Unusual Single Wall NYM

I must have walked close to this wall many times over the years and not noticed it before.  Its the only wall I know in the NYM which consists of a single wall composed with the foundation stones all set on edge.  It is a small enclosure just   A few yards to the south of the gravel track running down off the moor into Glaisdale.  Some of the stones are massive.  The wall is some four to five feet in hight and a couple of feet in width.
