This ancient stone chamber, revealed by erosion along the northern edge of a 2.5-metre-wide pathway through the marram grass, offers a rare glimpse into Bronze Age burial practices along Ireland's Atlantic coast. The trackway itself winds between granite outcrops to the north and stretches of golden sand that lead 50 metres south to the sheltered waters of Gweedore Bay.

The visible portion of the cist measures roughly 0.75 metres east to west and extends at least 0.7 metres into the dune face. Its construction is elegantly simple; a substantial granite capstone, measuring about 1.2 metres in length, rests atop thin side stones that have tilted outward over the millennia. These supporting stones, originally vertical, now stand 0.46 metres apart at their base and widen to 0.75 metres at the top, creating a trapezoidal cavity partially filled with sand. A third side stone can be glimpsed within the eastern edge of the chamber, whilst the interior extends northward into darkness beneath the protective capstone.

The surrounding stratigraphy hints at a more complex burial monument than what remains visible today. A jumbled layer of stones extends approximately 1.2 metres east of the cist at capstone level, possibly representing the remnants of a covering cairn or associated pit feature. Additional stones scattered through the sand layer west of the chamber suggest this burial was once part of a larger funerary landscape, now largely reclaimed by the shifting coastal dunes. The cist's precarious position, half-swallowed by sand and exposed by a modern track, serves as both a window into prehistoric ritual and a reminder of how fragile these ancient monuments remain in Ireland's dynamic coastal environments.
