Excavations and environmental analysis of a mound and two barrows indicate that activity commenced within the range 3930–3520 cal BC with the construction of a large mound enclosed by a substantial ditch on a drumlin which had been largely cleared to grassland. A pollen sequence recovered from the fosse indicates that the drumlin remained under grassland for some time. It was still under grassland in the Iron Age when a pair of sequential barrows was constructed about the period 380 cal BC–cal AD 80. The earlier bowl barrow covered a pyre site with remains of an inhumation burial, and the later saucer barrow contained three token cremation deposits in the low mound and ditch, the last associated with the iron fittings from a wooden artefact. Pollen analysis of the ditch sequences from the barrows indicates that the drumlin remained open and heather-covered.
