Culvert

1 A ground penetrating radar survey provided evidence for the culvert observed at the base of the excavated old access chamber.
2 A second phase of ground penetrating radar survey was undertaken to further investigate the course of the culvert to the west and in the vicinity of the churchyard. The results were not conclusive. A number of promising anomalies were found on some of the radar transects but adjacent transects, confusingly, often showed no comparable anomalies. Nonetheless a route for the culvert was suggested.
