A trench was dug across the south side of the enclosure at West House Farm. The ditch was about 3ft 6" (1.1m) deep below the base of the modern topsoil and about 16ft (4.9m) wide. The 'loam' shown in the section can probably be equated with silt at the base of the ditch whereas the 'gravely loam' can be taken to be the back fill, presumably the bank redeposited into the partially silted up ditch. In the 'loam' was found some pottery now lost but apparently datable from the 8th century to c.30BC, whereas in the gravely loam was found a piece of Roman tile. Although not proved conclusively, the earthwork may have been Early or Middle Iron Age or Earlier.<2><3>
