Mild weather continues to help settle and stabilize the snowpack. We continue to go in a good direction as far as the weak snow near the ground gaining strength and not producing avalanches. Personally, I am still using caution on steep northerly facing terrain.
Persistent Weak Layer Summary, 2021-2022:
There was a foot or more of snow that fell in October.
This snow melted away on many slopes but it stayed on northwest, north and northeast facing slopes above about 8500'.
The snow that stayed turned into a weak sugary layer during dry weather in November.
We saw a large amount of snow in December which landed on top of the weak snow from October.
The weak layer of sugary faceted snow collapsed and produced avalanches under the stress of the large storms.
The weak layer is still present. We are monitoring it and are hopeful it will become more stable with time.
