Burchey, I was actually planning on using the summit hut to help with the wind. Otherwise, plenty of boulders to hide behind/under @ Iceberg.
quillansculpture, yes on June. It was actually a walk in the park due to consolidated snow and being able to glissade down which cut quite a bit of time, and stress on the knees. I'll be up the North Fork next April-June if you're interested.
