Antiquarians and historians have been interested in the ditch since the 19th century, but much of its course has been built over. Between 1990 and 1997, the University of Manchester Archaeological Unit excavated sections of the ditch in Denton, Reddish, Levenshulme, and Platt Fields, in an attempt to determine its age and purpose. Although no date was established for the ditch's construction, the investigations revealed that the bank to the north of the ditch is of 20th century origin. Together with the ditch's profile, which is U-shaped rather than the V-shape typically used in military ditches and defenses, this suggests that the purpose of the earthwork was to mark a territorial boundary. The conclusion of the project was that the ditch was probably a boundary marker.
