Description from GGAT:
A low mound with traces of a kerb on the W side and a cist in the middle. The mound is well marked on the N side as an earthwork but less so on the other sides. It consists of a slightly raised rim and a raised centre with a more depressed area in between.

It is not possible to determine without excavation whether this is a ring cairn with internal structures, or a badly robbed ordinary cairn. The possible kerb consists of four stones (up to 0.9m across) of which the two middle ones are on the line of the outer side of the rim and therefore probably in situ; the two end stones look as though they have been displaced outwards, especially the N one. The cist is represented by a slit-like hole measuring 2.0m N-S x 0.3m, the E and W sides of which are lined by slabs; only the W side can be clearly seen, and here the lining is a single slab not quite as long as the hole.

In a clearing in forestry at the top of a hill, with a trig point on it and a radio mast immediately to its NE. A N-S path crosses the mound and has eroded slightly into it. Dimensions: Diameter 18.9m, height c0.8m max.
