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.
12870 29 Jul 2019 @ 2005 --- Tara Fountain's formation and runoff channel still wet. Clepsydra side vent about a half inch below rim, gently bubbling and pulsating. Back side if Morning dry. Puddles around Morning's Thief.
12790 24 Jul 2019 @ 1545 --- Tara No eruption yet since 0615ie Fountain. No water or much steam from Morning's Thief as of 1530. Water level in Morning was rising extremely slowly and as of 1530 had not covered the "island" next to the peninsula on the left side of the crater. It had a lazy boil with very little convection at that time.
12508 17 Jul 2019 @ 1355 17 Jul 2019 @ 1445 Tara Formation dry, water levels in Fountain and Morning looked like Fountain was in eruption window, Jet initial at 1412.
12484 14 Jul 2019 @ 1301 --- jazzknick Water slowly rising in Fountain and Morning, approx 2 inches per hour est. apart from Clepsydra, no other associated features active.
12483 14 Jul 2019 @ 1231 14 Jul 2019 @ 1233 jazzknick Fountain & Morning water level 3 ft below rim and gently steaming. Runoff channels dry in 83 degrees temps. No other features active except Clepsydra is.
12470 13 Jul 2019 @ 0505 --- ypcaribou Two tall columns of steam seen from road southbound. One was Clepsydra. Other to left of Clepsydra.
12461 12 Jul 2019 @ 1820 --- Tara No eruption as of 1820, water visible in Morning's Thief starting at 1712.
12406 07 Jul 2019 @ 0520 --- LynnS Steam in the north portion of the runoff channel east of the crater indicates Fountain recently erupted. Eruption finished before 0520
12052 30 Jun 2019 @ 0530 --- LynnS Clepsydra was ie, Fountain had recently finished an eruption. Clepsydra’s side vent still a blue pool filled with water. Jet was not erupting at one to five minute intervals so the recent eruption of Fountain was not a dual with Morning.
11849 16 Jun 2019 @ 2050 --- LynnS Had not yet erupted
11780 14 Jun 2019 @ 0829 --- William post eruptive. water barely visible in Fountain, no water visible in Morning. New Thing mostly drained.

11735 11 Jun 2019 @ 1834 11 Jun 2019 @ 1907 JSJ Inclinometer reading: Fountain Geyser's eruption reached 60 to 64 feet high.
11652 08 Jun 2019 @ 0725 --- LynnS Water level in Clepsydra’s side vent (CSV) visible but pool is not completely full. Estimated time of most frequent Fountain eruption is about 1-1/12 to 2-1/2 hours ago based on other observations made over the past two weeks of the relationship between the water level in CSV and Fountain’s eruptions.
11641 07 Jun 2019 @ 2120 --- William no eruption prior to 21:20.
11640 07 Jun 2019 @ 2112 --- User34 Does not appear to have erupted by this time

11368 26 May 2019 @ 1558 --- Micah Kipple Surroundings are relatively dry and there is water visible in the crater
11472 23 May 2019 @ 1330 23 May 2019 @ 2100 Ben VL Arrived around 13:30 to find Clep pausing frequently and high water levels in Fountain and Morning. We all thought the behavior was odd, because we thought Fountain's interval was approaching 8h. Found out later that Fountain went short and erupted just under three hours before we arrived. Mystery solved. The Fountain group was in a stall for most of the afternoon. At 14:49, Fountain had water within a foot of overflow. Noted at 16:07 that Fountain appeared to be dropping. Water was high in Morning the whole time, and we did note convection at 14:37 as well as some bubbles later on and throughout a lot of the afternoon. Clepsydra was having long, frequent pauses early in the afternoon, the last one I noted started at 14:33. Jet was not in series as far as I'm aware when we arrived, but the activity slowly picked up throughout the day. Several Twig's - though I only noted one at 14:28 - and activity from other features. We first noticed bubbling in MT at 15:14. That eventually progressed to a boil, and an eruption at 20:28. We left after that. Just as we were about to go behind the trees driving away, saw Fountain's steam column start to rise. 20:42, likely ns. We went back to take a look. Just Fountain, with a beautiful sunset in the background. Could have been more MT's, did not stick around for duration.
11334 23 May 2019 @ 1300 23 May 2019 @ 1625 Kyle fountain in a stall. Clepsydra switching frequently from on to off. morning very full, less than 1 ft below rim. Fountain as full as less than 1 ft below rim and pushing up the "neck". Jet rumbling almost non stop but rarely showing any water

11251 16 May 2019 @ 1451 16 May 2019 @ 1653 bbev Water could be seen by standing on middle rail of boardwalk upon arrival. Water rose maybe 3-5" during 2 hours, and was still only visible standing on middle rail.
11170 05 May 2019 @ 0640 05 May 2019 @ 0654 RLJones It appears that fountain went off very recently. Both F and M are steaming, no water in Morning. Channel between F and M very wet. Frost on boardwalk except near F where there is water. Clepsydra is in full eruption. One eruption of Jet
