The first edition of the Ordnance Survey six-inch map, produced in the mid-nineteenth century, recorded it as a sand pit, the kind of working extraction point that would have supplied local building and drainage needs. By the time the more detailed twenty-five-inch OS plan was drawn up, the same feature had become a gravel pit, and a disused one at that, suggesting the extraction had already wound down before the surveyors arrived with their second set of instruments.

The change in label between the two surveys is a small but telling detail. Sand pits and gravel pits served overlapping but distinct purposes in rural Ireland: sand was prized for mortar and plaster, gravel for road metalling and land drainage. Whether the material extracted here changed over time, or whether the two surveying teams simply assessed it differently, is not recorded. What is clear is that the feature dates from after 1700, placing it within the era of improving landlordism, road-building schemes, and the broader transformation of the Irish rural landscape that accelerated through the eighteenth and nineteenth centuries. Rafarn itself is a small townland, and a working pit of this kind would have been an unremarkable but necessary part of local infrastructure for however long it remained active.
