Hachures, the short radiating lines cartographers use to suggest a depression or raised earthwork, marked both as something worth recording. When someone finally went to look in 1985, one of the features turned out to be a disused quarry. The other had vanished entirely from the landscape, leaving no visible surface trace whatsoever.

What makes this quietly interesting is not what was found but what was not. The map suggested two quarries; the ground confirmed one and erased the other. Stone quarrying at this scale was commonplace in rural Ireland, typically small, localised operations supplying material for field walls, road repairs, or nearby buildings, and they were often worked out and abandoned within a generation. Without continued use or maintenance, a shallow quarry face can slump, fill with vegetation, and disappear surprisingly quickly. In this case, the cartographic record from 1948 is the only surviving evidence that a second extraction site ever existed in this part of south Galway. The map outlasted the place it described.
