Areas of the site were stripped mechanically under archaeological supervision and all archaeological features investigated by hand. A sporadic watching brief was also maintained during extraction for possible Palaeolithic material. Long-running investigations have added considerably to the evidence for Palaeolithic, Mesolithic, Neolithic and Bronze Age use of this landscape, both for occupation and fr funerary activities. The chronology is supported by seven radiocarbon dates. The Iron Age, Roman and Medieval periods are also represented to a lesser extent.
