Before 1936, a large circular cairn, a mounded heap of stones raised over the dead, rose to roughly seven metres in height and measured around forty metres across. It was a substantial presence on that ridge. Then it was quarried away for road material, and the site was effectively erased.

The destruction brought an accidental discovery. Workers uncovered a stone cist at the cairn's centre, near its base. A cist is a small box-like burial chamber built from flat slabs, and this one, measuring just under two metres in length and barely more than half a metre high, was roofed with a single capstone and floored with another slab. Inside, in a badly disturbed condition, were the bones of three individuals. The account was published by Hynes in 1937, and the site was later noted by the archaeologist John Waddell in studies of Irish burial cairns from 1975 and 1990. An earthwork of some kind lay roughly thirty metres to the south-east, suggesting this was once a more complex ritual or funerary landscape. Nothing of the cairn survives above ground today.
