Clepsydra was on strong, CSV down, Spasm empty, Jelly ~3' down, Jet active. Beaches were small and the puddles in front of Fountain were still draining/drying, so I would estimate about 60-90 minutes since the previous eruption ended. |

Arrived at 11:38. Clepsydra going strong. P.E.A.N.O.T was half full and bubbling. Nothing else. Caught Spasm ie at11:45. NO other activity. Fountain, as noted, at 12:10. Possible Morning's Thief at12:14. Hard to see through steam. After Fountain stopped, only change was Spasm had stopped. At 12:52, Jet started rumbling, but never went while I was there. Clepsydra paused at 12:46, resumed at 12:54,paused again at12:58, and resumed at 13:05. No other changes when I left at 13:10. |

Another observer reported that at 0800, Clepsydra was on strong, CSV empty, and fairly high water level in Jelly. Jet had been grumbly and erratic. When Ftn water level became visible at about 1030, most of the rocks were covered, indicating a relatively short stall (2-3 hrs of Clepsydra pauses). This water level held with only slight variation until 1306 when it began cycles of drop and rise with the water level gradually lowering. Larger drops at 1423 and 1432 led up to the final rise at 1435. No water was visible in MT until over a minute into Fountain. No SFP seen. |

looks like stall recovery. Morning is almost full, and Fountain quite high. Clepsydra is on steady, and Jelly is still in overflow out the back. 1844: an hour after I saw Clep on steady while approaching from north, Jelly is still in overflow out the back. Spasm off since I arrived. No boil in Morning, and I think it has dropped a bit. |
