All closed intervals. Outpost Geyser is still having shorts (S) and longs (L), like last season, but not alternating back and forth. Observed eruptions today: SSSLSLSSSLSSLSSLSSLSSSLSSLSSLSSLSLSSLSSLSS. Out of 42 eruptions, 29 were shorts (= 69%) and 13 were longs (= 31%). |

All closed intervals. Alternating long (~3 to 4 minute durations) and short eruptions (less than 1 minute long). Long eruptions include splashing from undercut ledge - this is NOT Sentry erupting. Water splashes into Sentry's basin, which was mostly water-filled and had a submerged microbial ring. |

All closed intervals. All eruptions started with low pool splashing. Alternating long and short eruptions - no exceptions. "Short" eruption durations were <1 minute. "Long" eruption durations were ~3 to 4 minutes. Splashing through an undercut geyserite ledge during Outpost eruptions gives the illusion of a separate vent erupting - it's not Sentry Geyser. |

Outpost appears to be bimodal. It has weak (minor?) eruptions that don't completely fill the pool and last ~40 seconds followed by about ~3-4 minute intervals. Then it also had 3-4 minute long strong eruptions with Sentry followed by 11-12 minute intervals.
EDIT: Sentry is not erupting during the long eruptions of Outpost. The vent that is erupting is part of Outpost's pool, referred to as the "undercut ledge" by James St. John. |

Outpost Geyser observed to have frequent spitting/very low spouting (just visible from boardwalk). Pool/basin on the immediate NNE side of Outpost Geyser was empty. |
