This ancient monument, unmapped by any Ordnance Survey edition, occupies a level patch on sloping ground with commanding views southward across the Finn valley. The Blue Stack mountains dominate the southwestern skyline, whilst the surrounding bog, which has grown to about a metre in height, creates a stark contrast with the bright green grass that marks out the cairn from the darker, coarser vegetation of the moorland.

The tomb consists of a court at the south-southeast leading into what remains of a ruined gallery, all contained within a trapezoidal cairn measuring 20 metres north to south and tapering from 15.5 metres wide at its southern end to 11 metres at the north. The court’s surviving stones include entrance jambs just half a metre apart, with the western jamb standing 0.3 metres high and the eastern one reaching 0.6 metres. Several courtstones remain in place; the tallest rises to 1.4 metres in height. These courtstones appear to have been incorporated into what may be the remnants of a more recent rectangular structure, possibly a hut base, though this later addition doesn’t detract from the monument’s prehistoric character.

The gallery itself extends at least 6.5 metres in length, beginning at 1.5 metres wide at its entrance and narrowing towards the rear. The front chamber, roughly 2 metres long, is defined by single stones on each side, with a pair of longitudinally set jambs creating a segmentation between this chamber and the rest of the gallery. Beyond this point, the structure becomes more enigmatic; three additional orthostats suggest the gallery continued with at least two more chambers, though the original design might have included as many as four chambers in total. Much of the gallery remains concealed beneath cairn material, with only glimpses of the internal structure visible through holes where stones have been exposed to depths of up to 0.9 metres.
