The trenches were laid out using a GPS with sub 50mm accuracy. Minor adjustments to the original positions of Trenches 38, 42 and 44 were required due to the presence of overhead electricity cables. Trench 37 was shortened in length slightly due to the presence of a live service. Trench 98 was extended slightly to pick up an anomaly from the geophysical survey. Trench locations were scanned with a Cable Avoidance Tool (CAT scanner) prior to and during excavation. The trenches were excavated using an appropriately powered mechanical excavator fitted with a toothless ditching bucket under the direct supervision of an archaeologist. Spoil was stored adjacent to, but at a safe distance from, trench edges. 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 had been exposed, further excavation proceeded by hand. 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. Small finds and samples were allocated unique numbers. Bulk finds were collected by context. Digital photos were taken of any archaeological features, deposits, trenches and evaluation work in general. Plans were drawn at an appropriate scale with larger scale plans of features as necessary. Section drawings of features were drawn at a scale of 1:20. All section drawings were located on the appropriate plan. The absolute height (mOD) of all principal strata and features, and the section datum lines, were calculated and indicated on the drawings. The trench and sample sections were located using either a GPS unit or total station. Coordinates relative to Ordnance Survey and Ordnance Datum were obtained for each sampling location. The majority of revealed features were sample excavated, unless with the agreement of the Wiltshire County Archaeologist. Where features were undated then greater levels of hand excavation than outlined in the agreed WSI were undertaken, including 100% excavation of some smaller features. Upon agreement with the Wiltshire County Archaeologist, the trenches were backfilled. During September and October 2018 Oxford Archaeology undertook a trial trench evaluation comprising 105 trenches targeted on geophysical anomalies at land at Kingsdown to the northeast of Swindon, Wiltshire (centred on NGR SU 15763 89598). The site is bisected by...
