EHG4892 - Geophysical Survey - Cnoc Tigh

The site comprises two main elements: - the denuded remains of a thick walled dry-stone roundhouse overlain by an irregular shaped enclosure. An as earthwork the roundhouse survives as a sub-circular grassy bank with a c. 17m in internal diameter, c. 5.5m wide and 0.8m in height. No entrance was visible and its interior is obscured by an irregular dry-stone enclosure, c. 14m by 12m. The wall of this later enclosure is 0.5m wide and 0.2m high with a possible entrance located to the north-east. Following extensive removal of the dense vegetation across the knoll the visible components of the site were digitally surveyed. In addition, on the invitation of Candy Hatherley, the RCAHMS archaeology team surveyed the site with a plane table in February 2014. Earth resistance survey was conducted by Oskar Sveinbjarnason of the University of Aberdeen on a 40 x 20 m area immediately to the south-west of the knoll using a TR/CIA resistance meter. The north and south areas of the survey identified large and broad anomalies of high and low resistance likely to represent the underlying geology or natural soils. The findings were not investigated during the later intervention stage as the field was under crop at the time of the excavation. <1>
