Near and above treeline is where it's possible to find the right slab/weak layer combination to trigger a persistent slab avalanche on facets or depth on or near the ground. As we push further away from the last loading event, triggering an avalanche has become more stubborn but not impossible. Take the time to dig a quick pit before committing to a slope to see if this strong over weak snowpack structure exists. Any avalanche triggered could be large enough to injure or bury you, and most likely will take with it most of the season's snowpack.
