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.

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.

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.
