Slab avalanche in Kokanee

Rode SW Montana trees first, snow was great, really happy with the snow, felt solid no crust. Skinned around up Kokanee ridge and rode down off the ride to lower Kokanee bowl in the open trees South facing snow felt solid. Prominent sun crust on that south face in the trees. Then skinned up the far ridge of Kokanee from the cat track, again snow felt great again. Dropped in on the north side into open trees where avalanche occurred. On the way back we noticed 2 crowns on the north face of the ridge into Montana and 1 crown at the bottom of Kokanee bowl

At the top of the trees a slight open area where a member of the party was in the middle of the slab, went for the full ride caught hold of a tree partially buried but self dug out.

Slabbed off while he was in the middle on the planar face of a open section of trees. Went for a ride but everyone ok must of slid on Jan 26th SH layer
