Bishop Creek, Targeted snowpack observations. 300 degrees NW aspect, 8200’Observations
Performed several compressions tests on an avalanche course today above Forks Campground on a NW aspect, targeting our observations to the persistent slab problem. Four out of four compression tests resulted in easy to moderate failures (sudden collapse) within in a 20 cm weak layer composed of 1.5-2mm facets. This weak layer resides 80-85cm below surface and is 4 fingers-to-fist in hardness. It is below a knife-hard melt freeze crust. Evidence of rounding but overall grains in this layer are weak and not cohesive.
