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.
