21506 25 May 2022 @ 2005 25 May 2022 @ 2140 Micah Kipple Approximately every 3 minutes, Bulger would grumble, boil, splash, and surge up to a foot above the rim for about a minute.
21040 19 Apr 2022 @ 1350 19 Apr 2022 @ 1445 RMichaels Splashed every few minutes for durations of 30-90 seconds. Some splashes ejected water from the crater, so the activity could technically be considered a long series of weak minors. After observing for a while it just seemed like pre-play building up to the next major. The intervals were not consistent like long series of minors observed in prior seasons.
