The current walled area, roughly D-shaped and measuring about 70 metres east to west and 40 metres north to south, represents only the southern and central extent of the original site. The ground tells the rest of the story in subtler ways.

Running northwards from the present enclosure, a low scarp, roughly half a metre high and about six metres wide, traces the outline of an earlier, more expansive graveyard that would have formed a large sub-oval area stretching approximately 85 metres from north to south. A scarp, in this context, is the slight but readable earthen edge left behind when ground has been deliberately shaped or long used, and here it marks the ghost of a boundary that no longer exists in stone. A further area immediately to the west of the current graveyard wall, defined by its own scarp of similar dimensions, may also have belonged to this original extent. The church at Buolick, which occupies the northern edge of the present graveyard, adds another layer to the site's long occupation. Among the headstones found both inside the church and throughout the graveyard, the earliest recorded dates to 1750 and stands against the west wall of the chancel arch, sheltered within the old church fabric. The graveyard remains in active use for burials today, meaning it is a place where centuries of commemoration continue without interruption, the eighteenth-century stones quietly neighbouring the recent ones.
