Husks of History: Seneca Stone Cutting Mill & One Dead Turtle

The red stone for the Smithsonian Castle was cut at the Seneca Stone Cutting Mill, off Riley's Lock of the C&O Canal. Ruins of the mill are still open to the public.

I'd forgotten about the ruins, but when I turned left at the turtle resting in peace on the path, I stumbled into them, one historical remnant leading to another.

Thanks, Mr. Turtle.
