- Sz 1.5 Persistant slab, toed out at bottom of track, entrained enough mass from dry loose surface to surpass a large bench and carry over. Debris was 20m wide
This ran in a reloaded spot where a distinct crown existed from a previous persistent slab avalanche, and proves this layer can be a repeat offender.
A hasty crown wall profile revealed HS of 150, 85 cm of well bonded facets from ground with a 65cm slab resting over top. The slab consisted of 25cm of 1F density Sz 2 facets with 40cm of F density Sz 1 facets resting on top.
