A drystone structure built into the southern facing hillside and constructed from stones varying in size between 10cmsq to 1msq. The structure is located in a 'corner' of outcrops but there is a gap of 2m between the structure edge and the eastern outcrop. The structure also slopes with the natural gradient. At its highest [and most northerly] point it reaches a height of 3m, and at its most southerly, lowest point, it is only 0.5m. Noted during an upland survey conducted by Archaeophysica during 2005-6
