Site Event/Activity record ESF25927 - Evaluation - Proposed Reservoir Lodge Road, Walberswick

Evaluation trenching was carried out on the site of a proposed irrigation reservoir. Thirty trenches were excavated and were positioned to target a number of anomalies that had been identified during a preceding magnetometer survey. The trial trenches confirmed that many of the anomalies noted by the survey were due to the presence of archaeological features. In the majority of trenches the natural subsoil comprised a stiff boulder clay with chalk, either pale yellow or occasionally grey in colour. The natural subsoil lay directly below the ploughsoil, at a depth of c.0.3m. Modern plough-lines were visible in most trenches indicating the subsoil has been truncated.
