The caves of the Gower peninsula are known to contain Late Pleistocene as well as Holocene sedimentary deposits and are therefore of particular interest to Quaternary scientists, including archaeologists specialising in the Palaeolithic period. Such cave deposits should be viewed as a valuable scientific resource. Here we report the findings of an assessment survey of the caves of Bishopston Valley, south-eastern Gower, utilising a methodology for non-invasive survey of caves sites which enables their archaeological potential to be assessed. Several of the caves in the Bishopston Valley contain deposits of potential archaeological importance. These deposits are under threat from human/animal use of the caves, and further investigation of these sites is warranted

A survey of the caves of Bishopston Valley, Gower, published previously in Cave and Karst Science (2010: Vol.37, No.2), identified cave sites with the potential to contain archaeological material within their sedimentary deposits, and assessed the conservation status of these sites. Two caves - Ogof Ci Coch and Valley Side Cave 1 - showed clear signs of recent anthropogenic and/or biogenic disturbance of their fill. Archaeological test excavation at both sites was undertaken in summer 2011, and the results are reported here. Ogof Ci Coch is demonstrated to be an archaeological cave containing Mesolithic and later prehistoric artefacts. However, archaeological material was only found within spoil deposits from a caving dig, now overlying intact but archaeologically sterile deposits near to the mouth of the cave. Archaeological interpretation of this material is therefore limited in scope. Valley Side Cave 1 was found to contain only disturbed deposits which are clearly the result of recent unauthorised excavation at the site. These findings have implications for the conservation and management of cave sites in Bishopston Valley.
