Several linear earthwork banks and ditches, up to 5 metres in width, are visible on images derived from lidar data captured between 1998 and 2014 and on aerial photographs taken from 1947 onwards in the area west of Yarty House. Most of these correspond to field boundaries and probable drainage ditches depicted on late-19th century mapping, apart from a single linear ditch parallel to two probable water management ditches 60-70 metres to the north and south. This is the only feature that has been transcribed for his record, and it is interpreted as a drainage ditch of probable 19th century date that is part of a system to drain the land west of Yarty House.
