Much of the trail from Alta Central to Cardiff Pass was totally obscured at 415 PM, despite knowing that a few people had been up within an hour of me. On the test slope/pole line hill, I found drifts up to two feet deep. Up at the pass, I was able to follow a broken trail to the pass itself, and on the ridge it was easy to trigger small soft slabs on the cornices above the pass. These soft slabs were about 5 inches deep and 10 feet wide, with some much deeper drifts around that didn't quite seem reactive yet. I would expect these wind slabs are big enough on the right terrain features to catch and carry a person, and that they'll grow bigger overnight if the winds remain strong. I'd also expect wind slabs to be big enough to tip the scales on shady slopes with thin, weak snow, such as repeater slide paths in the monitors, rocky point, and upper days.

See above.
