EAB161 - Geophysical Survey 1987 - CASTLE OF WARDHOUSE

Resisitivity survey used to detect possible stone structures within the enclosed summit area, and magnetometry was used to investigate the nature of the ditch network. Areas of high resistance on the platform were identified as the possible remains of stone buildings and surfaces and used to locate excavation trench Area 2. The line of a curtain wall or rampart was also recorded, curving around the summit edge. The magnetometer survey located the triple set of main enclosing ditches already seen on the aerial photos. Additional possible concentric outer ditch lines were also recorded, especially to the north-west. These have not been tested by excavation. Subsurface interface radar also used.
