When surveyors revisited the six-inch OS map of Srah in County Galway during the 1948 revision, they recorded one such feature near the edge of a bogland. It looked, on paper, as though it might be something worth noting. When someone finally went to look in 1983, the ground told a quieter story: a hollow in the pasture, almost certainly the remains of a sand or gravel pit, dug at some point after 1700 and long since abandoned to the grass and the nearby bog.
