Geophysical Survey - Antonine Wall

NS 951 797 The Antonine Ditch has been detected by the magnetic survey but the anomaly varies in strength and definition; it does not appear with any clarity in the resistance results. The Rampart has been identified tentatively and intermittently in the resistance data, but has remained largely undetected by the magnetic survey. Anomalies which might relate to the Military Way are apparent in the magnetic results but the interpretation is far from confident and alternative origins are equally, if not more likely. Neither geophysical technique has successfully mapped the limits of the Fort or detected any of its main defences. Resistance anomalies within the presumed area of the fort may reflect rubble associated with collapsed buildings but no discrete wall lines have been identified. Both surveys have yielded anomalies associated with cropmarks, but the exact nature and function of these features remains unclear. Since excavation has confirmed the presence and survival of archaeological features at Inveravon, their general under-representation in the geophysical datasets is attributed to a combination of natural and modern factors.
