Data from a Borehole Survey at North of Great Ouse (Westbury Viaduct), Westbury, Aylesbury Vale, Buckinghamshire, 207-2018 (HS2 Phase One)

This collection comprises of reports, spreadsheet, image, GIS and site record data from a borehole survey at north of Great Ouse (Westbury Viaduct), Westbury, Aylesbury Vale, Buckinghamshire, 207-2018.The results of the borehole investigation and deposit modelling have recorded an alluvial sequence (undated), which for the most part is inorganic with limited palaeoenvironmental potential. Where a localised more organic alluvium has been recorded associated with a palaeochannel, this still has a high mineral content and no true peat deposits were recorded. The sequences are waterlogged and have the potential to preserve organic remains, including wooden artefacts and/or riverside structures, although no archaeological remains or artefacts were recovered during the borehole work. No buried soils were noted, although the surface of the Pleistocene gravel should be considered a key archaeological horizon for the preservation of in situ artefact scatters and cut features prior to the onset of alluvial deposition. However, the direct below ground construction impacts for this Site are likely to be minimal and unlikely to reach the depth of either the organic alluvium or alluvial-gravel interface. No further work is recommended.
