It measures roughly 25 metres north to south and 24 metres east to west, rises to about four metres on its northern side, and carries a flat top, which is an unusual profile for a natural feature. Somebody has also dug a hole into its south-western corner in recent times, suggesting the place continues to attract curious attention, though without producing any obvious answers.

The mound is composed of earth and stone, and the leading possibility is that it may be a spoil heap, the accumulated waste material from nearby mining activity. Wicklow has a long association with mineral extraction, particularly copper and lead, and spoil heaps were simply wherever the extracted rock and earth ended up, piled as a matter of practicality rather than ceremony. That said, the mound's rounded, almost symmetrical form and its commanding position on the ridge give it an appearance closer to a burial mound or platform than to casual industrial waste. The views it commands, sweeping from the north-west around to the north-east, would have made the spot attractive for very different reasons across many different periods. Without excavation, the question of what it actually is remains genuinely open.
