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.

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.

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.

I pass this slab of quarried sandstone nearly every time I visit Schoepfle Garden. It never looks the same. The first photograph is from my trip this past Sunday, April 14. The second is from about a year ago, April 18, 2017, and the third is from August 26, 2017. I know there are others . . .

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.
