First and foremost, this observation is decidated to the out-of-staters whose car flew past us just inside the park gate and then promptly ran a stopsign and went off the road. We'd love to know what had them in such a huge hurry to get to Apgar (late for a snowshoe tour, perhaps?).
We headed into the boosh moat surrounding the Apgars keen to avoid wind-complicated snow. Skies were either partially cloudy or the giant orb showed through, and temperatures were certainly below freezing everywhere except our thermoses. There was very light wind on ridgetops, but no place else.
The surface wind-slabs noted by other parties were primarily within 300-500 vertical feet of the ridge crest, and moreso on S aspects as we dropped in elevation. Our pit at 5680ft on an East aspect and 35ish degree slope (total snow depth 180cm) surprised us with a propogating results 55cm down (ECTP22). The propogating failure occured in preserved stellars on a density change (4F above and 1F below). This surprise noted, we dialed back to skiing slopes less than 35 degrees and with increased travel precautions (skiing one at a time with good visibility from safe areas) in areas where slabbiness was afoot.
