19955 10 Oct 2021 @ 1754 --- SantaFe108 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.
