The extent and character of the occupation area are assessed and shown to be extensive (300- 400m2). The environmental data demonstrate the limitations imposed by soil pollen and charcoal studies, suggestbut that area experiencedthe has possible hunter-gathering agriculturaland impacts, prior to soil deterioration and peat growth. An attempt is made to place the site in the wider context of the Mesolithic northernof Britain. INTRODUCTION Research shows that the south-west of Scotland was the location for widespread Mesolithic occupation (illu . Apars1) t fro lone mth g known coastal locatio possiblf no e settlement (Morrison 1980a; 1982) there was also an extensive inland presence of hunter-gatherer communities (Edwards et al 1983).

Apart fro earle mth y reference f Lacaillo s e (1954 unspecifieo t ) d localities producing artefacts, which were compared with the late Larnian of north-east Ireland, nothing had come to light until recently.

These were originally opened and worked by the Forestry Commission and local people continued to extract sand from them. Although the northern and southern quarries as well as the disturbed area in-between have produced Mesolithic materials, this paper will focus upon the northern area.
