On the E facing slopes of Halidon Hill, the cropmark remains of a possible hillfort, identified as Conundrum South by Gates and Deegan (2009) and as Halidon HIll Iron Age Fort by Northumberland HER. The site was first identified on an aerial photograph taken in 1992 (Glover 2006), satellite imagery taken in 2006 shows an area of many geological features which confuses the interpretation. It lies at approximately 100m OD with the ground rising to the W. Elsewhere it slopes away in all directions especially in the E. The cropmark comprises an arc of two curvilinear ditches 9m apart, the inner measuring some 5m in breadth. The remainder of the feature is now under modern plantation. The site is unrecorded on OS mapping. No investigation of the site has been carried out and it is undated.
