33809 16 Jan 2024 @ 0805 --- K.Cooper audible steam
27992 04 Sep 2023 @ 0826 --- Graham Eruptions observed in the last few days appear to be taller than in the spring, peaking at 3 feet.
25599 20 May 2023 @ 1751 --- SantaFe108 Intermittently splashing 6 inches tall.
25232 23 Apr 2023 @ 1544 --- SantaFe108 Low splashing <6 inches tall sustained for about 10 seconds, followed by a pause of 20 or so seconds, then another ~10 seconds of low splashing.
21799 06 Jun 2022 @ 1747 --- SantaFe108 Frequent small splashing without erupting.
19955 10 Oct 2021 @ 1754 --- SantaFe108 (wc) Sustained, moderate-to-low height play for 15 seconds. Possibly a minor eruption or very large pre-play. Camera panned away for Old Faithful so I couldn't see if there was a full-sized eruption after.
19512 12 Sep 2021 @ 1507 --- SantaFe108 (wc) Small non-eruptive splashing at 1507/08, and also at 1509. Both episodes lasted only seconds.
19217 31 Aug 2021 @ 1845 31 Aug 2021 @ 1901 SantaFe108 (wc) UNNG-GHG-18 "Marmot's Tail" N-NE of Marmot Cave and W-SW of Plate. A small eruption started at 1845, followed by an increase to almost full height (~1'), which fizzled out within seconds. More small eruptions occured every few minutes, all of them incredibly small and durations of only seconds. This lasted until the next full-sized eruption at 1901. I am unsure if it continued after.
