Mesolithic to Modern: living on sand at Gwithian, Cornwall
7th November, 2017Tom Walker Gwithian, on the east of St Ives Bay, has revealed evidence of human presence from the Mesolithic to twentieth century tin mining activity, with multiple episodes of settlement and abandonment. Environmental studies can show how the landscape has altered over the millennia, and how climate changes have influenced the phases of occupation. A recent project consisting of a programme of coring, down to 10m depth, as well as one test pit, will be discussed. Numerous different analytical techniques, together with dating on multiple samples, has improved knowledge of the sequence of changes in the river valley from early marsh to major pollution from the upstream tin mining. The siting and timing of human activity can often be related to secular climate change, associated with sand stability/instability.
