Title Stonehenge Southern WHS Survey, West Amesbury, Wiltshire, Report On Geophysical Surveys, October 2015
Summary Caesium magnetometer and Ground Penetrating Radar (GPR) surveys were conducted at West Amesbury Farm, Amesbury, Wiltshire, as part of the Stonehenge World Heritage Site (SWHS) Southern Landscape Project. The vehicle towed caesium magnetometer survey (21.7ha) enhanced the location of linear anomalies, mainly representing boundary, enclosure or field systems identified through aerial photography, and ditches associated with a square enclosure, the Coneybury Henge and two barrows. One of the barrow ring-ditches produced a very weak response and, potentially, represents a previously unknown monument. High sample density GPR survey (17.3ha) produced similar results, although the data was dominated by the strong response of the underlying geomorphology, and also indicates a wider pattern of linear anomalies. Both geophysical techniques identified an extensive distribution of discrete pit-type anomalies across the survey area, although some of these are likely to represent tree throws rather than deliberate cut features.
