The possible chambered cairn at Westfield is about 36ft in diameter and 3ft 6ins high; a large slab protrudes from the centre.

RCAHMS 1911; A S Henshall 1963.

This grass-covered cairn measures 23.0m NE-SW by 19.0m transversely, and is 1.7m high. Several large stones are evident in the top, but there is no conclusive evidence of a chamber.

Resurveyed at 1:2500.

Visited by OS (RD) 2 November 1964.

(ND 0572 6357) Cairn (NR)

OS 1:10,000 map, (1975)

A cairn, as described by the previous OS field investigator, left free from ploughing at the edge of a field. The stone in the centre (noted by Miss Henshall) is unlike the slabs commonly found in cairn chambers, and it has probably been dumped here from the adjoining field. There is no evidence for a chamber.

Visited by OS (N K B) 18 September 1981.

This chambered cairn occupies a small rise at the side of a flat field at 50m OD. When visited in 1910 the cairn, then at the edge of a grass park, had a diameter of about 11m and was about 1m high (supra). In recent years the field has been ploughed but an area around the cairn and extending to the adjacent field has been left rough and has probably been augmented by field-gathered stones. Thus it is now very difficult to trace the edge of the cairn. On the E side two substantial partly exposed horizontal stones may indicate its limit, and an indefinite edge may be seen on the NW side, but elsewhere it merges into the rough ground. The height of the cairn is about 1.5m. The indications suggest a diameter of approximately 12m. The tops of three orthostats are exposed in the centre of the cairn. They have intact upper edges, and the N stone is a waterworn block somewhat taller than the other two. The sizes and disposition of the orthostats suggest they may be the portal stone, a side-slab and the back-slab of a polygonal chamber, probably entered from the E. The stones are 0.75 and 1.35m apart. They are 0.35, 0.75 and 1.25m long by 0.15, 0.4 and 0.25m thick. The E and W stones project only 0.15m, but the taller N stone is exposed for 0.55m on its N side where the cairn material is lower.
