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. |

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. |

Steam vent on from near the end of Morning through after the end of Fountain. Impressively loud and with angled jet left to right behind the main vertical jet, sometimes almost as tall as the vertical jet. As Fountain continued, it became more steam than water. |

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. |
