Note IDStart TimeEnd TimeEntrantNote
4109 20 May 2017 @ 1915 20 May 2017 @ 1935 RLJones No water in FTN, Spasm, or Morning, Clepsydra steady. Jets at 1915. 1924. & about 1935. Left about 1935 with no eruption.
4108 20 May 2017 @ 1715 --- Tara No eruption as of 1635...left due to hail storm. Maureen stayed until 1715, still no eruption as of that time.
4104 20 May 2017 @ 0725 20 May 2017 @ 0740 RLJones No water visible in FTN, Morning, or Spasm. Clepsydra steady. No activity in Twig or Jet
4099 16 May 2017 @ 1500 16 May 2017 @ 2113 RLJones Bryon arrived at FTN at 1500, I arrived at 1655. We did not see each other until about 1807 and then began coordinating our observations. From 1500 until the FTN start at 2042, Bryon observed 24 stop - restarts by Clepsydra. From 1655 until the FTN start at 2042 I observed 9 Clepsydra stop - restarts. In the stop - restarts, when Jet started to erupt the boiling in Spasm decreased and Clepsydra stopped. When Clepsydra restarted Jet stopped and the Spasm boiling increased. At 1804 Jet started to erupt BUT Clepsydra and Spasm this time CONTINUED to erupt. After 1804 the seeming correlation ended and Clepsydra no longer appeared to affect, or be affected by Jet. Twig was on very frequenty from 1655 until I left at 2113. The Jet eruptions were very weak until just before the FTN start. Superfrying pan erupted at 2035 & 2040, just before the FTN start with some burst to 10+ft There were two short bursts from MT. The 2044 Bursts were to about 10 feet and the 2048 bursts to about 25ft. FTN stopped at 2109. When I left at 2113, Twig, Clepsydra, and Jet were still erupting. When Byron arrived at 1500 the Fountain area was dry and he guessed that the last FTN eruption happen 1 to 2 hours earlier. It was 5 hrs 42 minutes after Byron's arrival that FTN finally erupted at 2042. So, the interval had to be possibly 7 to 8 hrs or more. Note sure how this fits into the other Geyser Gazers recent observations, but it did make for an interesting and strange evening for the two of us.
4089 12 May 2017 @ 1902 --- Tara Away from Fountain from 1720 to 1902. Upon my return Spasm and Jelly were full, Twig and Peanot were dry, and Clepsydra was steady and strong, no pausing. Fountain and Morning maintained their high water levels.
4088 12 May 2017 @ 1622 12 May 2017 @ 1720 Tara Arrived at 1622 to find Twig and Spasm erupting, Jelly overflowing, Fountain and Morning at high water levels (18-24 inches below rim and "breathing"), Clepsydra pausing and restarting on a 5-7 minute cycle (pauses lasted 1-2 min), and Jet erupting every 8-10 minutes. Twig stopped at 1639. Seems very similar to behavior described by Steve C, Jim S, and others on the afternoon of May 5. I also saw similar behavior in November 2015 and October 2016.
3778 13 Oct 2016 @ 0956 --- Devin C. Could have been ie at 757 but the fog was really thick I could not confirm if it was erupting.
3740 01 Oct 2016 @ 1800 --- Tara No eruption as of 1800.
3738 01 Oct 2016 @ 1545 01 Oct 2016 @ 1621 Tara Area fairly dry, no runoff going into Spasm or drain hole. Fountain water level about 18 inches below rim. Water rose an inch or two in the 35 minutes I watched. Spasm and Jelly full. Very similar to behavior seen on closing day 2015.
3722 26 Sep 2016 @ 1315 --- Tara Morning completely empty. Fountain runoff still wet. Trickle of water still running into Spasm. Had finished by 1305, so estimating eruption time at 1230.
3631 09 Sep 2016 @ 0608 --- Art Appeared to be ie at 0608 however lighting was too dim to be 100% certain.
3505 18 Aug 2016 @ 2040 --- Tara Clepsydra was OFF as seen from the parking lot. Fountain may have had a very short interval in the 4-hour range.
3190 03 Jul 2016 @ 0904 --- Graham No water visible in Morning. Fountain. not ready.
2914 29 May 2016 @ 0500 --- LynnS Finished before 0500. No steam cloud visible as I came in sight at 0500. 0515 runoff still steamy. Twig or. Clepsydra pause 0521 to 0525.
2837 13 May 2016 @ 0853 --- RLJones FTN, Morning, MT, all steaming. No water visible in Morning.
2638 26 Dec 2015 @ 1500 --- Tara Large steam cloud seen from a distance, probable i.e. time based on Clepsydra pause in progress at 1520.
2602 01 Nov 2015 @ 0830 01 Nov 2015 @ 1300 Tara When Byron arrived at 0830, Fountain and Morning both high, within 2 feet of rim and "breathing" up and down by a few inches. Spasm full and erupting, Jelly full, Jet grumbling and erupting at short, irregular intervals. Clepsydra was starting and stopping every 3-4 minutes until 0940 when it turned on and stayed on. Water levels dropped slightly in Jelly and Spasm by 1000. Twig 1005 d=1h07m. Super Frying Pan 1025 d~9m. No Fountain as of 1302.
2590 30 Oct 2015 @ 1810 --- Tara No Fountain as of 1810, interval at least 5h43m
2539 12 Oct 2015 @ 1645 12 Oct 2015 @ 1945 SteveO Water level in Fountain down about 2 feet from the rim, water level in Morning clearly visible from the boardwalk in front of Fountain. Spasm boiling over both vent & overflowing in to Jelly, Jelly full & overflowing. Water level stayed the same during the time there was enough light to see.
2383 19 Sep 2015 @ 1040 --- deanl Fountain and Morning were empty and the platform wet when I arrived.
2249 03 Sep 2015 @ 0815 03 Sep 2015 @ 0825 RLJones Morning: no water visible, strong convection. Fountain outflow channel to SW was dry.
2220 30 Aug 2015 @ 0928 --- Tara Standing water level in Fountain high enough to partially cover some rocks below the "neck" and easily visible to me standing on the boardwalk. Water also unusually high in Morning.
2069 09 Aug 2015 @ 0735 09 Aug 2015 @ 0750 RLJones Jet active, Twig not active, no water visible in Morning
1860 07 Jul 2015 @ 0800 --- udo Fountain Paint Pots parking lot and boardwalks will be closed all day today 7/7. Reopens 7/8.
1565 06 May 2015 @ 1215 --- Jake catch basin and runoff channel wet. guessing it erupted within the last 90 minutes
1555 02 May 2015 @ 1847 --- Maureen Fountain POST eruptive at 1847. Clepsydra off twice. No Twig. Morning drained upon arrival, making possible start time as early as 1815.
1532 22 Apr 2015 @ 0820 --- cb From the observation deck: Twig was dry, peanot water was 3/4 full and bubbling, no visible water in Morning or Fountain, Clep on, SFP ie @0820. Looks like the "shelf" on SFP is still intact.
1531 21 Apr 2015 @ 1600 --- udo Fountain Paint Pots trail is partly open. The crew was taking down the barricades to the parking lot as we drove by this afternoon.
1235 14 Sep 2014 @ 0859 --- Barbara Lasseter ended at 0859 per gazer report

1157 28 Aug 2014 @ 1004 --- udo Fountain Twig and Jet areas were wet at 1004.
865 04 Sep 2013 @ 0000 --- Graham No Fountain by 0000. One Mornings Thief
792 05 May 2013 @ 0845 --- Maureen Seen post eruptive at 0845. I was there at 9, guessing it erupted between 0700 and 0800
791 02 May 2013 @ 1030 02 May 2013 @ 2100 steve Fountain was observed from 1030 to 2100 witn no eruption. Fountain rose to a high level over four hours, then dropped back down about a foot and stayed there. Odd day. More to follow
680 01 Nov 2012 @ 0000 01 Nov 2012 @ 0630 Maureen Steve reported Twig in eruption with big runoff field, we are thinking between 0600 and 0630 for Fountain this morning.
515 28 Sep 2012 @ 1800 28 Sep 2012 @ 2000 Jake didn\'t see a steam cloud from GF @ 1900, observed Twig late ie @ 2000...guessing Fountain went @ 1800
473 17 Sep 2012 @ 0940 17 Sep 2012 @ 1045 Maureen Erupted after 0940 and before 1000. Too foggy in basin to see steam cloud and when I went back up, Twig was in eruption at 1045.
379 04 Aug 2012 @ 2325 05 Aug 2012 @ 0000 Maureen Erupted at 2325 last evening. Did not stay for the duration.
364 23 Jul 2012 @ 1600 --- Maureen Twig ie at 1600, walked up to see what happened and it looked like Flountain had erupted before 1500 if I had to guess. Shorter intervals maybe?
363 23 Jul 2012 @ 0600 --- Maureen Finished erupting by 0600, Twig was ie.
264 09 Jun 2012 @ 1215 --- Maureen at 1215 Twig was i.e...so Fountain end before that. Not sure what is up now, hope to find it tomorrow.
215 03 May 2012 @ 0000 03 May 2012 @ 2359 Maureen 48 minute eruption!!! This must mean 12 hour interval is at play yet so far no closed intervals seen.
189 28 Apr 2012 @ 1535 --- Maureen Twig in eruption at 15:35, boardwalk very wet, Fountain eruption around 15:00? Maybe shorter intervals are commencing!
163 23 Apr 2012 @ 0849 --- Maureen Twig I.e. at 0849. Best guess for Fountain is 0800. Possible Fountain again after 1600 yet could also be 2000.
160 21 Apr 2012 @ 2155 --- Jake Fountain had not erupted by 2155 on 4/21
157 20 Apr 2012 @ 0000 20 Apr 2012 @ 2359 Maureen Fountain maybe around 8:10? Guess, it was off by the time I arrived. No twig. Stayed until 4:18, so over 7 huor interval. 2 Morning\'s Thiefs, 15:30, and 15:49
