ie at this time from previous eruption. Parasite vent is still on however it is weaker. Regular south pressure pool vent is bubbling which is noteworthy as is north pressure pool. |

0935 water level rising, parasite vent off, south pool slightly murky. after rising to overflow, the south pool had increasingly vigorous boiling and no bubbles from the parasite vent. during this time Thumping Hole was splashing to 1-1.5', and its water level rose enough to create runoff. Penta water level also up with slightly silty water |

In the duration of the 8:11 eruption, I walked up to see the two main pools bursting to a foot at most, however 5 vents in the front were going bezerk, shooting water around 2 to 3 feet in the air very rapidly. |

The near constant back vent in the right pool was paused with occainsial spalshes until 1344. It had strong eruptive episodes with frequent pauses for the rest of the eruption. |

Heavy steaming from Spasmodic Geyser area. Possible minor eruption? Area usually doesn’t steam like this. |

Spasmodic is perpetually erupting from the back vent within the righthand pool. The back vent between the two pools is occasionally erupting up to 2 meters. I have seen no other vents while sitting here. |
