The knife-edge.


From the wide wall to the right of the Jensen Ridge, traverse right around the nose of the Dietschy Ridge. Climb 3-4 pitches (up to 5.6) on good rock right of the crest. The 5th lead brings one back to the crest on a horizontal knife-edge. A steep yellow wall blocks further progress.
The normal route bypasses this wall on the right where steep scrambling takes one to the east ridge of Symmetry.
A more adventurous continuation after the knife-edge is to drop left into the Jensen Couloir, ascend it until an obvious line of slabs and ledges lead in a left-trending upward traverse to the crest of the Jensen Ridge at the point where the angle kicks back. From there, climb the upper 5 pitches of the Direct Jensen. (5.7)


This is the seldom-climbed ridge east of the Jensen Ridge. It's an over-looked climb on good rock that, in combination with the upper pitches of the Jensen Ridge, creates an climb that is easier than the Direct Jensen. The approach is the same as for the Jensen Ridge.
You can finish this climb by the east ridge of Symmetry Spire or the upper pitches of the Direct Jensen.
Descent is by the SW Couloir.
