Geograph - photograph every grid square

Three parallel and very straight banks, each approximately 10m apart, run for some distance and their age and purpose are unknown. They are not shown on the earliest OS maps but were probably missed off before aerial photography was used for survey. Could they be a very old land division between the adjacent hill forts of Fawdon Hill (west) and Colwell Hill (Camp Hill; east), or are they more modern? The south end of the feature, west of the disused Closehead Quarry, continues as a double line of parallel banks, probably as far as the main road, east of Otterburn. At the northern end of the feature, east of Fawdon hill fort, only the eastern line is followed by the modern boundary.

Information on an eighteenth century plan held by the farmer indicate that it was a boundary between two farms and consisted of an enclosed track and adjacent forested windbreak. Possible connection with the nearby Battle of Otterburn is considered unlikely.
