No pause in eruption during this time. When observed up close from 1800-1812, the eruption appeared normal, pool vent full and bursting, main vertical vent on strong and no steam vent activity or unusual sounds. Group seems to be in a stall but if Clepsydra was pausing, it was before my arrival. |

Clep’s Side Vent appears to have broken off more of the sinter on the right side of its crater. The crater has expanded since my last viewing earlier today. CSV has been occasionally splashing during observation. |

Steam vent first heard from top of stairs at 1020, continued on loudly for about 2 hours. At about 1220 I noticed the sound had gotten weaker, but the angled jet from the steam vent was still reaching 15-20 feet. Still making the audible "whoomp" sound as I left the area at 1250. |

I was chatting with a tour guide on our way out just before Fountain (about 2035), who said Clepsydra was off when he was there in the morning. Figure it is somewhere in this window. |

Vent on the right went into loud steam phase at some point during the dual. Sounded like a supersonic jet flying overhead, just a little quieter. Steam phase died down and stopped not too long before Ftn quit. |

Only change from 1125 note was a visible water level in the front vent at 1325. At 1348, the steam vent started and was on for about a minute, then Super Frying Pan started and it went back to splashing. The water level dropped in the front vent at about this time and after that it had only weak splashes. At 1415 the steam vent turned on and stayed on until at least 1545. |
