A cairn is situated on the summit of Mynydd Pysgodlyn at 260m above OD.
It measures 7.5m (N-S) by 5.3m and consists of small angular stones consolidated with grasses. The mound has a dished appearance, probably the result of robbing from the north side where the rim of the 'dish' is lowest. Its maximum height is about 0.4m, on the south.
A discarded OS trig point lies to the south, possibly the cause of the mound's disturbance, and what has been recorded may be the most visible remnants of a larger mound some 10m across.
