| 34899 | 04 Jun 2024 @ 1037 | 04 Jun 2024 @ 1437 | JSJ | No Sentry Geyser eruptions. "Long" Outpost eruptions result in pool filling of Outpost's basin. Once the water level is high enough, splashing through an undercut (next to Sentry) occurs. Others have mistaken this activity for Sentry eruptions. Sentry's basin fills with water from this splashing. Between Outpost eruptions, the water level in Sentry's basin very slowly decreases, but is never out of sight, and is calm. |
