Scheduled Monument Report:

The monument includes the remains of a cross dyke which runs for 130m above a saddle of ground in a north west to south east ridge. It is thought that the monument was once a much longer feature running between steep slopes on either side of the ridge. The dyke comprises an earthen bank 4m-6m wide standing to a maximum height of 1m with a ditch 2.5m wide and 0.5m deep on the south side of the bank. Clennell Street, a medieval drove road, passes through a gap in the cross dyke but its relationship with the monument is uncertain. It is thought that the cross dyke is prehistoric in origin and marks a territorial division which may have been reused during the medieval period. The fence line which crosses the cross dyke from south east to north west is excluded from the scheduling but the ground beneath it is included.

Comments:

Analysis shows that there maybe another Dyke missing from the Scheduled Monument that joins this Dyke with NT91943 08021 (1008274) in the direction of old quarries.
