An incredibly taxing line on an overhanging, south-facing wall made possible by the generous shade provided by a giant hemlock.

Begin on overhanging rock with insecure dry tool placements. Go up past the fixed gear, then angle right to the ice dribbles. Go up these to more substantial overhanging ice to the top.


First you have to find the Outback Wall. About 500' before the Wall of Excuses, go straight uphill for 20 minutes to this high, south-facing wall. You cannot see it from the trail.

The Undertainty Principle is located on the arete just left of a prominent, sheer, 90'-tall wall that overhangs 45 degrees.


There is a fixed piton and nut. After that, a couple cams, then many stubbies.
