Two vents closest to the boardwalk are flooded together. Third vent is pulsing water within its cone. |

Water is high enough that the two bottom vents' pools have merged into one. Water is hot and steaming, but no boiling in any of the vents. I can see water in one of the cone vents, and it's rising and falling maybe an inch or two every second or two. |

Even though Churn is active, Penta is not. There's a large snow bank in the runoff channel. |

I witnessed Penta having a steam/mixed type eruption sometime between 1600 and 1730, the spray was probably reaching somewhere between 5-10 feet. |
