That uncertainty is the most interesting thing about them. Most stone groupings in the Irish landscape, however eroded or fragmentary, can eventually be assigned to a recognised category, whether a collapsed stone circle, a burial monument, a field boundary, or the remnant of a cashel wall. This one resists that tidiness.

The arrangement was recorded by Ó Drisceoil in 1934, who counted nine stones in total and whose numbering system has been used by researchers ever since. Six of those stones are currently visible, forming a rough arc, each one low to the ground and relatively modest in scale. Stone 1, the largest, measures just over a metre in length and stands roughly 38 centimetres above the surface; others are considerably smaller, with Stone 9 barely clearing the ground at 11 centimetres. Their dimensions are consistent enough to suggest some deliberate arrangement, yet the possibility that the whole thing is a natural feature has not been ruled out. Paul Walsh, consulted on the matter, considered that a natural origin was plausible, which is not the same as confirmed, and leaves the question pleasingly open. An "anomalous stone group" is, in the language of field archaeology, a polite way of recording something that refuses to fit.
