What makes it quietly puzzling is the apparent absence of any entrance. Most circular stone structures of this kind, however modest, are orientated to allow a person in or out. This one, as far as can be determined, shows no such opening, which leaves its original purpose genuinely open to question.

Archaeologists Quinn and Carroll, writing in 2010 as part of a heritage assessment connected to a proposed wind farm in the area, recorded the structure alongside an isolated wall nearby. The hut itself is small even by the standards of rudimentary field architecture: roughly two metres across east to west, built from uncoursed stone, meaning the stones were laid without any attempt at regular horizontal rows, and surviving now to a height of just forty centimetres. Whether it once sheltered a person, housed animals, or served some agricultural function is not stated in the record. The lack of an identifiable entrance could mean the opening has simply collapsed beyond recognition, or it could point to a structure that was never meant to be entered at all, perhaps a storage cell or a small enclosure of the kind sometimes associated with early pastoral activity in upland areas.
