Going off route on the Chasm Face scrabble there is a wide crack. To reach the bottom of the crack, scramble up the Chasm Face to the Catwalk and mid way along the Catwalk exit up and left 4m to a ledge and belay. Continue up and left for a further 4m to reach the bottom a 6" wide crack. It has good protection but quite difficult especially in the wet and big boots. The crack can be clearly seen on page 64 of Steve Ashtons Scrambles in Snowdonia. It's at the very top left hand side of the photo.
