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 east-west boundary running up and down the slope consisted of a turf and earth bank with a few scattered stones.  Although not giving a specific date to these boundaries, Morris seems to imply that they were elements of a farming economy, dating to the period from the 17th to 19th centuries.
