The first step run in a narrow gully. Overcome it and continue in the snow gully pointing to a short icicle leading to the beautifull terrace under the central step. Climb it starting slightly at the left of the center. At the end of the rope there are a couple of vague ledges crowned by thick ice bulges. Place a screw belay on one of these bulges.
Rumors say that there is a peg belay on the rocks at the left.
I have never seen it, but traversing to the left would spoil the continuity of the climb. Scramble first, and then downclimb toward the top of the central step staying on the hidrographic right. Look for a tree with slings around it. If you have found the right tree you'll land at the bottom of the step. Descend on the right, walking around the initial section of the climb.
