Archaeology Notes
NM92NW 1 9250 2854.

(NM 9250 2854) Standing Stones (NR)
OS 1:10,000 map, (1976)

About 100 metres east of Clenamcrie farmhouse there is a four-sided monolith situated on level ground immediately south of the public road. It measures 0.7 metres by 0.6 metres at the base and is 1.45 metres in height. Close beside it, to the west, there are two large boulders, but without excavation it is impossible to tell whether or not they are associated with the standing stone.
