The particular stone recorded as 5E on a survey map drawn up in the 1930s has since vanished altogether, leaving not so much as a surface trace, which is itself a small illustration of how quickly even a substantial field monument can disappear from the landscape.

When the Inspector of National Monuments surveyed the area between 1934 and 1936, he counted 221 stones still standing or lying prostrate across the townlands of Timoney Hills and Cullaun, describing them as "a most remarkable group." They range from roughly 0.9 to 1.8 metres in height, all of red sandstone or conglomerate, and their arrangement appears haphazard, with the single exception of a stone circle identified in Cullaun. A later survey published in the Archaeological Survey of Ikerrin by Stout in 1984 mapped 245 stones in total, suggesting that 70 had already been removed by that point, along with five cairns, which are also now gone. The sheer density of the group, concentrated mostly in Timoney Hills with a further 48 stones spilling into Cullaun, is unusual for Ireland, but the stones' location on the landscaped estate of Timoney Park, associated with the Parker-Hutchinson family, has prompted genuine questions about whether they are prehistoric monuments at all, or whether some or all of them were placed during the estate's period of improvement and embellishment. That uncertainty has never been fully resolved, and it sits at the centre of everything puzzling about this place.
