The last reported avalanche failing on our now mostly dormant problem child, the Persistent Weak Layer (PWL) formed during the December drought, was over a week ago on Sunday, January 12th. Good news is the snowpack has slowly gotten comfortable in its own skin. The tricky part is... while the likelihood of triggering a nasty persistent slab avalanche has gone down significantly over the past few weeks, the consequences remain severe if we do.
How do we manage the unmanageable? All the snow-pros I knows are avoiding the usual suspect slopes... steep, rocky, mid and upper elevation terrain, especially where the pack is slightly thinner. And remember... thin spots are potential trigger points and exist near bushes, rocks, or steep rollovers.
