Old Bank Drive-Through 21


December 13, 2018

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.

 

 

 

 

 


Not Leptothrix discophora—Vintage or Otherwise


November 13, 2018

A week ago Friday I was in the parking lot of our nearby drug store, waiting for my passenger to finish her shopping. It’s boring just to wait for someone. Enter my iPhone! It had just finished raining. What lucky timing. These are not Leptothrix discophora films but thin films of oil or gasoline on the puddles, which is what L. discophora films are often taken for. You can see why. Both exhibit color interference, also called thin-film interference. These films—unlike films of L. discophora—have no fracturing. (Compare with images in the previous post.)

Fabian Oefner is an artist who uses thin films of oil in his work.

 

 

 

  

 


Vintage Leptothrix discophora


November 3, 2018

This summer and fall have seen far too much rain to produce much in the way of colorful Leptothrix discophora films. But I miss them, so this post delves into photographs I took of this evidence of iron bacteria along Ohio’s Vermilion River between 2008 and 2010, before I’d started the blog. Some of these photos may be repeats of other dives into the archives. I hope that since I can’t remember if I’ve shown them, you can’t either.

 

 

 

 

 

 

 


Cucumber Falls 4


August 12, 2018

Walking back up the stairs from the place of dark rocks and reflecting pools, you notice that the trail’s low wooden guard rail could very easily be breached and that you could, if you wanted, walk over to where Cucumber Run runs over the edge of the cliff. Hmmm.

 

 


Cucumber Falls 3

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


Cucumber Falls 2


August 10, 2018

Strictly speaking, this photograph does not show the falls but the pooled and slowly moving water of Cucumber Run between the falls and the Youghiogheny River. The colors in the water are reflected trees and sky.


Cucumber Falls 1


August 9, 2018

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.

Crossing the River


July 29, 2018

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.


Barton Dam on the Huron River

The Barton Dam on the Huron River is in Ann Arbor, where I took this photograph five years ago.
