Numerous lithic scatter sites have been identified within the Tweed valley many of which such as Craigsford Mains, Lauderdale consist of mixed material including typologically Early Mesolithic broad blade artefacts. These sites, though they have not had any focused excavation, appear to have been located in a rich, diverse riparian landscape. River junctions seem to have been important locations; for example, two sites Manor Bridge and Rink had large scatters of lithics (Warren 2001 63).
