A beautiful route that forms most years. Climb steep bumps and mushrooms to the base of the pillar. Climb the crux pillar, which will ease off after about 50 feet. The pillar is often hollow candlestick, so protection can be uninspiring. Take long screws in order to get maximum bite. Continue up to a tree belay/rappel station on the right. Many parties will rappel from here, but the route continues up easy ice for another 25-30 meters, to a tree anchor on the left.
This route is just to the right of Andromeda Weeps, and is at the far northern end of the corridor. The trail to starts where the highway makes a turn. There is a decent pullout on the right side of the highway just north of the corner. Be sure to park well off the road.
Take a good selection of screws, make sure to have some 22's for the pillar.
Belay and rappel from tree anchors.
