Recreational Observation

We dropped into a S facing aspect and skinned up a SW ridge. When we observed wind loading on the SE face of a high point at 6500ft, we opted to exit the direction we'd come up. This turned out to be a spicy move. Our ski cut triggered a hard slab (no one was caught). We exited via a low angle descent to the mellow skin track we'd already set on a S face back to the ski area boundary.
