Beaver Ck

We observed numerous recent avalanches in Beaver Ck and the surrounding mountains. Most released on wind-loaded NW-N-E-SE facing slopes >8,800'.

Cracking in switchbacks on a SE @ 8,100'. Slope scale collapse on SE @ 8,600'.

(2/23) New/Old: 
New snow amounts ranged from 2 cm at the highway to 30 cm at 9,000'. The rain line appeared to extend to about 7,700'. New snow was well bonded on the S, SE and N aspects where we dug and we did not find any concerning facets. Snowpack tests returned ECTNs at the base of the new snow and in a mid-storm layer. 

(2/16):
This interface was the most interesting. We experienced a slope scale collapse and isolated cracking on SE-facing slopes between 8,000-8,600'. We also observed multiple small and a couple of very large avalanches on nearby SE-facing slopes. Snowpack tests on SE near the collapse returned ECTPs on 2mm FC above a MFcr ↓ 42 cm. Based on the depth, this layer was also likely involved in several of the large slides on shadier slopes. 

(2/8):
We suspect (2/8) was involved in many of the avalanches we saw today. Many avalanches started shallow, either new/old or (2/16), and then broke significantly deeper. Snowpack tests on a wind-thinned NNE @ 9,000' returned ECTP with hard force on 2mm FCsf ↓ 44 cm.
