35561 25 Jun 2024 @ 1709 --- K.Cooper Frying pan hole NW of Scissors spring deeper - both vents now pooling water about a foot below the surface. Splashing consistently to the surface. Still getting stronger
35536 24 Jun 2024 @ 1930 --- Craigmon99 Thumb Geyser - boiling semi vigorously from thumb part
35535 24 Jun 2024 @ 1917 --- Craigmon99 Feature in front of surging spring and next to boardwalk has been boiling vigorously all day. Murky light brown water. Smells of dead bacteria
35531 24 Jun 2024 @ 1826 --- Craigmon99 Percolating Spring has been bursting up to 2 feet high all day
35510 24 Jun 2024 @ 0706 --- Craigmon99 Blue Funnel Pool Water to lowest inner tube. Semi-vigorous bubbling from back vent
35505 24 Jun 2024 @ 0645 --- K.Cooper unng frying pan NW of Copper Kettle continues to deepen: now blooping 3in boils
35475 23 Jun 2024 @ 1604 --- Craigmon99 Newly active frying pan on other side of boardwalk of scissors spring has deepened substantially and is pooling water at the bottom with occasional spritzing
35449 22 Jun 2024 @ 1613 --- Craigmon99 Gurgling heard and water seen from 2 features on the other side of the boardwalk as economic.
35399 21 Jun 2024 @ 0835 --- K.Cooper Frying pan hole on the right side of the bw about 90% of the way walking from Copper Kettle to Scissors spring continues to frying pan - saw a jet of water above the surface that chipped off some of the bridge
35209 14 Jun 2024 @ 1555 14 Jun 2024 @ 1559 Geyser Guy700 Clearwater Springs: Gently roiling on most springs. Small sizzling basin can be heard from road.
35226 14 Jun 2024 @ 1524 --- JSJ Pair Geyser (= RCN database name) in the southwestern Kaleidoscope Group (Lower Geyser Basin); vent is located at 44° 33' 15.35" North latitude, 110° 48' 48.74" West longitude. Blipping at 1524. Think I saw other minor activity this afternoon as well (Clepsydra steam was often obscuring).
35183 13 Jun 2024 @ 1722 --- K.Cooper Have not seen unng between Borah peak and dragon "Little hucker" over the past few Beehive waits
35068 10 Jun 2024 @ 0920 10 Jun 2024 @ 1212 SantaFe108 "Tree Island Geyser" was not in eruption during any point in my sit.
35073 10 Jun 2024 @ 0929 --- SantaFe108 Lava Pool spouter is active with full water. Small spring beyond Swiss Cheese Pool in Primrose Springs is erupting to ~1 ft.
34935 06 Jun 2024 @ 1913 06 Jun 2024 @ 2040 SantaFe108 Compiling all my observations here. UNNG between Dragon and Borah Peak "Little Hucker" at: 1913, duration: ~30s, height: 2ft 1924, duration: 33s, height: 2ft 1935, duration: 29s, height: ≥1.5ft 1946, duration: 32s, height: 2.5ft 1958, duration: 34s, height: 3ft 2008, duration: 28s, height: 3ft 2018, duration: 27s, height: 2.5ft 2028, duration: 33s, height: 2.5ft 2040, duration: 32s, height: 3ft Intervals are approx 11m. Abandoned 2040.
34937 06 Jun 2024 @ 1955 --- JarnoO Some information regarding Little Hucker (UNNG between Borah Peak and Dragon) I can gather from satellite imagery: From Google Earth (imagery date September 2023), it is located at 44.463113°, -110.829763° and shows up as a hole surrounded by a white patch in Dragon's runoff.
Imagery from September 2020 (January 2022 is unusable) shows just a white streak in Dragon's runoff channel and no obvious hole. Imagery from July 2017 is unclear, but doesn't show a hole at this location; there is a hole ±3 meters (±9 feet) N of it. This hole, however, was overrun by Dragon's runoff between July 2017 and September 2020, but, upon closer inspection and contrary to what was stated here earlier, remains recognizable in later imagery.
July 2016's imagery shows the situation before Dragon's runoff relocation clearer, with June 2016 imagery being the clearest. In both cases, there's a dark patch (which might be the same as Little Hucker) south of it, very near the coordinates stated above. August 2015 imagery also shows the hole and the dark patch, as do April 2015, June 2013, August 2010 and July 2010 imagery. Any imagery before that, though, is simply unusable as (commercial/public) satellite technology wasn't advanced enough to provide detailed imagery.
As a side note, the June 2016 imagery is also what's shown on Google Maps, 8 years out of date by now (it even shows Dragon's runoff heading west rather than south!).
34948 06 Jun 2024 @ 1229 06 Jun 2024 @ 1546 JSJ Tonsils Spring in the Tangled Geysers Group (Lower Geyser Basin). 1229: drained (water is out-of-sight). 1239: water visible again. 1246: water higher. 1257: full pool / basin. 1404: water level low, but still visible. 1410: water out-of-sight. 1416: still empty. 1430: water level has risen, but basin is not full yet. 1443: basin appears full again. 1504: water level is lower, but still visible. 1509: water is out-of-sight. 1527: still empty. 1532: water level has risen, but basin is not full yet. 1546: basin appears full.
34940 06 Jun 2024 @ 1126 --- JSJ Twin Butte Vista Spring (White Creek Group, Lower Geyser Basin) - visible low spouting.
34768 30 May 2024 @ 1238 --- Graham Norris feature between SB bridge and Echinus that was erupting last year is cool and inactive.
34750 29 May 2024 @ 0938 --- cb Tree island Geyser in Norris Porcelain basin is not active at this time
34701 26 May 2024 @ 0819 --- ypcaribou Hole in path near BHC has gotten larger. Maybe 6' by 5'. Triangular with one point toward Steamboat. Audible gurgling deep inside.
34628 21 May 2024 @ 0424 --- JarnoO (wc) Large plume appeared in the Grotto - Fan and Mortar region, which also includes GNT and CLC (I guess that makes for a morning stroll...) but excludes Riverside, Grand and Artemisia. The large part of the plume (which spanned from its origin to out of frame near Castle) sustained until about 0450, after which it significantly declined. I think a Grotto start and a Rocket major can be ruled out due to the duration (Grotto start would just be a short burst of steam followed by steady steam, am not aware of a Rocket lasting any longer than 15m, let alone 20). In any case I'm hesitant to put it on a specific remaining candidate, as each one is more unlikely than the other.
34463 05 May 2024 @ 1850 --- SantaFe108 Gibbon Meadows geyser not erupting, and not a lick of steam from its area.
34324 24 Apr 2024 @ 0900 --- DanS Gibbon Meadow Geyser - only a tiny amount of steam this cool morning. Not erupting.
34307 21 Apr 2024 @ 1710 --- SantaFe108 Gibbon Meadows Geyser is steaming but not erupting.
34226 19 Apr 2024 @ 2030 --- SantaFe108 Gibbon Meadows Geyser steaming and not erupting.
34036 15 Feb 2024 @ 1450 --- aferrara East Chinese Spring: Energetically boiling and thumping. Similar force and volume to good Doublet Pool thumps. Boiling 2' @ 1453.
33972 04 Feb 2024 @ 1504 --- aferrara Feature approx across boardwalk from Scissor Spring with standing, boiling water
33955 30 Jan 2024 @ 1147 --- aferrara persistent spring energetically boiling. two new to me small sputs 2' NE of it boiling as well. STRONG fish odor.
29056 22 Oct 2023 @ 1454 --- SantaFe108 Lava Pool's water level is out of sight viewing from Hurricane Vent. Spouter on the N edge forcing steam at variable volume.
29163 22 Oct 2023 @ 1310 --- SantaFe108 A member of the Porcelain Springs NE of Pinwheel and NW of Blue, named "Island Geyser" (sometimes referred to as "Tree Island") powerfully bursting to 25' tall. Around 1430ish water color became light brown and then was clear again by 1500.
28876 19 Oct 2023 @ 1148 --- DanS Black Hermit Caldron- large dark boils on East side of pool.
28828 14 Oct 2023 @ 1427 --- MAB Gibbon Meadows geyser: from a neighbors FB post steam visible but I couldn't see a clear column of water - photo time stamp was 1427
28725 09 Oct 2023 @ 1330 --- cb Norris back basin>Root pool is also VERY high/full! Highest water level I've seen since 2019. Both pools are connected in the narrow section of the feature, color is a milky green & it had a very weak boil over the vents in each pool.
28645 05 Oct 2023 @ 1421 --- cb Nuphar Lake is still incredibly high, lime green and has thermal water flowing into it from features below where the old lunch station used to rest. The seeps from it and into Porcelain basin are not active .
28607 02 Oct 2023 @ 0917 --- JarnoO (wc) Steam began rising from Spatter's (UGB; opposite of Sprinkler, 44°27'52.9"N 110°50'07.9"W based on Google Maps and Geysers of Yellowstone) spot. Might have included water. In any case it's the earliest recorded activity I have from Spatter, though I do want to note that I only skimmed the overnight captures. Cam panned to the Hill a minute later, so I don't know if other activity followed.
28389 21 Sep 2023 @ 1238 21 Sep 2023 @ 1241 Micah Kipple A couple above-ground splashes from the feature to the north of Rusty and borehole Y8.
28372 20 Sep 2023 @ 0919 --- Micah Kipple The feature mentioned in my previous note has now briefly paused before returning to water phase. With energetic bursting 1-4 feet high. There is an interesting lack of chugging like I observed when I first arrived on the constant bench.
28371 20 Sep 2023 @ 0916 --- Micah Kipple A feature that has been erupting with a similar style to Whirligig's rooster tail vent about 50 feet to the right of Pinto from the bench right at the base of the hillside suddenly switched to a loud roaring steam phase at this time.
28301 17 Sep 2023 @ 1223 --- SantaFe108 Gibbon Meadows geyser Not ie, steaming quietly.
28282 16 Sep 2023 @ 1540 --- SantaFe108 Semi-Centenniel Geyser Still a lighter green color as last reported.
28217 11 Sep 2023 @ 1245 11 Sep 2023 @ 1330 CP New Imperial: eruptions from 1 to 6 minutes in duration, with pauses of 20 to 30 seconds between.
28125 08 Sep 2023 @ 1110 --- Graham Halfway Spring on Seven Mile Hole trail is overflowing.
27670 18 Aug 2023 @ 1650 --- bbev Semi-centenial: pool is a splitpea soup green, where normally l have seen it more blackish brown.
27571 13 Aug 2023 @ 1855 --- minissa I think this is the feature Scott calls Old Surprise Spring. It has been erupting every 10-12 minutes during our Fountain sit, but you have to judge more from the steam cloud because from the overlook it's over a small shoulder of land and it looks like the formation is a deep bowl.
27550 12 Aug 2023 @ 1411 --- JSJ LKNN001 (= RCN database designation) in the Kaleidoscope Group, Lower Geyser Basin; = 1B/vent 1B of Wolf & Paperiello, 1989 (Report on the Kaleidoscope & Sprinkler Groups, pp. 2, 7-8); vent is located 7 meters north-northeast of Kaleidoscope Geyser & 9 meters south-southeast of the center of Drain Geyser; UNNG's vent is at 44° 33' 16.05" North latitude, 110° 48' 47.58" West longitude. I suspect this vent is the same as "Kaleidoscope’s Indicator Geyser". Blipping / low spouting.
27548 12 Aug 2023 @ 1345 --- JSJ LKNN002 - unnamed geyser in the Kaleidoscope Group, Lower Geyser Basin. Located southeast of Three Vent Geyser & southwest of Kaleidoscope Geyser. Entire basin is water-filled; orange-floored with a dark green vent area. Receiving runoff from Kaleidoscope Geyser eruptions.
27536 11 Aug 2023 @ 1336 --- JSJ Broken Egg Spring - in light overflow & gently bubbling.
27498 10 Aug 2023 @ 1510 --- minissa Purple Pools: North boiling intermittently 1-2 feet high from what looks like a low pool {binoculars from between Oblong and Giant}; likewise East. South is periodically sending up a wide steam cloud but unable to see any splashing. Just sayin'...
27304 28 Jul 2023 @ 2100 --- SantaFe108 Two vents in the NBK-3 area spouting ~1ft high.
27266 27 Jul 2023 @ 1615 27 Jul 2023 @ 1650 SantaFe108 Snowglobes: No eruptions observed during this time. Snowglobe #1 and #2 have merged to become a single larger pool.
26952 08 Jul 2023 @ 2000 08 Jul 2023 @ 2037 nails Feature erupting to about 1 foot, durations about 1 minute, intervals about 2 minutes. Located on left side ( looking upstream from bridge) of Tantalus Creek just across the little trees from Corporal.
26914 08 Jul 2023 @ 1125 08 Jul 2023 @ 1225 Janet Jones I thought "Waterfall Geyser" at West Thumb was in here - did someone give it a number? 3/4 full of blue, opaque water. Some bubbles rising in it. Also, "Dancing Geyser" continues to be full and blue and overflowing with microbes growing in the overflow channel. Thumb Geyser was half full, blue opaque water with orange microbes around the edges. The UTF behind Thumb Geyser that has been active for quite some time was splashing. And, I'll add in Percolating Spring here as well since it's not yet listed: No water at all - vent is still full of gravel (amazingly so - really wonder what happened there) Oil Slick is also probably not in here - no water, also no water in Ephedra or Perforated. Lakeside Spring had heavier than normal overflow. Bluebell Pool and Seismograph Pool are also still well below overflow.
26880 07 Jul 2023 @ 0833 --- Tara Gibbon Meadows geyser erupting to 5-10'
26807 03 Jul 2023 @ 1114 --- bbev Gibbon meadow feature is off. 1300 off.
26791 02 Jul 2023 @ 0852 --- bbev Gibbon Meadow feature off, no water, little steam 1057, barely erupting, maybe 1-2' from both vents, can only see water with binoculars.
26776 01 Jul 2023 @ 1146 --- bbev Gibbon Meadow spouter. No steam on a warm day and no water to be seen. Have noticed that the activity has been decreasing over the past week. This is first time l have driven by and not seen any water since l first noticed it erupting on June 12.
26629 23 Jun 2023 @ 1130 --- bbev Spouter in Gibbon meadow continues. Play is 3-5 feet at this time. I have observed some slightly stronger play on occasion during my daily trek to Madison from Norris.
26488 20 Jun 2023 @ 0810 20 Jun 2023 @ 0813 aferrara Small crack ~10' SE of Jagged sputtering 1-3" tall.
26473 19 Jun 2023 @ 1712 --- ypcaribou Spouter at far N west end of Gibbon Meadows as seen while driving NB... "Speaking of Gibbon Meadows, that thing is steaming but definitely not throwing water like it was last week."
26481 19 Jun 2023 @ 1400 --- JSJ Small, unnamed feature 22 meters southwest of Jagged Spring (Black Sand Basin, Upper Geyser Basin). Vent is at 44° 27' 43.08" North latitude, 110° 51' 13.93" West longitude. Perpetual spouting - low to very low splashing.
26468 19 Jun 2023 @ 1330 --- bbev Gibbon Mdw. Geyser N of Sylvan Sprg. Very little steam and no water seen in brief, 5 min observation.
26448 18 Jun 2023 @ 1531 --- Graham Mud Volcano Dragons Mouth Spring has cleared the rocks that fell and blocked the entrance. It is now sending nice waves out of its mouth. Not sure when it cleared out?
26393 17 Jun 2023 @ 0806 --- Graham Snow Globe close to the boardwalk appears less active in 5 eruptions observed, splashed weakly in 2 of them. Second snowglobe erupting about 2 feet.
26378 16 Jun 2023 @ 1907 --- Craigmon99 Pool across from CGG-6 looks hotter than when I first arrived.
26385 16 Jun 2023 @ 1613 --- JSJ Small feature in Flood Group, just above the Firehole River's western bank, about 69 meters west-northwest of Flood Geyser, located at 44° 31' 15.65" North latitude, 110° 49' 46.75" West longitude. Slightly intermittent spraying and spritzing from a sublinear vent.
26384 16 Jun 2023 @ 1422 16 Jun 2023 @ 1427 JSJ LKNN001 (RCN database designation) - a geyser in the Kaleidoscope Group (possibly the same feature as "Kaleidoscope's Indicator Geyser"), Lower Geyser Basin; = UNNG 1B/vent 1B of Wolf & Paperiello, 1989 (Report on the Kaleidoscope & Sprinkler Groups, pp. 2, 7-8); vent is located 7 meters north-northeast of Kaleidoscope Geyser & 9 meters south-southeast of the center of Drain Geyser; vent is at 44° 33' 16.05" North latitude, 110° 48' 47.58" West longitude. Occasional low splashing at 1422; frequent low splashing from 1425 to 1427. No actual eruptions seen as in some previous years.
26270 12 Jun 2023 @ 1340 12 Jun 2023 @ 1415 aferrara Watched several eruptions of Snowglobe and friend. Average height on the second vent 2-3 ft, average for Snowglobe less than a foot. Average interval 83 seconds. 2 eruptions got a few drops of water onto the boardwalk
26182 09 Jun 2023 @ 0625 --- Graham Snow Globe and next hole still active like yesterday. Eruption height seems slightly reduced from last night but second vent still getting slightly over 2 feet. Watched 10 eruptions.
26129 07 Jun 2023 @ 1537 07 Jun 2023 @ 1557 aferrara Second vent, west of feature under the doublet pool sign is growing its vent. Added about 1 square inch to the size of its vent in the last 15 minutes. Seems to have water levels connected to the doublet pool sign geyser, but at a cursory glance doesn't seem to relate in terms of eruption start/stop time.

24299 07 Oct 2022 @ 1240 --- Tara Old Bellefontaine, Fountain Group, LGB. Crater empty, first time I have seen this in over 2 months. As of 1315, steam seemed to indicate a rising pool level but it was not.visible yet.

23985 21 Sep 2022 @ 1230 --- CrisG Mammoth update: Grassy Springs flow stops around the near edge of the three way boardwalk intersection. Dryad is dry. Not even a puff of steam. Canary is extending more in the direction of Jupiter Terrace. Water is not filling the old vent. Decent flow down Marble Terrace. New Blue is pretty and flowing into the terraces. A small trickle is reaching the bottom of the hill. Narrow Gauge has great color to the far end. Orange Spring Mound is still flowing well from the end near the road. Prospect Spring still active, though flow much less than on my June visit and not threatening the road. Mound Spring is still flowing well. Palette is flowing well from the pool west of Devil's Thumb. Thankfully the flow is more away from the Thumb. The pool to the east of the Thumb is not overflowing the terrace as much as usual but appears hotter. The overflow is going south and west of that pool rather than over the side and is pooling hotter water. Cleopatra is unchanged.
