The snowpack still has a poor structure and has proven it can produce large and destructive human-triggered avalanches. While the likelihood of triggering one is decreasing, the consequences remain high. Any avalanche failing on this persistent weak layer would likely break to the ground, taking out the entire season’s snowpack, and could result in a season-ending injury—or worse. This is a classic persistent weak layer problem. It’s not going away on its own, and it will take a substantial amount of new snow to ever put it to bed.
The base of the snowpack continues to weaken, consisting of large-grained facets and depth hoar. The primary weak layer of concern sits just below the Christmas rain crust. In some areas, this crust may feel supportive under your skis or board, but its ability to bridge the weak snow below is highly variable and unreliable. Don’t let a lack of obvious red flags lull you into a false sense of security.
If you’re traveling in avalanche terrain, start with small, low-consequence features. Avoid steep convexities, terrain traps, thin rocky areas, and slab margins. The most effective way to manage this problem is to avoid it entirely by sticking to slopes less than 30 degrees
