23267 19 Aug 2022 @ 1233 --- SantaFe108 End of eruption.
23266 19 Aug 2022 @ 1227 --- SantaFe108 Cliff's sign is missing from the boardwalk railing.
19369 08 Sep 2021 @ 1433 --- Dave W Empty crater
17762 14 Jun 2021 @ 0719 --- CraigC empty pool
17504 06 Jun 2021 @ 1119 --- CraigC empty pool
17035 09 May 2021 @ 1704 --- Micah Kipple First "Minor" following the end of the major eruption and draining of the crater.
15985 04 Sep 2020 @ 1128 --- Janet Jones I watched a few cycles of Cliff while at Black Sand Basin today - and none of them reached overflow. The sinter on the "left" corner remained dry. It would splash like a normal cycle, and was extra splashy at the end of each cycle before draining, but the pool never filled to the rim. Rainbow Pool was in full overflow the entire time I was here as well.
14243 26 May 2020 @ 1446 --- Janet Jones Watched a couple of cycles - it never filled to overflow. Bursts came about every minute with the final burst in the cycle lasting a bit longer.
13830 18 Sep 2019 @ 1113 --- Gilbert Now empty
5886 06 Sep 2017 @ 1856 --- Dave W Cliff off and pool completely empty.
4799 04 Aug 2017 @ 1235 04 Aug 2017 @ 1747 JSJ Cliff Geyser active with usual mix of behaviors: full pool spouting, low pool spouting, and pauses.
