Full Description

SS 65855 48925 A cairn, visible as a grass covered stoney mound, 13 metres in diameter and 1.3 metres maximum height. The cairn, one of two circular features noted by McDonnell [1] on 1946 aerial photographs [2], is in a ploughed field now under pasture. It is prominently situated on the edge of a northwest projecting hillspur overlooking the deep valley of Heddon's Mouth Cleave with panoramic visibility. It is constructed on the slope and its south side is about 0.1 metres high and the downhill, north side, about 1.3 metres high. Part of the centre is eroded, exposing the content of small stones, and some furze covers the north side. The cairn could be a field clearance heap but its excellent situation, general appearance, symmetry and content of hand picked stone, suggests it is almost certainly a prehistoric cairn. The other feature noted by McDonnell is a circular hollow 33 metres to the southeast of the cairn at SS 65885 48906. It is about 11 metres diameter and 0.4 metres deep with the hollow slightly elongated towards the cairn. It may well be the source of the material of the cairn. Surveyed at 1:2500. [3] Both the cairn and the associated circular depression mentioned above are visible on aerial photographs. A second depression, located at SS 6724 4570 is also visible, measuring approximately 10 metres in diameter and cut into the slope of the valley above Heddon's Mouth Cleave. It is not clear from the aerial photographs whether these extractive pits, which are shown but not annotated on the 1st Edition Ordnance Survey map, are the source of material for the cairn or whether they represent later quarrying activity. N.B. SS 6724 4570 is a grid reference sited on the road just north of Parracombe Lane Head. This is clearly an incorrect grid reference. The National Mapping Project data supplied to the HER has, however, transcribed a third large cut feature at SS 6579 4893, which is likely to be the feature mentioned above. [4-7] The site is also visible on aerial photography taken in 1978. [8] The 25 inch 1st Edition map also depicts a similar earthwork feature at SS 6594 4886. This earthwork is the only one to be depicted on the 25 inch 2nd Edition map. [5,9]
