Mount Smuts looking down the groove on Step # 1. Best viewed at original size.

Note lower steps A and B. and the ridge crest.

As you come up the ledges from the scree gully you will come out just above Lower step B. If you plan to climb the groove you should cross the ridge crest at that point. You cannot cross over once you move up the crest.
