NS 545 720 In May 1995, GUARD undertook a resistivity survey across the line of the southern extent of the ditch of the Roman Fort at Bearsden. The intention was to determine whether the ditch had a causeway on the southern side.

Conditions were poor for the survey, the soil being loose and giving very low resistance readings. However, two areas of anomalous readings were encountered, one being interpreted as the excavation trench from the 1980s and the other a possibility for a causeway.

However, in view of the conditions, any interpretation remains tentative.
