Click on the link below, and page down to the photos of the stone circle of Elva Plain. Does the close-up of the marked stone remind anyone of the Polissoir Stone near Avebury?

If so, it's remarkably understated. I wonder of some of the Great Langdale stone axes were sharpened there on their way to Scotland.

Can anyone throw any light on it?
