Between two farmers’ fields is a corridor of woodland wilderness filled with the scent of wild garlic in the spring. In it is a path that leads from the road toward Barnburgh, but if you look to your right at the stone crags, every so often, hidden among the foliage is faces peering out, carved into the rock face. There are also symbols that look alien in origin, or resemble insects.

Winter is the best time to go, when the nettles and brambles no longer obscure the rocks. Otherwise it is easy to miss the carvings—some whimsical, others more serious.
