What was recorded in August 1984 was a rectangular outline, roughly twelve metres long and eight metres wide, made up of scattered loose boulders emerging from an eroding sand-dune face. That exposure was enough to suggest a house set within a larger rectangular enclosure, probably the boundary of an associated field. The dune itself held the ghostly evidence of human habitation: bands of dark material running through the sand, the kind of compressed organic residue that accumulates slowly in a lived-in place over years or generations.

No date has been established for the structure. The island of Fínis lies in Bertraghboy Bay, and like many small islands along this stretch of the west coast it carries traces of occupation that are difficult to assign to any particular period without excavation. The loose boulder construction and the association with a field enclosure are consistent with a range of eras, from early medieval settlement through to post-medieval small farming, but the sand has preserved the ambiguity along with everything else. When the site was revisited in April 2014, thirty years after that first record was made, the boulders and the outline had vanished entirely beneath the shifting surface. The dune had reclaimed it.
