Avalanche at the end of Soft Core Ridge

Postby splitboarder » January 11th, 2016, 11:09 am

Attached are some images from an avalanche at the end of Soft Core Ridge.
NE aspect (60°)
slope angle 40°
Elevation 10500'
lat/long: 35.334086, -111.659974
Total Depth of snowpack about 100cm. (fairly thin snowpack in this area. Most signs of instability were seen below 11,000)
~40cm of new snow (fist)
~40cm of older packed snow (4f)
~2cm of depth hoar *** (fist)
~0.5cm harder crust (1f to pencil)
~10-20cm of large striated basal facets, cups, chains (4f to fist)

Failed in the 2cm depth hoar(***) and slid on the thin crust. It may have initially failed at the new/old snow interface, then stepped down to the depth hoar.
Crown was about 1 to 2.5'.
Likely ran around January 7ish.
R3D2
crown <100'
length ~250'

Got an ECTX on 30° slope just above grown. So things have settled down...
There were numerous settling cracks near the crown and flank.
