This wall is semi-shaded and can be a good summer option. The rock here lends itself to positive face climbing and most of the routes are just under vertical or overhung. There are at least a dozen quality routes here. They range from the friendly, positive Sideshow (.10c/d) and Black Flag (.10+) to the micro-edging testpieces like Soul on Ice (.12c) and the ultra-thin The Antidote (.13-). Since when were .12c and .13- "testpieces" in this day and age, you ask? Well, since you tried them at Index! There are a couple of cracks as well: the uber-classic Tree-studded House of Helene, Earwax, and Killslug.

Located on the far left side of the main upper wall. Approach via the upper wall trail. At one point the trail surmounts a step via a fixed rope. The Biology of Small Appliances (.12) arete is the first feature encountered. It should be noted that this continues to be a drop zone for trash from *ahem* "4WD motor sports enthusiasts" which consists mostly of Bud Light (TM) and Natural Ice (TM) cans but can include the occasional truck canopy or live firecracker. People have also allegedly been shot at while climbing on the Upper Walls in the past, although (luckily!) this does not seem to be a continuing issue. Use caution on the trail, particularly under the Tempitchuous area, which is a little ways before reaching Earwax wall proper.
