Kettley Stone

23-4-03. I had just been up to Kettley crag and decided to investigate the Kettley Stone marked on the OS map; this rock is the only feature in the immediate vecinity so I presume this is it.
It’s in a very sheltered little valley, with a fort, settlements and rockart nearby. Only the rabbits here now.

Does anyone know anything about it please ?
Can’t find it in my book.
