Originally included in the North of England Guide (by Stew Wilson and Ron Kenyon) based on details in October 1964 Climber magazine - because YMC did not think it was worth including in the grit guide (back in prehistoric times)
Then in YMC grit guide and second edition of North of England guide and also in North East England selective guide. New NE England guide coming out sometime soon.
As a crag it was a bit small in stature but as a bouldering venue it is brilliant - as its recent prominence has shown. It was amazing who had climbed there even before the current publicity - even saw the great John Allen there one day.
Due to the new popularity of the crag important to follow access details and park responsibly. Road up valley is narrow but look for the parking and a few hundred yards walking (if necessary) shouldn't do any harm - and will help the access situation.
