Ascent of Alter Weg as trad by Christoph Rauch

The original line starts in the middle of the face in easy but grassy rock, then goes to the crack on the right. From the last ledge, it traverses left into the vague dihedral, then further diagonally up to the left. The dihedral is certainly the hardest part, but I don't think it's 6- as it's given in most guidebooks.
