20791 12 Jul 2021 @ 1919 12 Jul 2021 @ 2039 Graham Note that SteveO was present and reported that the webcam entries were NOT eruptions of OT Drain. Likely just steam from something. The in-park eruption at 1933 is good. There is also a high probability that the Old tardy wc times are not eruptions as SteveO didnt post them.
