That absence of arrangement is precisely what makes them so puzzling. When the Inspector of National Monuments surveyed the area in 1934 to 1936, he counted 221 survivors across Timoney Hills and Cullaun, and described them as "a most remarkable group". By the time Geraldine Stout mapped the complex for the Archaeological Survey of Ikerrin in 1984, the tally had reached 245 stones on paper, though 70 of those had already been removed, along with five cairns that once accompanied them.

The stones themselves are all of red sandstone or conglomerate, standing or having stood between roughly 0.9 and 1.8 metres above ground. One particular stone, catalogued as 5T and one of 46 recorded within its immediate field, measures 1.55 metres high, rectangular in section, and is orientated north to south along its long axis. With one exception, a stone circle in the Cullaun townland, the stones appear to follow no particular system of arrangement. What complicates any straightforward reading of the site is its setting within the landscaped estate of Timoney Park, associated with the Parker-Hutchinson family. That context has led some to question whether the stones are genuinely prehistoric monuments or whether their distribution owes something to the tastes of a landed estate improving its grounds. The question has not been conclusively resolved, and the stones occupy an uncertain space between antiquity and ornamental landscaping.
