Wasn't sure about this at the time.... however in retrospect my thoughts concur with the Canmore record:
"...amongst the stone clearance mounds of a field system is a probable cairn. It differs from its neighbours in that it is appreciably larger, 10.0m N-S by 9.0m E-W and 0.8m high, and is of regular rounded form. No cist or kerb is exposed; the mound like the adjacent clearance is completely obscured by peat...
Visited by OS (N K B) 26 April 1977."
I've also included a couple of shots of what would appear to be a small clearance cairn.
