Site Event/Activity record EEM14113 - 2011: RS; MS - Porlock Stone Circle

The site was subject to geophysical survey in 2011. Resistivity was undertaken on a 60x60m area, which revealed a number of anomalies, including three sub-rectangular high resistance features that appear to cluster around the circle (in a petal-like manner) with a fourth amongst the moor grass to the northwest. A pair of linked semi-circular high-resistance features in the southwest corner of the survey area also appeared to be structural. Unfortunately, there was no clear indication of any discrete trenching within the circle area and it was thought that only large-scale area excavation would provide evidence for previous excavations. A fluxgate gradiometry survey on a 40x60m subset was then focused on the stones but revealed little more than an apparently random spread of isolated magnetic anomalies, with the exception of two clusters of such anomalies (one adjacent to the southeast edge of the circle and one to the northwest) that could be indicative of more sustained disturbance.
