The wall itself is modest, roughly half a metre wide and barely forty centimetres high, yet it runs intermittently for about 130 metres eastward from the cliff edge into a small valley, following a roughly east-west axis with a slight, almost organic curve. What makes it genuinely curious is where it stops: thirteen metres or so short of a nineteenth-century earthen cliff boundary, the wall simply disappears, and small indentations in the turf suggest its stones were lifted and reused to build that later boundary. One structure cannibalised by another, the older absorbed into the newer without ceremony.

The wall appears in several disconnected stretches, some visible where the grassy sward has been broken by peat cutting, others protruding directly from the ground surface. Where peat cutting has exposed a cross-section, the wall can be seen sitting directly on the old mineral subsoil beneath the peat, indicating that it predates the bog growth that has since partly buried and obscured it. This places its construction in a period when the land surface here looked quite different, before the peat accumulated to its present depth. A second, similar stretch of wall lies about 105 metres to the south-east and downslope, running close to a small stream, suggesting that this was once a more extensive system of field division across this part of the island. The documentation of these remains draws on Christiaan Corlett's 2001 work, as well as the Royal Irish Academy's 2007 survey of Clare Island's archaeology, edited by Paul Gosling, Conleth Manning, and John Waddell.
