A feature marked on the 1946 revision of the Ordnance Survey six-inch map drew enough attention to prompt an inspection in 1985, at which point investigators found not an earthwork or ancient enclosure but a quarry, already filled in and absorbed back into the improved farmland around it. The hachured symbol on the map, a cartographic shorthand for a depression or raised feature, had preserved the memory of something the ground itself had long since swallowed.

The quarry dates to after 1700, which places it firmly in the era of agricultural intensification and estate improvement that reshaped much of the west of Ireland over the eighteenth and nineteenth centuries. Small quarries of this kind were commonplace across rural Connacht, opened to extract stone for field walls, farm buildings, or lime kilns, and often backfilled once the immediate need had passed or the land was consolidated. What is quietly striking about this one is how it survived at all, even as a cartographic ghost. The 1946 map revision caught it; the 1985 inspection confirmed its erasure. Between those two dates lies the whole arc of a feature's life in the landscape record, noticed, queried, and finally closed off.
