Other Iron Bacteria of Late September—1

October 15, 2014

Enamored as I am with Leptothrix discophora films, I also get a kick out of the rusty deposits (flocs) that the iron bacteria precipitate out of the water. On the same day that I found the prismatic films whose photographs I have been posting these two weeks, I was negotiating a somewhat treacherous part of slanted riverbank. I had my eyes and total concentration on my feet and walking stick. As soon as I felt safe, I looked up and heard my breath leave my body in an involuntary gasp. I’m not sure I’ve ever seen such a large swath of flocs. While some flocs sat directly on the shale, others coated filamentous or puffy bits of algae. The first photo shows a detail; the second is a composite of the complete expanse. To me, it was a beautiful sight.

    • Glad you’re still with me, Ken. I’m sure this stuff isn’t to everyone’s liking.

  2. Thanks for posting the wider view – it’s always nice to have context, though not necessary. 🙂

  3. You’re welcome, Lynn. I’m trying to include context more lately. It’s a lot harder for me to make a decent photo that way, rather than as a close-up. But I know I have something to learn by at least trying, and learning something is always fun—after I feel as if I’ve made a little progress. This particular wider view is not “a decent photo” in the way I’m thinking about, but maybe it can act as a signal of my intent.
