was drying out almost completely, all minors just single splashes. Decided to leave by 1500. ES clear, calm. CS still very low. Echinus clear.
37241 29 Sep 2024 @ 0846 --- TSBryan very steamy but one so-so concerted burst otherwise relatively minor jetting mostly from North
37214 28 Sep 2024 @ 1525 --- cb Similar to yesterday. NV mix of angled and vertical play with the occational nice bounce. Many are concerted but SV is lacking oomph (mostly just spitting, angled play. lacks verticality) Several weak babbling brooks. SV channel is starting to lighten ~20' below its vent. NV channel has small standing pools of milky/muddy water in front of middle deck. 3 active, noisy mud pots scattered on the platform. Back shoulder and far back channel are bone dry. 1625 nice concerted play that put a nice river of water down SV channel to Steerage. channel has streaks of white in the channel.
37193 27 Sep 2024 @ 1800 --- cb Improved play from last evenings observation. more continuous & concerted play from both vents. SV channel has a nice flow of water and I observed a few solo SV that were angled but had more volume than yesterday. 2 babbling brooks during my observation. NV play also has increased volume & height with bounces. back shoulder is still dry. NV run off channel & the channel below the upper deck both have water. The upper deck channel has a fun active bubbler. Much improved!
37175 26 Sep 2024 @ 1711 --- cb kinda shocked at how disappointing the SV channel looks. dry patches especially at the top of the channel and dry patches scattered down the sv channel with BARELY a trickle of water down the SV channel. Back shoulder dry. NV having mix of angled jets (~30') & bounces, SV weak, angled spray. ** The new bridges over the NV & SV runoff channels and the new bw from Cistern Spring to Steerage (SV bridge) are finished and are AWESOME! They are elevated and no longer bounce! GREAT JOB! Bummer is, the tree at Steerage is gone...
37157 25 Sep 2024 @ 1500 25 Sep 2024 @ 1620 Dan A Very north dominant today, strong north with verticals up to 40’, however none of the verticals sustained, and South was fairly weak it had occasional brief unsustained vertical in conjunction with north vertical, some strong babbling brooks seen but that’s it. Bob jones was observing earlier in the day and noted the same behavior.
37121 22 Sep 2024 @ 1400 22 Sep 2024 @ 1900 Dan A Steamboat improved from last week’s observations, lots of vertical bounces, north was very boomy sounding as well, 1710 nice concerted vertical minor with tall fountaining south that put down a raging river, None of the vertical minors that I observed sustained for long and there was no sizable follow up to any of them.
37095 20 Sep 2024 @ 1600 20 Sep 2024 @ 1620 Micah Kipple In the 20 minutes I watched, Some Concerted minors with a handful of vertical shots from North Vent. South Vent got voluminus enough to send a *trickle* down the runoff exactly 3 times. Overall activity is weak.
37096 20 Sep 2024 @ 1516 20 Sep 2024 @ 1537 htm weaker angled jetting than 9/16 and 9/17. no babbling brook duals
37065 19 Sep 2024 @ 1230 --- cb we saw nothing exciting in our brief observation. NV angled, SV angled, both have weak activity. SV runoff channel had a trickle of water down the center but really looked on the dry side. The boardwalk/MCC crew is making great headway on elevating and replacing the Steerage bridge and bw from Cistern toward Echinus.
37032 17 Sep 2024 @ 1634 17 Sep 2024 @ 1654 htm Similar to yesterday. Weak angled jetting from NV and SV, one dual slightly stronger than what I saw yesterday.
37018 16 Sep 2024 @ 1845 16 Sep 2024 @ 1910 htm weak angled minors from NV and SV, a couple concerted NV/SV with some runoff from SV, no appreciable runoff from NV; no change when I left the basin at 20:45
36980 14 Sep 2024 @ 1400 14 Sep 2024 @ 1500 rwd03 Very weak stuff, big disimprovement from last week. Didn't see anything sustained for impressive. Temperature graph also shows a slight decline over last few days. :(
36889 10 Sep 2024 @ 1558 --- cb stopped twice on my way out and back from Vixen. Sporadic play from both vents. mostly angled with a few NV bounces and vertical play. SV played a bit but is weak and at 1600 has dry patches with no trickle of water. disimprovement!
36874 09 Sep 2024 @ 1345 09 Sep 2024 @ 1646 Ben VL Took until I stepped on the platform to hear any noise out of it on the way in. Long quiet periods, NV not very grumbly. Most minors are brief. SV channel drying out in spots sometimes. NV has a bit of volume, and frequent bounce. SV fairly wispy, and dragging behind NV. Occasional large bounce or somewhat sustained angled SV. 1400 concerted vertical with both vents sustained for a few seconds, but the runoff was a lot less than I anticipated. Small followup 1408. Some babbling brooks seen, and a couple other concerted minors with vertical.
36877 09 Sep 2024 @ 0755 09 Sep 2024 @ 0840 Suzanne Activity was similar to what I observed yesterday, with a couple of small vertical bounces from North Vent and wispy South Vent. No minors produced any significant runoff during this observation period.
36844 08 Sep 2024 @ 0840 08 Sep 2024 @ 1115 Suzanne Small improvement from the past few days with a few small vertical bounces from North Vent. Long pauses between minors. South Vent still wimpy. One decent minor with fountaining from South Vent at 0942. Produced a noisy babbling brook. No followup.
36834 07 Sep 2024 @ 1800 --- Kyle similar to this morning if not worse. observed from 1700-1800. Range function on GT Android is not working
36829 07 Sep 2024 @ 1130 --- ge North vent medium sideways, south small with a few medium splashes. Nothing near vertical. Weak water from north side, steady small flow from south. Several "you can do it" moments, but no follow up. Left at 13:16
36822 07 Sep 2024 @ 0830 07 Sep 2024 @ 0930 Suzanne No change from yesterday. North Vent angled and weak, very little activity from South Vent.
36833 07 Sep 2024 @ 0745 --- Kyle SB is not really doing jack. occasional weak angled NV jetting. almost nothing from SV , barely enough output to maintain a slow drool down the channel. nothing vertical, nothing concerted nothing sustained. observation period 0745-0855. Range function on GT Android is in fail mode
36809 06 Sep 2024 @ 1445 --- cb Really just putting a note in to say the bw crew is making great progress on the bridge at steerage! (over the SV runoff channel) otherwise nothing worth noting happened in my 45m observation. back shoulder & channel dry. patches of the sv channel are dry as is the base of Jabba
36794 06 Sep 2024 @ 0815 06 Sep 2024 @ 1015 Suzanne North Vent angled and weak, wispy spurts out of South Vent. No significant minors seen.
36778 05 Sep 2024 @ 0845 05 Sep 2024 @ 1415 Suzanne Moderate improvement in activity from the past 2 days. 0845 to 1045: 1 decent minor per hour with runoff from South Vent (no fountaining), nothing sustained. 1122 to 1134: activity increased with a series of minors, initiated by North Vent, nothing very high, but vertical, and South Vent joined in to produce decent runoff. 5 total noteworthy minors in 12 minutes. Then very little until a nice minor with some fountaining from South Vent at 1200, with a smaller followup minor at 1203. Then very little activity until 1325 when I observed the best minor of the day: thick North Vent vertical and nice tall fountaining from South Vent. Produced very noisy babbling brook runoff. Unfortunately there was no followup. One more decent minor observed at 1400, but it was weaker than the others.
36748 04 Sep 2024 @ 1223 --- CraigC 1223 good sustained South 1355 concerted, good sustain from South
36745 04 Sep 2024 @ 0915 04 Sep 2024 @ 1200 Suzanne Activity worse than yesterday. North Vent behavior very similar with occasional small vertical bounces. South Vent weak. 1 somewhat decent minor seen during the time I was there: where South Vent produced a bit of noisy runoff. Nothing sustained.
36726 03 Sep 2024 @ 1600 03 Sep 2024 @ 1700 cb Ditto on Suzanne's report! NV some activity that included a few bounces, and 2 reverse jets but mostly angled play that were short in height. SV had little activity during this time. SV channel is still brown with a trickle of water. *FYI Boardwalk crew has removed the bridge at steerage and bw is closed from Cistern to Echinus.
36723 03 Sep 2024 @ 0853 03 Sep 2024 @ 1210 Suzanne Many short periods of quiet between minors, mostly angled from north Vent with South Vent not wanting to participate. I observed 4 somewhat decent minors the entire time I was there: North Vent was vertical but not tall, and South Vent participated enough to produce noisy runoff. None of the minors were sustained or had any follow up.
36685 01 Sep 2024 @ 0900 01 Sep 2024 @ 1600 Dan A Activity better today than last two days, but nothing huge, logger in south runoff channel was buried under 1-2 inches of debris, debris has been removed so if the logger is showing higher baseline temps tomorrow that’s likely why.
36649 30 Aug 2024 @ 0900 30 Aug 2024 @ 1300 Dan A Weak activity from both vents, hardly any runoff from south seen.
36579 27 Aug 2024 @ 1831 --- cb brief observation. weak angled jetting. SV channel has a thin trickle of water. back shoulder and channel bone dry. Jabba mostly dry. at steerage evidence suggests some nice activity before I got here. channels with water
36574 27 Aug 2024 @ 0815 27 Aug 2024 @ 1045 Dan A Very Occasional nice vertical minor with raging river, neither North nor south would sustain vertical for long. The minors in between these events fairly weak with south vent channel drying out pretty significantly at times.
36527 24 Aug 2024 @ 0700 24 Aug 2024 @ 0745 Dan A Weak activity during this observation time, north wispy, very weak runoff from south.
36445 18 Aug 2024 @ 1122 --- Craigmon99 1122 Holy cow minor. I stood up and started yelling. North and south combined into a wall of water. Raging River. Sustained wall of water for 6 seconds. South thick. 1138 same massive wall of water. More sustained and a follow up large minor Disimproving around 1200 Steamboat area is consistently rumbling.
36339 09 Aug 2024 @ 1830 09 Aug 2024 @ 1900 cb Both vents mostly angled jetting with two 3' bounces. SV channel is wet & I saw 1 weak river. kinda typical recovery play.
36180 30 Jul 2024 @ 1648 --- cb water has returned to the system, but platform still bone dry. weak activity.
36169 29 Jul 2024 @ 1636 --- cb gently steaming. platform dry. **Cistern Spring pool is ~1" below the scalloped edges and only overflowing out the established channel. Medium 2 point boil. pool clear. **Emerald Spring is crystal clear, pool lower than I've seen but still overflowing. Green, calm & clear.
36112 26 Jul 2024 @ 0937 --- cb ~10D18H PE. no change. Billowing steam. Platform dry, no sounds coming from the mud feature in the confluence of NV channel. **Cistern Spring is in overflow but only out the established channel toward Echinus. (prolly reached overflow yesterday afternoon) pool is low, blue in color, cloudy with a weak boil. pool level is ~1" below the rim with scalloped edges exposed. ** Emerald Spring - no change. pool is greenish blue, overflowing, clear, calm
36071 24 Jul 2024 @ 0913 --- cb no water in the system yet. billowing steam. channels dry. **Cistern Spring water level is at the top of the inner tube rim. Vigorous blooping boil and water is clear and steamy.
36050 23 Jul 2024 @ 0955 --- cb Platform is calm, slight billowing steam, no water from either vent. channels dry. **Cistern Spring - water is at the bottom of the crater.  I can hear it churning, but water is not visible yet. Very steamy. **Emerald Spring is very steamy for a warm summer morning! clear, greenish blue, calm, and in overflow
36006 20 Jul 2024 @ 1952 --- cb platform is very quiet. Both vents are gently steaming. The mud pot at the confluence of the NV channel has a audible bubble but no water or mud observed. ** Emerald Spring Pool is very high, overflowing, clear, greenish blue with just a few random bubbles breaking the surface. **Cistern Spring is bone dry. no steam, no audible sounds, no water.
35982 19 Jul 2024 @ 0838 --- cb SB platform is gently steaming with occational huffs of steam. NV channel has a thin trickle of water coming from fissures in the upper channel. **Cistern Spring is completely empty>no sounds, no water, no steam! prolly drained overnight. **Emerald Spring is very steamy this morning but looks clear, green, calm & in overflow
35938 17 Jul 2024 @ 1154 --- bbev 45hrs PSBE: Mixed spray of water and steam from NV, enough to put a trickle of run off down SV channel. CS down 18-20", still well above rim of inner tube. Clear with occasional bubble.
35912 16 Jul 2024 @ 0805 --- mhreed ~17h post eruption. Still in steam, no jetting. CO2 monitor at the middle platform reads 512ppm.
35891 14 Jul 2024 @ 0857 --- PamM NV lots of angled water SV little water But runoff 20 minutes observed
35880 13 Jul 2024 @ 1844 --- cb Meh! Tall Angled play with a few bounces from NV. SV angled & channel has a few dry patches with a weak trickle of water. Back shoulder and back channel dry.
35844 11 Jul 2024 @ 1619 11 Jul 2024 @ 1911 bbev Nice, tall, broad, concerted, sustained minors at 1644 and again at 1744. NV mostly active in between. Back shoulder bone dry. Far back channel dry. Barely a trickle in NV runoff. SV runoff drying up between good minors. 1825 CVS. 1848 CVS.
35791 08 Jul 2024 @ 2023 --- Polly The temperature graph finally refreshed today after being down for three days. You can clearly see the low part of the cycle the last couple of days.
35790 08 Jul 2024 @ 1124 08 Jul 2024 @ 1424 Polly Improved from yesterday: I got 82% concerted the first hour. During the hour I recorded 8 babbling brooks and 2 raging rivers. There was a nice series as I started this first hour, but it was not as strong as I saw 3 days ago. The next hour started off very quiet, until 1322, when North Vent had the tallest minor that I’ve seen recently. For the most part, the second hour was quieter than the first, except for that tall north. The third was a little better than the second, but not enough to make me want to stay. Overall, North Vent has often been “boomy” & grumbly.
35780 08 Jul 2024 @ 0715 08 Jul 2024 @ 1100 Ben VL Polly arrived just as I was leaving. A little quiet at the beginning. Picked up around 10 or so. Decent Conc. Sust. Verticals at 1008 & 1037. Neither of them particularly amazing but the best of the sit. Bounce every now and then. A couple smaller events but mostly unimpressive otherwise. Most minors are brief splashes. NV has reasonable height, SV only interesting when NV is also interesting. ES ever so slightly cloudy.
35770 07 Jul 2024 @ 1600 --- Polly Steamboat still seems to be recovering from its normal slowdown in its cycle. It was hard to observe, especially this morning, due to north and northeast winds blowing the steam towards me. Most minors that I observed this morning (0805-0905) were small in size and volume. This afternoon (1455-1555) some minors were larger than this morning’s. There were few quiet periods this afternoon. The runoff channel seems to still be getting lighter.
35733 05 Jul 2024 @ 1320 05 Jul 2024 @ 1700 Polly Dan reported a nice minor before I arrived. For the first hour, I recorded about 79% concerted. Then, from 1400-1500, it was about 80%. During the whole observation time, there were nice wide minors at times, but other periods of only splashing and long pauses between minors. There was one minor that I recorded as North center & South Vent “fountaining” to about tree height (shorter trees from my seated position on the mid deck). I recorded 5 Raging Rivers, & 10+ Babbling Brooks. The South Vent runoff channel is starting to whiten. The last 2-3 hours were much quieter than earlier in the day, with minors having shorter durations and less water.
35721 04 Jul 2024 @ 1125 04 Jul 2024 @ 1600 Polly Overall, there were some nice minors with good runoff at times. There were also longer quiet periods as the day went on. Many of the minors were of short duration. Concerted minor with vertical north and a raging river started the first hour. There were 2 more babbling brooks, and another nice minor with a raging river about 50 minutes into the hour. Another 2 babbling brooks rounded out the hour. The minors during this hour were about 87% concerted. At 1305 there was another nice minor with strong runoff followed by some babbling brooks and another nice minor at 1359. Two more came at 1439 & 1441. The minors slowed as the afternoon went on. The runoff channel was drying out between minors, which were spaced further apart as time went on.
35705 03 Jul 2024 @ 1444 03 Jul 2024 @ 1600 Polly Wind and steam at times made it difficult to tell for sure if South joined in at the start of some minors, but overall they appeared to be about 76% concerted during the first hour. Steamboat was having a series of minors with tall Norths and some vertical about once an hour. There were at least 6 babbling brooks plus 8 more that were audible.
35681 02 Jul 2024 @ 1636 --- cb brief visit. 1 attempt at some verticality from NV to about 15' that ended in a reverse bounce/jetting. SV is just randomly spitting water as seen in my brief observation. SV runoff channel is wet with a fairly consistent drizzle of water at steerage
35679 02 Jul 2024 @ 0854 02 Jul 2024 @ 0954 Polly A bit steamy with wind blowing minors toward the south, but appeared to be about 70% concerted. North Vent was tall at times with some vertical. South Vent was quieter (generally more splashy but not very tall) and did not appear to initiate any minors. There was audible runoff a few times.
35669 01 Jul 2024 @ 1632 --- CraigC 1632 impressive concerted vertical minor with good runoff
35649 30 Jun 2024 @ 0900 30 Jun 2024 @ 1100 Dan A During this observation time I observed many sustained north vertical minors. Most of the vertical minors weren’t tall, however at around 1050 from steerage I saw a big sustained concerted north/south minor that sent many fist sized rocks down the channel. Several raging rivers were also observed in this two hour time period. The play in between these big events is very lackluster with hardly any runoff down the channel, the channel was actually drying out substantially in between these big minors
35446 22 Jun 2024 @ 1400 --- K.Cooper Mostly lackluster - Angled NV and SV concerted every few minutes, wispy. Some minors putting a small amount of water down the channel. 1415 had one concerted with short lived vertical in both N and S, only vertical during observation
35294 17 Jun 2024 @ 0955 17 Jun 2024 @ 1055 Dan A 1017 series of thick and tall angled north vents with sustained low vertical and south putting down a babbling brook, 1047 another series of thick north with vertical this time not sustained, play in between these events were pretty lackluster north mostly on the wispy side, south only occasionally putting down the channel.
35259 16 Jun 2024 @ 1940 --- User34 A little bounce from North seen in my short observation that gave a modest babbling brook runoff
35258 16 Jun 2024 @ 1350 16 Jun 2024 @ 1414 Geyser Guy700 North Vent minors around every 20-45 seconds. Slanted 45 degrees. concert minors with North Vent lasting longer. Occasional South Vent play. Runoff consistently but just enough to keep the rock wet
35149 12 Jun 2024 @ 1343 --- CrisG mostly gentle steam. occasional typical minors from north vent and 2 weak spashes from south in 15 min observation period. no water at steerage
35105 10 Jun 2024 @ 1423 --- SantaFe108 Gently forcing steam, with occasional wispy huck from SV.
35059 10 Jun 2024 @ 0936 --- Graham Mostly gentle steam from North Vent. Splashes from North Vent 0938, 0942. Trickle of water at steerage.
34994 08 Jun 2024 @ 1046 --- cb Dry, mildly grumbly, VERY Occational NV spits according to ranger Chris.
34810 01 Jun 2024 @ 1307 --- bbev Quietly steaming from both vents, no water. CS Drained completely. No steam, no sound coming from crater!
34803 01 Jun 2024 @ 1037 --- ge Putting out light, steady steam.
34792 31 May 2024 @ 0800 31 May 2024 @ 1600 ypcaribou Returned to water from steam (8am is a placeholder until I get actual time). Continued angled jetting 60 to 80 feet from N vent and maybe 5 to 10 ft from S vent all day. Still jetting at 4 pm when he left basin. Cistern water level is inside pool but above inner tube as of noonish.
34775 30 May 2024 @ 1647 --- bbev 15hrs PSBE: Moderately audible steam from both vents, no water in either runoff channel. CS is ~1' below overflow, clear and flat with an occasional bubble over its vent.
34759 29 May 2024 @ 0800 29 May 2024 @ 2057 Ben VL 0914 strong concerted sustained vertical, 0915 bigger followup. Two more SCV's @ 0923 & 0924 (tall nv vertical). Followup was better today, and NV not dragging behind SV as much. Declined sharply after the 0900 events. Occasional sustained concerted verticals throughout the day but nothing as strong as in the morning. Play in between weaker too. NV less rumbly in the evening and SV runoff seemed less.
34739 28 May 2024 @ 0730 28 May 2024 @ 2231 Ben VL Better than yesterday. A lot of nice minors but not a lot of follow up or sustain to them. SV often finishes them off with a long solo after NV drops out. Emerald still clear & Cistern still only out the back channel. Fairly slow until late morning. 1059 CSV with tall NV vertical. Decent or better concerted verticals @ 1216, 1300, 1342, 1358 & 1359, 1412. 1441 with NV a bit more sustained. 1527 very large concerted vertical w/ tall NVV and sustained thick south solo at the end. Best minor of the last couple days so far. 1655 CSV. 1836 large again, not quite as big as 3h ago. 1855 very large again. More conc. sust. 1953 & 2041. 2056 thick. 2218 heard something loud from the parking lot.
34719 27 May 2024 @ 0700 27 May 2024 @ 2158 Ben VL Fairly quiet most of the morning. Occasional strong concerted minors in the afternoon and evening. Not quite as strong as what we got yesterday evening. SV can have some nice sustained fountaining, & NV can have some nice vertical but it is usually brief. There is some follow up but it is usually much smaller. NV very grumbly. Cistern still only overflowing out the back channel. Emerald clear. Echinus was murky this am but is now clear.
34714 26 May 2024 @ 1600 26 May 2024 @ 2120 Dan A 1921 concerted vertical minor, 1924 concerted vertical minor, 1925 another concerted vertical minor, 2040 concerted vertical minor with a very nice south vent.
34705 26 May 2024 @ 0919 26 May 2024 @ 1000 ypcaribou 0919 at steerage... runoff steady but not very exciting. 0939 from lower deck... concerted, sustained, but angled surges. Mixed with random tossing in between. One angled N did get to tree tops. Surges made me look up but not stand up. There was no screaming from the gazer encampment. They all continued reading their books. :)
34694 26 May 2024 @ 0716 --- ypcaribou Trickle in N channel, surge of water down S at 0721. Bigger surge at 0723 was almost raging level. Splashed up and over large gravels. Spouting out of both vents with S initiating. Didn't stay long.
34677 25 May 2024 @ 1510 25 May 2024 @ 1734 Art 1530-1550 - Series of concerted minors with continuity to the play 1620- Strong concerned vertical minor 1638 - strong long duration wall of water minor 1641 - Continued Follow up 1650-1730 - Lots of strong minor activity but not like the sustained events at 1530 and 1620
34675 25 May 2024 @ 0659 --- CraigC 0659 CV good sustain on South, large runoff.
34662 24 May 2024 @ 1200 24 May 2024 @ 1500 Dan A Steamboat a tad better than earlier today, north thicker, south more consistent runoff, a couple strong babbling brooks, mostly angled play except for some brief vertical bounce.
34659 24 May 2024 @ 1015 24 May 2024 @ 1145 Art No change from Mara’s notes this morning.
34654 24 May 2024 @ 0915 24 May 2024 @ 1000 Dan A Steamboat has improved just a little bit from past couple days, north consistently thicker south more frequent, there was no vertical anything seen not even a bounce, south runoff is still weak no big runoffs seen.
34655 24 May 2024 @ 0710 24 May 2024 @ 0940 mhreed Arrived to lethargic but coordinated play that steadily improved. Had a series of minors that were short in height but high in volume, 3-10 minutes apart. South Vent put out a lot of sustained water during these events. Mostly quieted down again by 0930.
34633 21 May 2024 @ 0654 --- CraigC 0654 Concerted vertical minor with some sustain and good runoff. 0747 Real nice concerted vertical minor with decent sustain and high runoff. 0948 Huge concerted vertical minor with good sustain and very impressive runoff. 1027 Cv with sustain 1030 followup cv 1053 Massive cv with lengthy sustain with huge runoff.
