19592 15 Sep 2021 @ 1807 15 Sep 2021 @ 1825 Graham Having 2 to 4min intervals when I walked up. Muxh shorter than usual.. Then a longer interval after this.
19037 24 Aug 2021 @ 1200 24 Aug 2021 @ 1530 William No activity during this time, started to try to erupt at 15:30
18680 26 Jul 2021 @ 1341 26 Jul 2021 @ 1425 aferrara Gizmo filled and overflowed rapidly as Castle started, and remained at high water throughout the eruption. After Castle transitioned to steam (1356) it drained. Gizmo slowly filled after that, beginning to expel water by 1409. No eruptions observed before I left at 1425.
17902 19 Jun 2021 @ 0750 --- User34 First overflow
17532 07 Jun 2021 @ 0740 07 Jun 2021 @ 1540 Graham No eruption seen during this period.

2340 13 Sep 2015 @ 1442 --- LotusBaker appears to have minors about 5 to 8 minutes after long period starts
1561 04 May 2015 @ 1425 04 May 2015 @ 1434 Janet Jones Gizmo was erupting about every two minutes during this time for a duration of about 30 seconds each with each ending in a few seconds of steam. Sometimes "Gizmo's Pool" erupted and sometimes not. (Was there a small pool with Gizmo before??? Have to check photos on that). Yet two other times at Gizmo, no eruptions happened for the 10-15 min I was there. More to come on this on the GeyserWatch.com blog as I have time.
