The nomenclature of the various tops is very confused. Traditional guidebooks tend to rely on what the eye sees and therefore focus attention upon the five ‘crinkles’ of the summit ridge. These are generally referred to as the first to fifth crinkles, but Richards starts in the north, Birkett in the south and Wainwright employs both conventions, depending upon the direction of travel. For clarity in this article the first crinkle will be taken as the southernmost top. On this basis, the second Crinkle (also called Long Top) is the true summit of the fell. The only other Crinkle with a definitive name is Gunson Knott, but this name is used variously for the third and the fifth, with both the Ordnance Survey and the Database of British and Irish Hills listing it twice. To the north of the Crinkles proper is a depression and then the outcropping continues over Shelter Crags.
