The line in the photo IS NOT Westeron Wynde. The line in the photo is the first pitch of Cabron. WW follows the dark uninviting corner to the right. The Cabron pitch is however a much nicer way to start this climb.
There is actually a crack/seam behind the yellow line in the picture. It protects relatively well with small cams and nuts. This pitch is about 10a/b if you traverse in from the right to the first bolt. There is a direct lieback flake start that is 10+.
