Tetons: (I) Symmetry Spire, St. John Massif. In mid-June 1947, a climber, Hans Breu, was making an attempt on one of the cliffs in this district with a companion, George Senner. Breu decided to climb a more difficult pitch than his companion felt qualified to attempt; so he went up it alone. A slip occurred, and the more ambitious climber fell 100 ft. into a tree, which probably saved his life but left him with a chipped ankle. After Senner had notified park authorities, a rescue party brought Breu down in a stretcher.

Analysis. This is another story of an unroped climber. Details are so sparse that only general conclusions can be drawn.
