I think in the end we stumbled across the Kerfland alignment – I know we asked at a farm and an old blokey told us to go left and left again, pointing roughly in the direstion we needed to go. There might have been a sign; anyway, we found them down a path off a narrow lane and they were well worth it.
Among the trees stand 3 tall menhirs about 3 or 4ms tall stand very close together, perhaps on 1 or 2ms apart. Each stone was a broad flat blade, weathered at the top and they were lined up in a row, narrow edge to narrow edge. They reminded me a lot of the stones at Stenness.
