It was counted, given a reference number, and then lost, its precise location within the townlands of Cloghoge and Rathcash remaining unknown. That it existed at all only came to light because a gas pipeline was being laid.

In 1983, fieldwalking carried out in advance of the Cork-Dublin gas pipeline revealed seven fulachta fiadha, the Irish term for burnt mounds, scattered across the two townlands. Fulachta fiadha are among the most common prehistoric monuments in Ireland, typically associated with Bronze Age cooking or industrial activity: animal hides, heated stones, and a water-filled trough are the usual ingredients of the theory, though their exact purpose remains debated. At Cloghoge and Rathcash, however, no visible troughs were found, which led to the monuments being reclassified more cautiously as burnt mounds rather than confirmed fulachta fiadha. What the fieldwalkers did find was the telltale surface signature of such sites: roughly circular spreads of burnt stone and charcoal showing where years of ploughing had flattened structures that once sat above the ground. Five of the seven were pinned to a map. A sixth, which fell directly within the pipeline corridor, was excavated, as recorded by O'Flaherty in 1987. The seventh was not so fortunate. No excavation, no mapped location, only a reference number marking the space where a site ought to be.
