That natural accident of geology was, at some point, turned into something more deliberate. Whoever made use of this spot gathered loose, uncut stones and built a low dry-stone wall across the open western side of the crevice, effectively closing off the gap and creating a small enclosed shelter. The wall runs about 2.6 metres north to south and reaches no more than a metre in height. The sheltered area inside measures roughly 3.5 metres along its longest axis. It is not grand, and it was never meant to be. It is the kind of structure that solves a problem, quickly and practically, using only what the landscape already provided.

The site came to light during pre-development survey work carried out by John Cronin and Associates ahead of a wind farm project in the area by ESB Wind Development Ltd. That kind of infrastructural survey, conducted under licence, regularly turns up features that would otherwise go unrecorded, scattered across upland terrain that sees little formal archaeological attention. This shelter sits approximately four metres north of a separate recorded feature, which suggests a degree of activity in this particular pocket of hillside. Whether the shelter was used by a shepherd keeping watch over livestock, by someone caught out in bad weather, or for some other purpose entirely, the notes do not say. The construction is too modest to date with any confidence, and the loose, random stonework of the wall offers few typological clues.
