A number of field-boundaries originally visible on the ground were destroyed in the building of Druidale Reservoir in 1980 and the opportunity was taken to examine these before they were lost. The north-south boundary, running along the break of the slope on the west side of the valley, consisted of a broad earth and turf bank. A large quantity of rubble formed a rough facing to the bank, spreading into the body of the bank. Although not giving a specific date to these boundaries, Morris implied that they were elements of a farming economy, dating to the period from the 17th to 19th centuries.
