At its greatest recorded extent, the group numbered 245 stones spread across two adjoining townlands, Timoney Hills and Cullaun, with five cairns among them. By the time a systematic survey was carried out in 1934 to 1936, seventy stones had already been removed, along with all five cairns. Even the stone that prompted this particular record, logged as stone 7D on a detailed field map, could not be physically located when surveyors returned, the ground having been overtaken by furze and scrub.

The Inspector of National Monuments, writing in 1936, described what remained as "a most remarkable group", noting that the 221 surviving stones, 173 in Timoney Hills and 48 in the adjoining townland of Cullaun, showed no obvious arrangement or alignment, with the exception of one clear stone circle in Cullaun. All were of red sandstone or conglomerate, standing or having once stood between roughly 0.9 and 1.8 metres above ground. That relative uniformity of material and scale is striking, but it has not resolved the central question hanging over the site. The stones sit within the landscaped estate of Timoney Park, seat of the Parker-Hutchinson family, and that setting has led some researchers to question whether the monuments are genuinely prehistoric or whether they were arranged, augmented, or even fabricated as landscape features during the estate's development. It is a doubt that has never been fully settled.

The site is overgrown enough that individual stones are difficult to pick out, and access across private farmland is not straightforward. Those who do explore the area should expect dense vegetation rather than a clear open field of ancient uprights, and should bear in mind that what they are looking at may be something considerably stranger than a conventional prehistoric monument, a landscape whose true origins remain, for now, genuinely unresolved.
