Farmers extending or reinforcing their field boundaries simply built around it, leaving the stone embedded in the bank where it has stood, oriented north to south, inclining slightly southward as though leaning into the prevailing logic of the land.

The stone measures at least 1.35 metres in height, 0.5 metres wide, and 0.15 metres thick, modest dimensions that place it among the smaller end of Kerry's standing stones, though its original height before any subsidence or burial cannot be known for certain. Standing stones of this kind are prehistoric in origin, most likely dating to the Bronze Age, and were erected for purposes that remain genuinely unclear, with suggestions ranging from territorial markers to sites of ritual or astronomical significance. What makes this particular stone slightly less solitary than it first appears is its relationship to a standing stone pair located roughly 500 metres to the south-southwest. Stone pairs, two uprights set in deliberate proximity to one another, are a recognised monument type in Munster, and their alignment is often thought to carry astronomical intention, though the Boulerdah single stone's precise relationship to that nearby pair is not established. The wider Iveragh Peninsula, documented in A. O'Sullivan and J. Sheehan's archaeological survey published by Cork University Press in 1996, contains a dense concentration of prehistoric monuments, and this stone is one thread in that larger pattern.
