What survives measures roughly ten metres across, the drystone construction sitting between four and six centimetres below the surface of the surrounding peat, with only a low remnant of wall still visible above ground. Drystone construction relies entirely on the careful stacking of unmortared stone, and in the uplands of Kerry it has been used for boundaries and enclosures across many centuries. Here, the wall reaches no more than forty centimetres in height at its tallest, and it diminishes further as it runs from north to south, giving the impression of something caught mid-disappearance.

The enclosure sits within a wider field system, which suggests this was once part of an organised agricultural landscape rather than an isolated structure. Bog formation is a gradual process; peat accumulates over waterlogged ground across centuries or even millennia, and when it begins to cover earlier human activity, it can preserve what would otherwise erode entirely. The wall at Gearhanagoul, sixty-five centimetres thick at its base, is modest by any measure, but its survival within the bog means it retains something of the shape and intention of whoever laid out this small circular enclosure. Whether it served as a livestock pen, a garden plot, or some other domestic purpose is not recorded.
