Out at Peel Crag yesterday. Numerous (over a dozen) blocks from Hadrian's Wall have been prised loose and lobbed down the grass slope at the top of Peel Crag. As far as I could see none had made it over the edge but one was right on the lip above Overhanging crack so we shifted it out of the way. This morning I rang the National Park office who said they would inform the Park Rangers.
