A series of linear cropmarks to the north-west of Rhydonen farm. The 1st edition mapping of Denbighshire (sheet XIV 10, 1875) denotes a boundary running the length of field from north-east to south-west. Further linear cropmarks are evident from aerial reconnaissance on 24th July 2010 by RCAHMW, and it is likely these are associated boundary cropmarks.
