Although the words are gone the pattern left from the delamination and lichen looks as if the spirit has left its own image.
Sandstone is durable, yet soft enough to carve. A few sandstone markers are so well preserved that individual chisel marks are discernible, while others have delaminated and crumbled to dust overtime. De lamination occurs when moisture gets between the layers of the sandstone. As it freezes and expands the layers flake off.
