A survey conducted between 1934 and 1936 by the Inspector of National Monuments counted 221 stones across two neighbouring townlands, Timoney Hills and Cullaun, and even that figure represented a reduced population. An earlier map published in the Archaeological Survey of Ikerrin recorded 245 stones in total, of which 70 had already been removed, along with five cairns that have since disappeared entirely. The stone documented here, marked as 4L on the 1936 survey map, stands 1.63 metres high, is roughly square in section, and shows no evidence of packing stones around its base, the small rocks typically used to stabilise a megalith when it was first erected.

The 1936 inspector described the group as "a most remarkable" collection, noting that the stones, all of red sandstone or conglomerate, stood between roughly 0.9 and 1.8 metres above ground and appeared to follow no particular arrangement, save for one stone circle identified in the adjoining townland of Cullaun. That absence of a discernible pattern is itself worth pausing over. Most prehistoric monument groups, whether stone rows, circles, or alignments, carry some internal logic, however obscured by time. Here, the stones seem simply to proliferate. There is, however, a complicating factor: the entire site sits within the landscaped estate of Timoney Park, the property of the Parker-Hutchinson family, and that setting has led some researchers to question whether these monuments are genuinely ancient or whether some or all of them were arranged, or added to, as ornamental features during the improvement of the estate grounds. The question has not been definitively resolved.
