Rising approximately 1.3 metres high and stretching 1.5 metres wide, this weathered sentinel has long been associated with an ancient fording point across the river. The stone rests on a natural rock outcrop, and whilst local tradition holds it as a deliberate marker, archaeologists remain uncertain whether human hands ever positioned it there or if nature herself placed this convenient waymarker.

The eastern face of the stone bears intriguing markings that locals have dubbed 'cats paws', though these too may be the work of centuries of Irish weather rather than ancient craftsmen. Such ambiguity is common with Ireland's standing stones; many blur the line between natural formation and prehistoric monument, leaving us to wonder whether our ancestors simply recognised and repurposed what nature had already provided.

This particular stone was documented in the Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, as part of a comprehensive catalogue of the county's field antiquities spanning from the Mesolithic period to the 17th century. Whether placed by design or circumstance, the stone continues to mark what was once an important crossing point of the Erne, serving as a tangible link to the countless travellers who once relied on such markers to navigate Ireland's waterways safely.
