Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Clear with scattered clouds, around 30 degrees, and no wind.

Snow surface

Around 5” of settled powder on top of a very thin crust that gave off very short shooting cracks that would go out between 3” and 9” from the source of weight/impact of my skis.


I dug one snowpit as shown. The black line indicates the weakest layer around 2’ bellow the snow surface. This layer had significantly less bonding than other layers, but in a 1’x3’ snow pillar test held very well, it should have a very low chance of releasing. The red layer is the next weakest and it held very well. The yellow layer was very strong, but could cause a point of release. The green layer was VERY thin and had a tendency to let the 4-6 inches of powder slide off the top of this layer, it is fairly bonded at the moment and should remain so for some time, but this may be a cause for concern during the next snowfall.
