When I went dumpster hunting last month (see the small haul), I stopped by the old bank drive-through that has entertained me so often. I’d never been there in freezing weather, and icy new appearances awaited me. The last three photographs are what I will enter into the FAVA Six-State Photography show early next year, hoping one will be juried in.

Here’s a closer view of the sulfur bacteria in action. See also the post of October 21, 2014, which explains where the sulfur comes from.

Another element that associates with bacteria in water the way iron does is sulfur. The evidence in Ohio’s Vermilion River is more rare than the evidence for iron bacteria (shown in yesterday’s post), but it was there last month.

I saw some Leptothrix discophora films at Schoepfle Garden last month. Here is one patch, with details of the overall photograph beneath.

I tagged this photograph with “lichen,” but I’m not really certain that the white marks on the large rock are lichens. What else could they be? Fossils in the stone?
Later in the Day
Scientist-husband David suggests “mineralized inclusions in the rock. Could be of biological or abiotic origin from what little I can see.”
We now have two more opinions favoring the lichen theory: One is from my husband’s colleague in the Oberlin College Department of Biology, and one is from Art Murphy, who usually knows a fossil when he sees one. (See Art and Fossils.)

Now that we’ve moved back to Oberlin, I don’t go to Schoepfle Garden as often as I used to when it was a half-hour’s walk from home. I was there twice last month, though. I love to get there early.

When I spied this river from the bridge last month, I thought: Perfect, another photograph for my collection of brown photographs. I pulled over just beyond the bridge and walked back to take the photograph. It was only when I looked through the viewfinder that I realized how much blue was in the frame. This is either the East Branch Black River, the East Fork Black River, or the West Fork East Branch Black River. Unless it’s the West Branch Black River. When I wander about taking photographs, I only half know where I am. I knew I was east of the Vermilion River, so it has to be one of these.
