The mound itself is roughly eight metres across from north to south and rises about 0.8 metres above the surrounding ground, a low, irregular hump of burnt and fire-cracked stone covered in grass, unremarkable to anyone who does not know what they are looking at.

A fulacht fia is a type of Bronze Age cooking place found in considerable numbers across Ireland, typically identified by exactly this kind of mound: accumulated heaps of stone that were repeatedly heated in fire and then dropped into water-filled troughs to bring the liquid to a boil. They are almost always found close to a water source, and the site at Daingean Na Saileach is no exception, with a stream running to its east. The mound sits on a south-south-east facing slope in rough grazing land, and at the time it was recorded, the surrounding area was undergoing drainage works, which had already partially destroyed the site. That combination of agricultural improvement and infrastructure installation, the drainage trenches and the electricity pole, has left this particular example in a diminished state, though the core of the mound survives.
