The Iron Bacteria of August—7
August 24, 2014
You can see specks of the Leptothrix discophora film here, but the main attraction—in subject matter—is the iron oxide that is contributed, perhaps, by L. ochracea. I think what drew me to this particular spot, however, was all the triangular shapes, not only of the shale, but also in the poplar leaves.

The colors just pop in this, Linda. Wonderful composition, too.

Thanks, Ken. Yes, this orange is quite startling to see “in the flesh,” too.

when you take the time and share a close look tot this image , I see a surreal portrait formed by he eye of one leave. Iron bacteria is oxygen rich environment , still popped up the idea why they oxides iron in an almost pre-defined shape , not that randomly as nature often offers , bart

Now that you point it out, I can see that face, too. The orange color is in that shape because of the rock (shale) that it’s sitting upon. The rock is that shape, so the orange precipitate that has formed there is in that shape also. Thank you for writing, Bart.

Yes, it is, Kathy. I took this photograph August 10, but today on the way to the river I saw: birds flocking, sumac leaves turning, and even more leaves on the ground beside the river.
