Sites

As it was expected that there could be sub-surface archaeological material, attention was given to areas where the underlying soil and rock were exposed, namely the worked slopes of the existing quarry as well as open patches along the north-western edge of the polygon - where it slopes down towards the stream. In some areas, a layer of medium to coarse, ferruginised sandstone gravel and small cobbles was evident between the base of the topsoil and the weathered granite bedrock. It could be observed in situ at the edges of the worked slopes. It had been partly removed from some surfaces and dumped, together with the topsoil, in heaps close by. Chunks of naturally-occuring vein quartz were evident on the gravel surface and in the heaps. It seems likely that this gravel layer would be the horizon containing archaeological material. Twelve Stone Age artefacts were seen in association with the gravel and in the heaps throughout the affected area. Although cobbles were noted in the heaps of soil, they were not abundant. The archaeological material mostly consists of quartzite artefacts, some clearly ESA or MSA, whereas others are likely to be ESA and/or MSA in origin. Only the MSA point was noted along the north-western edge of the affected area. Except for a possible core, no convincing artefactual flaking of quartz was observed. All the material was in a disturbed, secondary context due to quarrying activities.
