25390 12 May 2023 @ 1428 --- Janet Jones The overflow channel is devoid of microbes. It had microbes in March, but that could have been due to the weather/time of year. In looking back at other photos, it does seem to be hot enough at times to not have microbes and cool enough other times to allow for their growth. This does not appear to be necessarily seasonal.

97 07 Feb 2012 @ 1226 --- BB This is one of those days where it is hard to tell from the UGB cam what Little Cub is doing. I am pretty sure from my captures that Little Cub was 1226 ns. But KL posted 1216, and I assume he was watching the streaming cam, hard to be wrong about LC there.
