Skier reported triggering the slab on his 2nd turn, then proceeded to duck behind a large boulder for protection, realized his safe zone was not safe . He then saw the avalanche coming towards him and pointed it downhill, fortunately able to outrun the avalanche. No injuries were sustained. See obs from 12/29
The avalanche failed on a thin weak layer 3-10cm thick, sitting on a melt-freeze crust. The slab was 1F hardness sitting over a F weak layer .
Debris was 9 feet deep at the deepest location.
Stability tests today at the crown were the following:
ECTPV x 2
PST 30/100 (all tests failed on the 1mm rounding facets weak layer on the melt freeze crust bed surface)
CTM SC failed on rounding facets closer to the surface
