10 to 20 cm of low-density snow covers two prominent layers:
A facet/crust layer buried at the end of January is down roughly 30 to 50 cm.
A surface hoar/crust layer buried early to mid-February is down 15 to 20 cm.
Avalanche activity on these layers has been limited and is generally small, with releases where wind loading has buried them slightly deeper.
Below this, the mid and lower snowpack are well settled with several layers of crust
