The larger of the two is a standing stone, 1.49 metres high and 1.27 metres wide, oriented roughly northeast to southwest. On its southeast face are two possible cup-marks, shallow circular depressions worked into the stone surface that appear on prehistoric monuments across Ireland and Britain, though their precise meaning remains debated. A packing stone, used to stabilise the upright when it was first erected, is still visible at its southwest side.

The second structure, only four metres away, is harder to read. It measures approximately 2.3 metres north to south and 1.4 metres east to west, and is defined by several upright slabs of unequal height, one of which tilts markedly to the southwest. At the southern end, partly swallowed by the ground, lies what may be either a capstone or a displaced orthostat, that is, one of the large upright stones that would have formed the walls of a megalithic tomb. Beyond the northwest end, another slab lies prostrate and is largely buried. Archaeologist J. Cuppage, writing in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, noted that the structure cannot be classified from surface examination alone, though it may represent some form of grave. The precise relationship between the standing stone and this ambiguous structure remains unresolved.

What makes the site quietly compelling is precisely this refusal to yield a clean interpretation. The cup-marks on the standing stone are described as doubtful, the nearby structure could be funerary or something else entirely, and a buried slab at the northwest end hints that more of the site lies hidden below ground. An Gleann Mór itself is a wide, open valley, and this small cluster of ancient stones on its slopes sits without fanfare, categorised but not fully understood.
