3459 09 Aug 2016 @ 1229 09 Aug 2016 @ 1553 JSJ Couldn't see all "Rejuvenated Geyser" eruptions due to parked vehicles sometimes blocking my view. The entries for this afternoon are not all guaranteed to be closed intervals. Considering this geyser's recent erratic intervals and durations, I'm sure I missed some.
