Monument record MBC43677 - post-medieval ditch and probable extractive pit, Blackland Farm

A post-medieval ditch and probable extractive pit is visible on historic aerial photographs as earthworks and was mapped as part of the North Buckinghamshire Aerial Investigation and Mapping project (EBC18304). Located in a field about 413 metres WNW of Blackland Farm and centred at SP 82156 25913, is a 9 metres square pit with an open side facing ENE, with earthwork spoil banked on the NNE and WSW facing side. Centred some 50 metres ENE is a 151 metres long curvilinear ditch about 2 metres wide, aligned WNW-SE. Its function is uncertain. These features are constructed on a block of medieval and/or post medieval ridge and furrow cultivation. On aerial photographs taken in 2019 and recent remote sensing data, the feature is not visible and appears to have been plough-levelled (1-3).
