A cist-cairn is located at 440m OD on a subsidiary summit to Pen Garnbugail. The mound is stony but turf-covered, 6.1m in diameter and about .4m high, with an exposed cist at the centre. The capstone, displaced, measures about 1.5m in diameter by 20cm thick. At the edge of the cairn, on its south-east quadrant, can be seen the top edge of what appears to be an outward leaning slab about 0.15m thick.
