Weak Layer
Weak Layer Information
Layer Burial Date:
December 8, 2022Layer Grain Type (Primary):
FCsf - Near-Surface FacetsLayer Grain Type (Secondary):
SH -Surface HoarComments:
This layer consists of FCsf in many areas, and is accompanied by large SH in many locations. On solar aspects, this is a variably thick MFcr+FC combo. This layer formed during clear, cold weather prior to the big storm set that started on 12/8. Weather was much cloudier further north. Observations are limited there, but it appears to be less problematic thanks to clouds muting the effect of the diurnal recrystallization. During the storms from 12/8 through 12/12, many avalanches failed on this layer. Many stepped down to 11/27, others did not.
