A geoarchaeological borehole survey designed to record the alluvial profile and any associated deposits and to determine their archaeological and palaeo-environmental potential, was carried out by D Allen of WA in advance of office development on the flood plain of the river Wey. While there can be little doubt that the Wey and its flood plain would have been well utilized in the past, the sediment analysis indicated a fast-flowing water course which would have made the active flood plain environment unsuitable for settlement or occupation. No datable organic horizons were recovered which would have provided a chronological framework to relate to occupation in the vicinity. In palaeo-environmental terms, the lack of long-term stasis provides little potential for the recovery of evidence for the history of the local environment.
