For the Edge assignment, I thought of this headstone. The right edge is lost in the tree, and the bottom of the left edge is actually fully enveloped. I wonder if, given enough time, the tree would swallow it completely?
One the other side of the same tree, another stone has been pushed out of alignment. It’s amazing what nature can do. Slow and steady wins the race.
This was found in the same Revolutionary War-era cemetery as my post for Pop of Color.
