This fieldwalking study has been commissioned by Gifford and Partners Ltd on behalf of Swayfields Ltd., to assess the archaeological potential of the development area (centred TL 235 366). This report is written in response to the Revised Brief for Archaeological Evaluation, prepared by Mr G. Burleigh, Keeper of Field Archaeology for North Hertfordshire District Council. Only the worked flint distribution would appear to warrant further comment. In the absence of greater contextual control, it is difficult to assign precise ages to any of the recovered material, although a palimpsest ranging from the Earlier Neolithic through to the Bronze Age seems fairly uncontroversial. This conclusion is in accord with other surveys of the Cambridgeshire/Hertfordshire chalkland, where long term prehistoric land-use has been documented.
