Observation Rock/North Face

Snow section was hard and icy. Used pickets during the lower four pitches, in part during the climb but also as anchors. Most of the pickets were bomber. Towards the end of the 4th pitch and during the 5th pitch snow/ice was too hard for pickets but took screws really well. Used quite reasonable screws on all pitches. Top ice section in great shape, took screws well. Climbing teams led all pitches (didn't simul-climb). Left TH at 7:00 AM, returned to cars at 8:30.
