Site Event/Activity record EHG3577 - Geophysical survey - John O'Groats House Hotel

Geomagnetic and earth resistance surveys were undertaken by Archaeological Services, Durham University in 2011 south of the John O'Groats Hotel over six areas within a proposed development site. The works comprised geomagnetic survey of all available areas, approximately 8ha within seven land parcels, and 1.6ha of targeted earth electrical resistance survey within five of those land parcels. All the survey areas were relatively noisy magnetically, possibly due to their use for vehicle rallies. The resistance survey detected the possible remains of stone footings in Areas 3 and 4, close to known early settelement evidence. Four probable large pits were detected in the west of the site and a system of drains was detected across the majority of the site. <1>
