iridescence

Here’s another 2002 photo, taken October 12 of that year, that also happens to be in They Breathe Iron. We had a drought in northern Ohio in 2002, which gave the iron bacteria a field day—many field days. This is because the rains didn’t disperse the bacteria and wash them downstream, so their colonies could grow to (in my eyes) wonderful proportions. This is the iridescent film of the iron bacterium Leptothrix discophora.
