The pit, just fifteen centimetres deep and twenty centimetres wide, was sealed with a single stone slab roughly sixty centimetres long. What was found inside amounted to only small quantities of cremated bone, mixed through with soil, the modest physical trace of what was once a deliberate and presumably meaningful act of burial.

The find was documented by Shee-Twohig and Doody in 1989, and the burial is thought to be prehistoric in character. Pit burials containing cremated remains are associated with Bronze Age funerary practice in Ireland, a period when cremation was widespread and the dead were often interred in modest, unlined pits or in ceramic vessels placed in the ground. What makes Killountain particularly notable is its immediate context: a standing stone sits adjacent to the burial. Standing stones, large upright slabs set into the earth, are common across the Irish landscape and are frequently, though not always, associated with burial activity or territorial marking. The proximity of this stone to such a small and contained cremation deposit suggests the two features may have been related, one perhaps marking or commemorating the other, though the precise relationship remains a matter of interpretation rather than certainty.
