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. |

back from break. Spasm still ie (normal) and still no Jet. Fountain a little higher - almost covering the bigger rock that had my marker. SFP in steam so erupted in my absence. 1800: Jelly in overflow in back channels. 1850: Fountain has risen a little since 1745, and we just saw splashing in MT. 1854: Fountain seems to be dropping. then rising, dropping again (all around the MT).

I arrived about 1440 (Clep on solid, no Jet, Spasm, Twig, or SFP), saw wet places on the platform, and entered an "A" time of 1330. However, this eems strange to me: i could see water in Morning from the deck and water in Fountain 10-12" below the rectangle. Now, at about 1515, water has risen markedly in Morning and is easily visible in Fountain at the base of the rectangle. Was there a brief stall? Hmmm. I plan to watch and update. 1530 - water up to 1/4 of the rectangle. 1550: water even higher in Morning and 1/2 up rectangle in Fountain. 1615: rectangle covered. 1630: slow rise & cover a couple more marker rocks right of the rectangle, then stop. Morning visible from lowest landing. 1705: water in Morning visible from second step up on lowest landing - no chg in Fountain. 1715: Fountain has risen to cover marker hole on big rock right of rectangle. 1725: take a break |
