A fantastic multipitch ice climb if you can catch it when it's in! When we did this climb in early March 2011 it was fat and wide. You could make the climb a little easier or harder depending on the line that you choose. We climbed two full 60 meter pitches to nice(ish) belay ledges and one more short pitch to the top. Belay from trees on top.
Pick the line that looks the nicest/fattest. The flow is wide so you have some options.
To descend, walk off to climbers right on snow past Chouinard Falls.
Depends on conditions. When we did it you could place any size screw you want for the whole route. You may need a little rock pro near the top (we didn't).
