The Anglezarke/Rivington uplands of central Lancashire have, in recent years, suffered severe erosion. In response a programme of field survey was undertaken during 1983 and 1985, supplemented by palynological investigation, modern vegetation survey, and sample excavation. Two sites were investigated in detail, a cairn of likely Bronze Age date and a flint scatter of earlier Mesolithic type. The field survey demonstrated human activity on the upland throughout the prehistoric period and emphasised the heavy post-medieval exploitation of the moorland. Sample excavation confirmed the prehistoric activity and, in the case of the Mesolithic site at Rushy Brow, demonstrated the possibility of recognising and reconstructing periods of prehistoric activity of very short duration — perhaps only a few hours.
