The mound forms part of a north-south field boundary, running for some 5.5 metres along it and rising to around 0.6 metres in height. Most people walking the land would take it for a natural feature of the ground, or perhaps the remnant of some agricultural work. It is, in all likelihood, something far older.

The site has been identified as a fulacht fia, a type of prehistoric cooking site found widely across Ireland, particularly from the Bronze Age onward. The name, sometimes rendered as fulacht fiadh, roughly translates from Irish as a cooking pit or deer roast, and the sites typically consist of a horseshoe-shaped mound of fire-cracked stones accumulated beside a trough, often dug into boggy or waterlogged ground. The method, as archaeologists understand it, involved heating stones in a fire and dropping them into a water-filled trough to bring it to a boil. Fulachta fia tend to cluster in low-lying, wet ground, which makes Shanid Lower a characteristic setting. The burnt material here is thought to derive from a drain running along the eastern side of the field boundary, though no additional scorched or fire-cracked material has been identified along the drain's edges or on the surrounding ground surface. The site was compiled by Denis Power and recorded in 2011.

The site sits in agricultural land and is not formally marked or interpreted for visitors. The marshy hollow in which it lies would have been part of its appeal in prehistory, when proximity to standing water was essential to the process, but that same waterlogging makes the ground underfoot unreliable, particularly in wetter months. The visible feature is subtle: a low linear rise along a field boundary, easily overlooked without prior knowledge of what to look for. Those with a serious interest in Bronze Age landscape archaeology will find the setting instructive precisely because of how little announces itself, a faint residue of repeated activity in a place that has otherwise returned entirely to pasture.
