Forty-one trenches were excavated, focusing on the anomalies of uncertain origin identified during the geophysical survey, with further trenches located in blank areas to test the reliability of the geophysical survey results. The trenches represented a 2% sample of the overall 10ha site area. The trenches were laid out using a GPS with sub-25mm accuracy, leaving a safety buffer zone on either side of an overhead electrical cable which bisected the site. No other adjustments to trench locations were required due to ground conditions or site obstructions. Trenches were located to investigate potentially significant anomalies recorded on the geophysical survey plot. The trenches were excavated, under the direct supervision of an archaeologist, using a 14-ton mechanical excavator fitted with a toothless bucket. The trenches measured 1.8m wide by 30m long. Spoil was stored adjacent to, but at a safe distance from, trench edges. Trenches and the upcast spoil were scanned with a metal detector on completion of machining. Machining continued in spits down to the top of the undisturbed natural geology or the first archaeological horizon, depending upon which was encountered first. Once archaeological deposits were exposed, further excavation proceeded by hand. The exposed surfaces were cleaned sufficiently to establish the presence/absence of archaeological remains. A sample of each feature or deposit type (for example furrows) was excavated and recorded. Excavation work carried out was sufficient to resolve the principal aims of the evaluation; Upon agreement with the Principal Archaeologist at Oxfordshire County Council, the trenches were backfilled. All features and deposits were issued with unique context numbers, and context recording was in accordance with established best practice and the OA field manual. Bulk finds were collected by context and no small finds were retrieved. No deposits suitable for environmental sampling were encountered. Iron Age features encountered in Trenches 19 and 22 were very shallow, poorly defined and disturbed, with a high proportion of residual artefacts, having been truncated by medieval and later cultivation. Digital photographs were taken of any archaeological features, deposits, areas and trenches and works in general. Plans were produced at an appropriate scale (normally 1:50 or 1:100) with larger scale plans of features as necessary. Section drawings of features were drawn at a scale of 1:20 and 1m-wide sample sections...
