Kernpunkte

Be cautious near areas of wind-affected snow in exposed terrain. Very steep slopes where you find wind-drifted, pillowed snow or areas below cornices are in the bullseye of existing avalanche problems. The possibility also remains of triggering a much larger avalanche on weaker snow buried in the snowpack.

    Slabs overlying weak layers buried 2-3 feet deep remain possible to trigger on very steep slopes over 35°. Signs of instability such as cracking, collapsing, or recent avalanches may not be present before triggering a large, dangerous avalanche capable of propagating far across or upslope. Multiple tracks on a slope do not indicate that a slope is stable. Stick to lower consequence terrain away from terrain traps and rocky, convex, very steep slopes today.

    This terrain is very steep and cliffy and has produced multiple avalanches in the past 10 days. This is a prime example of a slope harboring persistent weak snow.

    2–3

    Weak snow buried 5 feet deep exists near the ground above 9,000’. Triggering an avalanche at this depth is very unlikely but not impossible.

    On February 10th, a rider stepped off their sled and triggered a very large avalanche that failed near the ground on Lava Mountain. This avalanche was triggered where the overlying slab was thin making it possible for the rider to impact the underlying weak layer. Manage this problem the same way you would manage weak layers in the middle of the snowpack by avoiding very steep, rocky, and wind loaded terrain.
