This report describes the results of an archaeological field survey of the Bhaltos peninsula in Lewis. The results are assessed in the light of both older research and the continuing programmes of excavation and palaeoenvironmental analysis in the area. The examples and distributions of various site-types provide a comparison with more general models recently proposed for settlement in the Western Isles and appear to suggest a series of settlement discontinuities in the Iron Age, Norse and medieval periods.
