Fitz’s ‘megalithic jumble’ is a spot on description for this site.
Sitting on a mound/knoll, the two most visible sections of the kerbing do look to have once described a circle.
But the two small quarries that look to have disturbed quite large sections of the kerbing have made the whole thing a bit hard to grasp.
Well worth a look, with some great views out towards the Howgill Fells.
