While ascending the SSW ridge of Baronette - via Pebble Creek trailhead - we had 2 major collapses around 8,800' in low angle terrain. The largest collapse was roughly 50'x100' with visible cracks on the perimeter. HS on both slopes was ~120cm. S aspect. The weak layer was failing about 30cms down in facets.
Surface of the snowpack was a 2" thick melt freeze crust that supported body weight with skis on.
boot pen. - Basically the whole snowpack.
