17889	18 Jun 2021 @ 1743	---	Craigmon99	Someone has thrown a chunk of boardwalk in Old Tardy C. Rangers said they will deal with it tomorrow as there are too many bison.
17531	07 Jun 2021 @ 0740	07 Jun 2021 @ 1640	Graham	No eruption seen during this period. I was watching from Tilts Baby so may have missed one.

5779	04 Sep 2017 @ 1628	---	Janet Jones	Heard a gurgle at depth. Crystal Spring had overflowed enough to flow into it and might have been part of that gurgle.
3202	22 Jun 2016 @ 1503	---	David	Water seen draining in to crater, and water in drainage from 14:59 eruption. See photo: https://www.flickr.com/photos/ujelang/27979999542/in/photolist-JCuP4d-HRiX6u-hhGHcZ
