In reply to Ian Patterson:
You are right. I believe that originally the route did climb the little wall above the beck for completeness, though I guess its only about 8m high. And of course the 60m for the routes is a 'guesstimate'; the Cove was always quoted as being 300 feet high, in't olden days, though that might be from the beck to the highest pint of the rim - which is a bit of a cheat.
