Problem
Persistent Weak Layer
Problem #1 Comments
No cracking or collapsing observed today but poor structure still exists in terrain visited.
Comments
9500' N. HS90-100cm.
Generally windy and balmy conditions observed today.
Observed wind transport even into trees that are usually sheltered.
Of note: rapid warming mid-day on high north sheltered terrain which has been previously holding cold snow.
I suspect that this warming will have consolidated the slab overlying the basal weakness.
Riding conditions have deteriorated in the terrain visited.
