In reply to sjc:
I something like this in the Spring, although we descended to Cam Crags, we weren't aware of the ridge so just came down a gully. It may add several extra miles, but they are for the most part in Langstrath, so that's no bad thing. Was dry when we did it, but I wouldn't have though Corvus would be much harder in the wet. There were a lot of new fences about up there, but the way was pretty well trod and I think there were styles from memory. Good day out we thought.
