EHG5628 - Geophysical surveys - John O'Groats Mill, Caithness

Geophysical surveys were undertaken by Rose Geophysical Consultants in 2013 as part of a wider archaeological evaluation of John O'Groat's Mill, Caithness and the surrounding area. Following the walkover and DBA by AOC Archaeology (see EHG5627) two areas were selected for survey. Available areas surrounding the Mill were investigated using resistance survey. Gradiometer survey was not carried out over these areas due to the large amount of ferrous material within and adjacent to the survey area. Although the walkover survey did not identify any potential sites in the three pasture fields to the east of the Mill, geophysical survey was undertaken in the area adjacent to the Mill to assist with possible future developments at the site. Interpretation of the results of the resistance survey in the areas within the Mill complex (Areas A & B) are complicated by the limited areas available for survey, making it difficult to place anomalies within a wider context. However, survey has identified some responses of potential interest including possible structures and mill races. Survey within the pasture field to the east has not detected any archaeologically significant anomalies, with the data being dominated by responses from drainage features and agricultural activity. <1>
