Irregularly shaped pits and banks, between 10-58 metres long, are visible as earthworks on visualisations derived from lidar data captured in 2013 and 2019.
The pits and banks correspond with earthworks labelled as ‘Quarry’ on the late-19th century First Edition Ordnance Survey map and as ‘Old Quarry’ on the early-20th century Second Edition Ordnance Survey map.
The earthworks are therefore interpreted as post-medieval or 19th century quarries and spoil heaps, that had passed out of use by the early-20th century. They are possibly associated with workings recorded in proximity to the south-east MDV69024.
One of the earthwork pits at SX43746465 corresponds with a cut feature recorded from aerial photographs of 1946 as part of the Tamar Valley NMP project. This earthwork has been re-transcribed during this survey from lidar data which has provided additional clarity and detail as well as improved spatial accuracy, but which was unavailable to the previous survey.
The earthworks are not clearly visible on other available aerial imagery owing to thick tree cover.
