No account of its removal survives. No local tradition appears to have recorded it. What remains is a single cartographic clue: the word 'Cromlech' marked on the original Ordnance Survey six-inch map, a term applied by nineteenth-century surveyors to what we would now generally recognise as a megalithic tomb, typically a chamber of upright stones capped by a large flat slab.

The monument at Reisk was noted by Ruairí de Valera and Seán Ó Nualláin in their 1982 survey of megalithic tombs, where it appears as a lost site rather than a recorded one. By the time the OS Name Book entry was compiled in 1904, the structure had already been gone for at least two decades, and the compilers could add nothing beyond the map label. Whether it was dismantled for building stone, subsumed into field boundaries, or simply cleared from agricultural ground is unknown. The wet terrain near Knocknabansha may have offered some protection from intensive farming over the centuries, but clearly not indefinitely.
