A ditch or trackway located on Rough Shaw, the north facing slope of Deangate Ridge, has been mapped from aerial photographs as part of the English Heritage: Hoo Peninsula Landscape Project. The date of this feature is uncertain, but a Medieval or Post Medieval origin seems the most likely. It is possibly associated with twentieth century military activity in the area, including a First World War anti aircraft battery, the Lodge Hill Armaments Depot, parts of the Hoo Stop Line and a Second World War defended locality. The feature is 182m long with bank on downhill (northern) side.
