Avi on nak peak

A few inches of new snow overnight. skied great and was sluffing on steeper sections 2/3rds way up nak peak. 3 skiers traversed / ski cut a slope 1 at a time with sluffing and minor cracking and stoped in safe area on slope edge. 4th rider following same tracks triggered a 30-40cm deep slab across entire slop. It ran full length into the trees ending in a giant powder cloud. Nobody was caught. Rider stayed above slide by grabbing tree. Slide just missed the first 3 below on edge of slope
