This is Sneaton Moor, 8km south of Whitby. It was both a QL and Starfish site intended to lure the bombers away from Teesside.
There is no record as to how successful this site was.

An aerial view of the site gives a clearer indication of remaining earthworks.
I believe the track visible bottom left is the one that enters the area from John's Cross.
