Wind! Past black knob it was probably a consistent 20 mph with higher gusts, anything N facing was touchy above 10,000'. I went out a foot too far from the skin track and trigger a wind slab on a rollover which ran about 500'. This will undoubtedly be a problem of growing concern the next few days. otherwise S facing felt pretty stable, a couple of hand pits showed right side up snow w/ no obvious layers.
