Avalanche Details

Two small soft slabs on adjacent terrain were triggered by skiers while skinning above the side of the gully. The initial slide did not carry or bury anyone; second carried triggering skier and dog a small ways with partial burial (both easily freed themselves within seconds and no rescue was needed). Snow on this aspect was heavily wind affected; both slides were triggered in a spot where soft wind slab slid on tundra. Crown depth varied from 6-18 inches, representing the unevenly wind-deposited snow.

Events of the day

Prior to the slides, whumphing and shooting cracks were noted. Party adjusted the planned route due to these findings, but did not exit before triggering the avalanche(s).
