Route & General Observations
Up standard magnum route then down the south side across the creek and up a portion of cornbiscuit. Saw lots of sugary snow on our boot pack up cornbiscuit. We continued along the ridge for a few hundred yards and then decided to drop into a gully. It was fairly steep, but we didn’t get a slope measurement.

Triggered on a ski cut. Two different slabs slid simultaneously. The bottom was ~3" thick and was above facets sitting on top of an ice or melt freeze crust. Above this there was an additional 10-12" slab. I didn't look closely at it but I'd guess wind loaded snow on top of the frost layer.
Obvious signs of instability
|Recent Avalanches?||Yes||Collapsing (Whumphing)?||No||Cracking (Shooting cracks)?||No|
We didn't notice anything until the slide.
There was a small wind lip from south to north wind above the gully.
Wind buff on top, not very soft, but not a crust.
Saw 2 separate slab and weak layer pairs. Bottom slab was ~3" deep, top ~10" deep
