They are easy to miss, reduced now to grassy banks no more than forty centimetres high, with large boulders protruding at the edges and the upslope ends fading almost imperceptibly into the hill. One hut retains what may be its original entrance, a gap of about seventy centimetres near the eastern end of its northern wall, and a small rivulet was still threading through the interior when surveyors visited.

These structures are understood to have been associated with booleying, the seasonal practice of moving cattle to upland pastures in summer while families, or at least herders, followed and lived temporarily in the hills. The word booley comes from the Irish buaile, meaning a milking place or summer pasture. The huts were not permanent homes but functional shelters, built close enough to water, here the stream that divides the cluster, and positioned to make use of the rough commonage grazing above. This particular hut measures 6.3 metres east to west and 2.3 metres north to south, elongated and subrectangular in plan, its walls defined by a grassy bank of varying width between one and two metres. Five other huts of the same type survive nearby, some separated by only a few metres, suggesting this was a working landscape used repeatedly over time rather than any single moment of occupation.
