The snowpack situation remains mostly the same. The snowpack is slowly adjusting to all the December snow which is quite strong. The weak snow from October near the ground has gained some strength but is still suspect. "Hand hardness" of this layer has increased a bit. Snowpit tests are stubborn but the weak layer is still shearing clean with full propagation. Below is a summary of the progression of our snowpack.
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.
