A trial trench was located to investigate a linear cropmark. Opening of the trench identified a single ditch in the eastern end of the trench. It had a broadly NW-SW alignment with a U-shaped profile, 1.4m wide and 0.4m deep. It was filled with three deposits of sandy silt, which did not contain any artefacts.

The undated ditch may correspond with the recorded cropmark, but it may also be the remains of a former field boundary as depicted on the 1st edition Ordnance Survey map.
