19540 13 Sep 2021 @ 1611 --- Graham At least 5 Clepsydra pauses after Fountain. Likely in a stall, did not stay. This morning's "stall" had an interval of 4h24m, so this doesn't automatically mean it will be a long interval.
19537 13 Sep 2021 @ 1350 --- Graham Slight rise in the pool from empty but still not covering much at all. Similar to the interval after the long stall on 9/9.
19535 13 Sep 2021 @ 0941 --- Graham First view in the pool and water rising, most rocks covered.
19408 09 Sep 2021 @ 1700 --- Graham Water level has come up slightly from the low/empty level. Still very low. Stopped rising about 1800. Still doing some slight rise and drop cycles. Some rocks still visible including the tip of the triangular rock on the right side.
19403 09 Sep 2021 @ 1125 --- Graham Slight drop in water level now Clepsydra is on strong. Slow drop continued until Fountain erupted.
19402 09 Sep 2021 @ 0858 --- Graham Water rising in Fountain. Hard to see prior to this but tops of rocks are still visible.
19208 31 Aug 2021 @ 1849 --- Graham Pool dropped slightly when Clepsydra turned on. Continued to drop until observations ceased with lack of light.
19194 31 Aug 2021 @ 1612 --- Graham Very small rise in the pool around time if 10th Clepsydra pause. 1612 2 to 2.5 feet down from the rim and slowly rising.
19054 24 Aug 2021 @ 1742 24 Aug 2021 @ 1901 minissa Arrived to find the entire Fountain area really quiet except for New Bellefontaine. Jets every 3-4 minutes but short and weak. Spasm came on fairly strong 1800. For the time we were there, Morning was quite full and continuing to rise. 1823 water rose in Fountain so visible from observation deck but then held at about 18 in below overflow. Clepsydra alternated periods of quiet with periods of activity during which mainly vents 2 and 3 erupted with many blue bubbles and excellent height. We reported to Tara, who said this was a stall and, while we had a 50/50 chance of getting Fountain as long as Clep alternated starting and stoppi g, the more likely scenario was an eruption 7.5 to 10.5 hours after previous Fountain eruption.
19011 23 Aug 2021 @ 0900 --- steve Fountain area, PEANOT is full and overflowing but not erupting. Jet and Super Frying Pan are off. No water in Spasm. Bearclaw is growling but nothing is making it to the surface. Clep is ie. Jelly is too low to see the water level.
18640 23 Jul 2021 @ 2220 24 Jul 2021 @ 0030 Tara No eruption during this time. Stall behavior: Fountain and Morning water levels high, Spasm high and surging 2-4', Clepsydra pausing and restarting periodically, Jet rumbling constantly with erratic eruptions. Clepsydra last pause 0013 and last restart 0016, steady from then until 0030 when I left the area. I am confident the 10h interval is closed.
18423 14 Jul 2021 @ 1110 14 Jul 2021 @ 1305 Tara No eruption during this time
17966 21 Jun 2021 @ 1544 --- Scott H tour guide report seeing Fountsin between 1530 and 1600
17783 14 Jun 2021 @ 0001 14 Jun 2021 @ 1200 aferrara Electronic logger seems to be missing some (not all) mid-day eruptions. Eruptions observed directly are not always represented in the logger data in that time period. Long intervals, as always, may or may not represent closed intervals, even with the assistance of the electronic logger.
17785 14 Jun 2021 @ 0835 --- Graham Empty and damp. Clepsydra side pool water high. Clepsydra on steady, not trying to pause. Ftn must have erupted recently, maybe 0700 to 0730? (0737 per Lynn) Spasm empty. No water visible in Jelly. 0850 water slightly higher in Ftn but still full of rocks. No water visible in Morning. 0905 Jelly water rising, deep in the vent. 0920, 0935 unchanged, Jelly slowly rising. 0950 Fountain water level down a little to "normal" level. 1005 Clepsydra side vent boiling on left side. 1020 unchanged. 1035 water barely visible in Morning. 1050 unchanged.
17758 13 Jun 2021 @ 1630 13 Jun 2021 @ 1920 Tara high water level in Fountain and Morning, Spasm full & intermittently bursting 2-4', Clepsydra pausing, Jet dry and grumbling. Water levels rose in F, M, & MT which showed visible boiling at 1806. Jet grumbling got louder until it erupted at 1800. Clepsydra last pause 1822, on at 1826, full strength & steady at 1835. F, M, & MT dropped a few inches after Clep became steady, no eruptions from any of the 3 as of 1920. Will fill in more details later.

15644 18 Aug 2020 @ 1850 18 Aug 2020 @ 2115 BrandonC Observed from great fountain and checked fountain from 2030-2115 Good pool when I was leaving
15564 13 Aug 2020 @ 1319 13 Aug 2020 @ 1343 JSJ Highest water during Fountain Geyser's 1:19 to 1:43 PM eruption was about 66 feet.
15529 11 Aug 2020 @ 1450 11 Aug 2020 @ 1516 JSJ Inclinometer reading: highest water during Fountain Geyser's 2:50 to 3:16 PM eruption was about 58 feet.
15152 02 Aug 2020 @ 1731 --- JSJ Inclinometer reading: highest water during Fountain Geyser's 5:31 to 6:02 PM eruption was about 75 feet.
15056 20 Jul 2020 @ 1745 --- William no water visible
15038 19 Jul 2020 @ 1420 19 Jul 2020 @ 1445 Yates Was driving and didn’t catch the precise time but was ie on my way from Norris to UGB
14855 02 Jul 2020 @ 0815 --- Graham Clep side pool splashy. Spasm down. Jelly dropping. PEANOT down but filling.
14680 19 Jun 2020 @ 0900 --- Ben VL Visitors reported to me a fountain duration exceeding 40 minutes for an eruption sometime this morning. Their description matched an eruption of fountain so I thought I should make a note.
14640 14 Jun 2020 @ 1748 --- CraigC From Great Fountain observed steam rise just above the trees in the area of Fountain when no steam had been visible for the previous 20 minutes
14629 13 Jun 2020 @ 1406 --- William post eruptive, clep paused
14048 22 Dec 2019 @ 2033 --- Micah Kipple No fountain yet.
14045 20 Dec 2019 @ 0909 --- Micah Kipple Water very high in both Fountain and Morning. Clepsydra Weak and pausing infrequently.
13892 06 Oct 2019 @ 0726 --- jkgood I believe I just missed an eruption. Water in shoulder pools still steaming. Clep was off on arrival at 7:26- restarted 7:29/ stopped again ~7:34- back on 7:41 Jet grumbling and boardwalk spattered by SPF
13881 04 Oct 2019 @ 1844 --- Tara no eruption as of this time.
13877 04 Oct 2019 @ 1800 --- Tara Water level extremely high in both Fountain and Morning. Water well out the "neck" of Ftn, maybe 1 foot below rim. Looks to be a stall, though I did not see any unusual behavior from Clepsydra during my time observing the group.
13783 23 Sep 2019 @ 0903 --- mroseum logger battery dead
13772 20 Sep 2019 @ 1840 --- Ben VL Clep side vent empty splashing. Water in Morning well below island. A couple jets observed. My guess is somewhere mid-cycle between two eruptions.
13661 12 Sep 2019 @ 1218 --- Barbara Lasseter 2 parallel steams from fountain area as seen from FLdr
13640 10 Sep 2019 @ 0811 --- Barbara Lasseter Big steam began as seen from Thud pullout. Ended 0848. Clepsydra steam continued for30 min after
13484 29 Aug 2019 @ 0000 --- mroseum Fountain Logger only shows later morning starting 8/29. No electronic back-logs before that can be made
13140 10 Aug 2019 @ 0620 --- RMichaels Based on water surrounding platform, no water seen in Morning or Fountain, and Clepsydra's side vent being full of water, I would assume an eruption occurred sometime in previous hour.
13060 05 Aug 2019 @ 2119 --- Stephen_Gemar No eruption of Fountain as of 19:19. Water had been sitting part way up the crater, almost to the top of the large dark notch on the back of Fountain’s crater, and didn’t seem to move during our observation.
12939 01 Aug 2019 @ 1421 01 Aug 2019 @ 1458 JSJ Inclinometer: highest water at least ~58 feet. Saw a taller spout but didn't get a chance to measure.
