Kammer,
Reminds me a little of the Wrynose stone, although that is in isolation. Still, similar to the photos on this forum post, it's a standing stone that provokes questions, and demands answers. I passed the Wrynose stone yesterday, on my way to The Burnmoor complex and eventually Scafell. The Wrynose stone was obvious, to the right hand side of the road as you drive up. It looked the business to me.
Cheers,
TE.
