The top of the knoll is unusually flat, roughly twelve and a half metres across, and what appears to be a scarp, a deliberate cut or shaped earthen edge, runs around it. That scarp measures between three and a half and nearly four metres wide, and rises about one and a half metres on the western side, slightly more on the east. On the eastern side it blends smoothly into the natural slope of the knoll, but on the west there is a more pronounced step, the kind of feature that suggests human hands once shaped the ground here.

The question of whether this is a genuine archaeological enclosure or simply a natural landform that happens to be tidy at the top is one the site has not yet answered clearly. Dense gorse covers most of the knoll, making close examination difficult, and without excavation or more detailed survey it remains uncertain whether people once cut into this hillside to create a raised platform or defensible enclosure. Enclosures of this kind, which in Irish archaeology often served as farmsteads, assembly places, or sites of local significance, are common enough across Sligo, but the ambiguity here is part of what makes Farranyharpy worth noting. It sits in that category of places that are neither confirmed nor dismissed, quietly waiting on the edge of the record.
