This a confusing one. There is a ring cairn which I believe to be Circle 278 just beyond a far more interesting jumble of stones*, which appear to have been moved about somewhat. There is clearly confusion over the name of this mix of stone; please refer to my weblog for a more in-depth discussion.
It’s all very lovely, nonetheless!
*Edit by TMA Ed: the “jumble of stones” is now generally thought to be Monument 280“.
