The excavation comprised a programme of open area excavation within two areas of the proposed development. The two areas were targeted on the linear features revealed during the 2017 archaeological evaluation. All work specifically adhered to the written scheme of investigation laid out in a separate written scheme of investigation document (Oxford Archaeology 2017c). A 14-tonne 360� tracked excavator fitted with a 1.8m toothless ditching blade was used for the trenching. All machine work was carried out under the direct supervision of an experienced archaeologist. All topsoil was removed down to the first significant archaeological horizon in successive level spits, which in this case was the natural geological substrate. The top of the first significant archaeological horizon was cleared by the machine, but was then cleaned by hand and inspected for features. Sufficient of the archaeological features and deposits identified were excavated by hand through a specific or agreed sampling procedure to enable their date, nature, extent and condition to be described. No archaeological deposits were entirely removed. It was not necessarily expected that the whole of Areas 1 and 2 would be fully excavated to natural subsoil, but the depth of archaeological deposits across the whole site was assessed. The stratigraphy of Areas 1 and 2 was recorded even where no archaeological deposits were identified. Spoil heaps were monitored to allow for the recording of the spatial distribution of artefacts. All excavation, either by machine or by hand, was undertaken with a view to avoiding damage to any archaeological features or deposits that appeared to be worthy of preservation in situ. In June and July 2017 Oxford Archaeology was commissioned by Croudace Homes to undertake an archaeological excavation of land adjacent to Thame Road in Longwick, Buckinghamshire. The site, centred on NGR SP 7875 0525 and lying at 85m above Ordnance Datum, has been proposed for a new housing development. The excavation was undertaken to further investigate features that were discovered during the April 2017 evaluation by Oxford Archaeology. Two Areas were excavated (1 and 2) and this took place from the 27th June to the 3rd July 2017. The results of the excavation revealed part of a possible Roman trackway orientated NNW-SSE, which may have linked to the Lower Icknield Way (a prehistoric or Roman trackway) to the south. This trackway was formed by two ditches 10m apart containing Roman c...
