I was surprised to find a 10-inch thick 1-finger-hard slab sitting above the weak layer of faceted snow. I'm assuming that the slab formed during the previous days of strong winds. I did not expect that there was enough snow available to be transported but is a good reminder for me that loose faceted surface snow is still capable of being drifted efficiently enough to produce a slab, not just fresh snow. This structure might be confined to just below the leeward side of upper-elevation ridges predominantly facing east and may not exist lower down below ridges or lower elevations.
