Other Iron Bacteria of Late September—2
October 16, 2014
Such quantity (see yesterday’s post) of iron oxide is not a problem in the Vermilion River. The next rain dispersed and swept these flocs downriver into Lake Erie, where it is never—as far as I know—a problem either. Where it is a problem is in Appalachia and the West, where poor mining practices leave this or related material in place or in small streams where it smothers vegetation. There they call stuff like this acid mine drainage or Yellow Boy I’ve never seen these mining sites, but I have the feeling that I would not find them as attractive as what I see along the beautiful Vermilion River. . . . If you’ve been receiving my photographs for very long, you know that this rock slab is shale.
Romancing Reality 
A very square piece of shale?

Yes, I’m always amazed at the regular shapes this shale breaks into.

I reckon it is an old roof tile 🙂

The manager of the department I work in at the museum is a geologist and he has some beautiful collections I can’t wait to photograph. It won’t be the same as being outdoors and discovering them the first time but it’s still exciting for me. I think I can relate to your excitement when you find something like this.

I’m sure you do, Ken. Have fun photographing those specimens. Can’t wait to see what you get.
