Workers found a circular mound composed of heat-shattered stones and charcoal-enriched soil, the classic signature of a burnt mound, a type of prehistoric cooking or processing site found widely across Ireland and Britain. The general interpretation of such sites is that stones were heated in fire and then plunged into a water-filled trough to bring it to the boil, perhaps for cooking, bathing, or industrial processes. By the time anyone thought to document what had been found here, the mound had already been levelled.

Adding to the puzzle, local accounts also describe the discovery of three parallel oak logs, each roughly four and a half metres in length and spaced about a metre apart, found in boggy ground some six to eight metres to the west. Whether these had any connection to the burnt mound, perhaps as part of a structure or trackway associated with it, could not be determined, and the logs themselves are no longer extant. The Owenashingaun River runs approximately sixty metres to the north, which fits the pattern for burnt mounds, which are almost always found close to a water source. Beyond that proximity, the relationship between the two discoveries remains genuinely open.
