Geophysical surveys were carried out by GUARD in 2004 over two features (Nos 46 and 89) recorded in previous walkover and topographic surveys in 2001 (see EHG3147) to the west of Loch Borralie. These were undertaken as part of initial work in the first season of the 5-year Strathnaver Province Viking-Medieval Archaeology Project. The survey was carried out over the interiors and immediate vicinities of both structures. A magnetometry survey was conducted in conjunction with a resistivity survey using 0.5 m mobile probe separations. Two 20 m by 20 m grids were surveyed employing a 1 m grid separation value, providing 400 readings per grid. The magnetometry survey was carried out using an FM36 Fluxgate Gradiometer. The resistivity survey was completed using an RM15 resistivity meter employing a twin electrode configuration with an inter electrode spacing of 0.5 m. <1>
