It measures eight metres across and three metres deep, and unlike features produced by quarrying or deliberate infill, this concave depression appears to have been shaped directly into the existing ground, sitting six or seven metres north of a stream. Whether it was a dwelling, and from what period, remains unresolved; it carries only the provisional designation of an indeterminate-date house site.

What makes the location more compelling than the tentative label suggests is its immediate surroundings. Within fifty to one hundred and thirty metres of this hollow, there are at least five fulachta fia, the plural of fulacht fia, a type of prehistoric cooking site typically identified by a mound of fire-cracked stones left beside a water trough, usually near a stream or boggy ground. Two lie to the south-west of the hollow, and three more are scattered to the north-east. The clustering is notable. Fulachta fia are most commonly associated with the Bronze Age, and their repeated presence around this ridge suggests the area saw sustained, purposeful activity over a long period, even if the exact nature of the hollow itself cannot yet be pinned down. The proximity to running water, a practical requirement for both habitation and the fulacht fia cooking process, ties the whole grouping together in a way that feels less like coincidence than like a landscape that was once well used and well understood.
