WorseningBottom Line
my last trip here was notable for lack of cohesive slab above our known LOC's. (that and bushwacking on the exit).
now, I'm stepping back.
the effect of developing windslab, wind transport and weight upon known structure problems trending to worsening instability. handpits sometimes failing on isolation. 12/7 still discernable and down about 60cm @ 8800 on S aspect with propagation at mod strength scores.
as much as I'd like the PWL to get crushed, I worry we may be building to more "flush" by weeks end here.
