Roughly subcircular in shape, it measures about fourteen metres east to west and twelve metres north to south, rising to less than a metre at its highest point towards the south-west. Scattered across its surface are quantities of unworked limestone, and it is this combination, the regularity of the form together with the loose stone, that gives it an ambiguous quality that has not been fully resolved.

The most straightforward explanation would be that it is a spoil heap, the kind of earthen accumulation left behind when drainage channels are cut through low-lying agricultural land, a common enough feature in the Irish midlands where land management has shaped the ground for centuries. But the mound's consistent, almost deliberate shape works against that reading. Spoil heaps tend towards the irregular; this one does not. Whether it represents something older, a burial mound, a platform associated with some forgotten agricultural or industrial use, or simply a natural feature that happens to be unusually tidy, remains an open question. It was recorded and described by Olive Alcock, Kathy de hÓra, and Paul Gosling in the Archaeological Inventory of County Galway, Vol. II, published in 1999, where it was noted precisely because it sits in that uncertain space between the mundane and the potentially significant.
