On the southern face of a low hummock in the pastureland of Skehanagh, County Galway, there sits a feature that has gone by at least two names and served at least two purposes across the span of a few decades. Marked on the 1944 to 1945 revision of the Ordnance Survey six-inch map as a hachured landform, and labelled a Gravel Pit on the larger-scale twenty-five-inch plan, it had already shifted its identity by the time anyone came to look more closely at it.

When the site was inspected in 1984, the old gravel pit was occupied by a silage pit, the kind of sunken or banked enclosure used to store fermented fodder for livestock. The extraction of gravel and the making of silage are both thoroughly practical rural activities, and here one had simply succeeded the other in the same hollow. Because the feature dates to after 1700, it falls outside the scope of formal archaeological classification, which tends to concern itself with earlier periods. That boundary means the site occupies a curious administrative limbo, documented but not quite claimed by any branch of heritage study.
