Snowpack Summary

Strong SW wind and warm temps have likely created windslabs in the alpine. The October 25 crust, sitting 0-40cm off the ground, remains a concern. This crust is most prevalent in deeper snowpack areas - found predominately on N-NE lee features. Faceting above and below this layer continues to weaken the lower snowpack.
