NNE facing off East ridge of Raymond, 30-35 degrees, 8500 feet. We (unintentionally but not unexpectedly as there was already debris around from a previous skier triggered slide) triggered 2 slides - soft slab, 30cm deep, running on buried SH, they joined together to form a debris pile 100m wide and about 75m in length. My partner triggered the first near the ridge top on a slope approaching 35 degrees and I triggered the second beside, and 50 feet below, the 1st slide.
Slope angle is everything - the slope was mostly planar but the slightest rollover approaching 35 degrees was enough to tip the balance.
