Roughly D-shaped, around twenty metres long and ten metres wide, and no more than two or three metres deep at its lowest point, it sits with its straight northern edge pressed against a road, its floor covered in stones of assorted sizes that are thought to have been cleared from surrounding fields at some point in its history.

The confusion around what this feature actually is has a paper trail of its own. By the time the Ordnance Survey produced its 25-inch map in 1893, the site was already described as a disused gravel pit. Yet the 1916 six-inch map shows only a small semi-circle of hachures, the cartographic shorthand for a scooped or hollowed landform, giving no indication of its former use. When the site was formally catalogued in 1992 and again in 1996, it was entered under the category of earthwork, a broad classification used when the original function of a man-made ground feature is uncertain or ambiguous. In this case, the earlier Ordnance Survey label of gravel pit is probably closer to the truth. Small quarries of this kind were once commonplace in rural Ireland, dug to extract gravel or stone for road repairs and farm tracks, then abandoned once the useful material was exhausted or the need passed.
