Here you can see the Youghiogheny River in the distance, muddy from recent rains.

You may remember, from reading this blog, that my friend’s farm in southern Pennsylvania is near the Ohiopyle Falls on the Youghiogheny River. This year the adventure leaving from the farmhouse was to a tributary of the Youghiogheny called the Cucumber Falls.

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.

Two weeks ago I made my way to the Vermilion River, something I do less often than I used to now that we are living back in town. The river still charms me, I’m happy to say, and I was in special good luck July 14 because the river’s water level was low and its banks embellished with iridescent patches of Leptothrix discophora. When the water is low, I get to wade across to the other side, where I usually can find more colonies of my favorite bacterium (photos to come). The wade itself is a treat, though, and I love seeing the ripples filled with sunshine at my feet.

Walking along the opposite bank, eyes mostly on the ground in front of me, I wasn’t expecting this.
