One of the best-known grade 4's of the area. Solid ice, very well protected.
Pitch 1: Climb WI 3 bulges to a stance at the bottom of a vertical pillar. Guidebook mentions pins on the left for belay. We used slings in a v-thread right of the pillar.
Pitch 2: Climb the pillar (crux, WI 4) and several ice steps that follow to the top. Rap the route.
It can also be done in a single pitch. Double 60m ropes get you down to the belay anchors at the base.
From Trans-Canada Pipeline Station drive for about 34 miles until you see the climb on the right. Leave the car on the pull off ~100 yards back, walk along the highway and climb the snow slopes to the climb.
Ice screws. Belay anchors at the base (on the left) and on top of the pillar (on the right).
