Skiing/SnowboardingLocation:
Top of first step in Giant Steps CouloirObservations
Steps were heavily wind eroded. Very steep old hard slab wind loaded roll over at top of first step. Stable. Triggered a small soft slab at the top of the first step. Second step top 50 ft was 3D sastrugi. First two steps had decent, relatively soft windboard with little sun effect. Third step started the same and transitioned to some wet windboard. Once below 10000 ft we saw massive wet slides on all aspects, looked to be potentially less than a week old.
