Iridescence along the River 7


August 6, 2018

When the water level recedes, it leaves traces of the Leptothrix discophora film on the rocks and mud. The close crop shows the iridescence best. Click on it to see the image even bigger. (The paw prints are from a raccoon.)

The detail crops show more of what drew my eye. The puckering indicates loss of water from the film.

As promised, here come the photos of the Leptothrix discophora biofilms I saw along the Vermilion River July 14. Those of you new to this blog may find a brief introduction to what you see in this photograph useful. Those wanting to know more may care to explore some links.

I saw more crystallized (if that’s what it is) ice along the Vermilion River March 26. My daughter assures me that this is ice that has partially thawed and then refrozen. She lives on a lake and often has observed this kind of ice along the shore.
