Observation Made by Brandon Brown and Cass Honebein outside of Silver Mountain Resort on the South side of Kellogg Peak

 

Snowpack Info:

  • Snow depth: 120cm to ground
  • Slope facing SSW, 202 degree heading
  • Slope angle 23 deg
  • Snow seems fairly homogenous, minus crusts or weak layers at 27cm and 38 cm and an ice crust near ground. All layers could be dented with a fist, with some slightly harder than others

ECT Test :

  • Partial collapse after 3 taps from shoulder (27cm) with no propigation, 9 taps from shoulder showed partiall propagation across half of column (38cm) 
  • Both failed on crust/weak layers 

Shovel Shear Tests:

  • Shear tests indicated it wants to slide on 38cm crust, and again at ground when the rest of the snowpack is tested below this layer. below 38cm to the rain/ice crust near the ground, the snowpack seems well bonded. 

Compression test:

  • Collapsed at 4 taps from hand at 15cm mark. Continued taps brought about failure on the aformentioned weak layers at 27cm and 38cm.
