It measures 2.3 metres in length and was once upright, as standing stones, prehistoric monoliths whose original purpose remains debated, typically are. Now it lies flat on the ground, a quietly awkward fact for a monument defined entirely by its verticality.

The stone was recorded in its fallen state by Walsh in 1984, but the fall itself had already happened by the time Conlon described the site in 1916. That gap, somewhere between Conlon's original account and Walsh's later survey, is when the stone went from upright to prostrate, though the exact cause, whether weathering, agricultural activity, or simple gravity acting on an ancient foundation, is not recorded. At 2.3 metres long and roughly 0.53 by 0.25 metres in cross-section, it is a substantial slab, the kind of stone that would have required considerable effort to raise in the first place, and presumably some force or neglect to bring down.
