It is only nine metres across and two metres high, a modest cone of earth and gravel, and were it not for a small pit exposed at its summit, the precise composition of the thing would remain entirely a matter of guesswork. What lifts it out of the ordinary is not its size but its shape, specifically the pair of scarp features that step away from its eastern base like shallow terraces, curving around the mound from the north-east to the south-east in a way that seems far too deliberate to be accidental.

These berm-like terraces, narrow platforms created by the scarping of the ground at intervals of roughly two and a half metres from one another, give the mound a subtly tiered profile when seen from the east. Berms of this kind, where they appear around earthen mounds elsewhere in Ireland, are sometimes associated with burial monuments or ceremonial enclosures, though without excavation it would be reckless to say what purpose, if any, they served here. The mound itself is described as well-preserved, which in the context of earthworks in intensively farmed lowland Galway is worth noting; a great many comparable features have been ploughed flat or simply absorbed into field systems over the centuries. This one, sitting just inside the townland boundary of Cloonmore, has kept its form.
