Manning park east ridge

Viewed very recent size 1 avalanche on south facing slopes ( happened within the hour approx) on the east ridge outside Apple bowl at manning park ski area. Approx 25 foot crown and 45cm wind slab on a convex entrance to gully/ terrain trap (skiers right). Appeared to be skier triggered as there were two sets of tracks in the hang fire. Did a quick beacon scan, no signal detected. No sign of burial.
