At West Heslerton, North Yorkshire continuing excavations in advance of sand extraction have recovered 11,500 flint artefacts from an area of 5ha. The assemblage was formed during discrete episodes of occupation throughout prehistory from the Late Mesolithic right through to the Late Bronze age/ Early Iron Age. Various methods of deposition are represented including in situ manufacture and use, occupation spreads and deliberate deposits in pits and graves.
A fieldwalking exercise by the Lanark and District Archaeology Society covered 300 acres ploughed in advance of forestry planting. Over 2200 flaked lithics were recovered including flint, chert and pitchstone. The assemblage represented activity in the area dating from the Late Mesolithic to the Bronze Age.
