River Walk with More Shale

August 27, 2012

Saturday was another day of sunshine and low water in the river. We’ve had enough rain lately that many of the rocks along the river have sprouted moss. Algae are more prevalent, too. And still—I assume because we’ve also had extended days of heat and sunshine—the iron bacteria have been visibly at work. Trees or their shadows overhang the shore on the “other” side of the river, where I took these photographs. So in the second photograph you see a lot of shade with the sun barely illuminating an area of wet shale covered with algae. The rust colors are the result of the bacteria having deposited iron oxide on the shale and algae. What you see in the third photo is what happens when a shaft of sunlight strikes a leaf (sycamore?) in a few inches of water populated by algae (and probably cyanobacteria, the dark blue-green color), some of which has been layered with iron oxide by the iron bacteria.

    I like these quite a lot, especially the bottom one. Nice work!

    • Thanks, Ken. One of my friends said the stuff in the bottom photograph looked too slimy. I told her I wasn’t going to eat it, but that didn’t seem to make a difference. Glad you like it!

  2. Extraordinary beauty in the ordinary small things of life that so many of us would walk straight past without a second glance. Well seen Linda. That looks like a Sycamore leaf or something from the same Genus.

    • Thank you, Andy. That’s what I try for: to see something special about something common. Of course after I’ve seen it, I wonder how common it could have been in the first place, but oh well. My joy is in the hunt as much as the capture. Thanks for the support on Sycamore. Sycamore trees do line this river, but with just a bit of the leaf showing in that photograph, I wasn’t really sure.
