The site is classified as anomalous, a label that signals something genuinely puzzling: the stones do not conform neatly to any recognised monument type, neither a formal stone circle nor a simple pair nor a row, and their original purpose remains unclear.

The group was documented in some detail before it disappeared from view. A plan drawn up by University College Cork in 1912 recorded three stones set at the points of a triangle, with stones A and B standing upright and stone C already lying flat and partially embedded in the ground. Condon, writing in 1916, noted the dimensions carefully: stone A was just over two metres tall and the most substantial of the three, stone B considerably smaller at 1.2 metres, and stone C a low flat slab measuring roughly 1.2 by 1.4 metres. The spacing between them was modest, with A and B just under two and a half metres apart, and B and C a little over two metres. By 1938, when the six-inch Ordnance Survey map was compiled, the site was marked with the Irish term galláin, meaning standing stones, though only two stones were indicated at that point. At some stage after that, the above-ground trace vanished entirely, leaving the pasture unmarked.
