Details:
While crossing a hiking trail bridge along the sandstone cliffs of the Hocking Hills region of Ohio, I came across this colorful scene along a creek's edge.
The Sun was drifting in and out of clouds that were causing some iridescence in the sky that was reflected in the creek. The rainbow sheen on the rocky shore is caused by a thin film of bacteria that lives off the iron leaching out of the rocks.
I wonder if an iron-eating bacteria will be found on Mars someday.
