Y'areet there Rockandy,

Apparently a lot of the older wooden cross sockets (manifesting as nowt more than rectangular holes in otherwise undressed stone) were along a pilgrimage route associated with Cuthbert. There's one that gave me gyp in North Tyneside.

There must be a fair chance the Chatton area would have been on the route of the Cuthbert trail, especially given the relative proximity to Cuddy's Crags.

It's a wonderfully inscrutable looking stone.

PS: Nice Hunterheughing :)
