On my walk at Occoquan Bay National Wildlife Refuge, I happened upon these shells neatly arranged on a split log.  Somebody went through the trouble of finding the shells and then arranging them in the log.  All the work so I can happen upon the shells and have something to take a picture of.  Amazing.  Thank you, unknown artist!

And before I forget.  One more picture of an autumn leaf.

Or leaves.

Green ones too.
