Piggledene, North Farm, Overton, Wiltshire: Report on Geophysical Survey, September 2008
Author(s): Neil Linford
A geophysical survey was conducted at Piggledene, North Farm, Overton, Wilts., over the proposed site of a field experiment to determine a model for the formation of the old land surface layer observed during recent excavation at Silbury Hill. Soils at the site match parent material underlying the old land surface layer at Silbury and the current geophysical survey was requested to select an area with a minimal likelihood of disturbing any existing archaeological remains. Magnetic survey undertaken with fluxgate gradiometers revealed a number of linear anomalies, possibly associated with a late-prehistoric field system or, more probably, medieval ridge and furrow. Other discrete pit-type responses and negative linear anomalies were recorded, but these are probably related to field clearance activities. The survey has identified a suitable area for establishing the field test site and confirmed, through a topographic survey, that the slope of the terrain falls within the desired range for the experiment.
