The greatly mutilated remains of the grass-covered mound are now almost square due to ploughing on two sides; it now measures 33.0m across by 2.7m high. The only distinguishable feature is a small kerb-like section 0.3m high on the SE side. There is a modern cairn on the N segment. Resurveyed at 1:2500.
