avalanche on round top

Active wind slab problem.  It looked like the wind slabs were recently formed from the Wednesday night wind event. Naturally triggered wind slabs and debri observed. Crown lines lining the summits on near by peaks. Naturally released wind slabs on steep deposit zones mid and lower in the bowl.  Crown lines varied from 6 inches to 18 inches. 

4F hard wind slabs, on top of F layer 10cm, with 4F hard layer below.

1mm facets / 2mm needles in 10cm Fist hard layer below wind slabs. 

#1 = CT 0 Sudden Plainer collapse on isolation @ 44 cm down from surface

#2 = CT 1 Sudden Plainer collapse @ 60 cm down

#3 = ECTP Sudden Plainer collapse on isolation @ 60 cm down 

#4 = ECTP 1 SP ( non formal block) full propagation @ 60 cm down from surface. 

Two layers of wind slabs, both showed reactive results.

Spooky day.

Multiple other wind slabs found and relased (5+). Many natural debri feilds observed. Rapid wind loading from strong south winds. Turblent suspsension near ridge tops and consistent blowing snow in the bowls.
