Data from a Borehole Investigation at St John's Covert (Colne Valley Viaduct), Denham, Buckinghamshire, 2017-2018 (HS2 Phase One)

This collection comprises the reports, borehole logs and photographic archive for deposit modelling with boreholes at St John's Covert (Colne Valley Viaduct) Buckinghamshire. Work was undertaken by Cotswold Oxford Pre-Construct Archaeology (COPA) between November and December 2017. The purpose of this phase of work was rapid prospection of the sub-surface sedimentary sequence in the absence of historical ground data. The results of the borehole investigation and deposit modelling demonstrate the presence of an alluvial and peat sequence preserved beneath variable thickness of made ground.
