Though the odds are decreasing, it is still possible to trigger a deep and dangerous avalanche failing on a persistent weak layer of loose, sugary facets that formed in February. Significant snowfall and strong winds have built slabs 2'-4' deep over top of this weak snow. You are most likely to trigger an avalanche involving this persistent weak layer on steep, wind loaded, north through easterly facing slopes right around treeline, or in shallower, rocky areas in the alpine. Avoid likely trigger points such as steep convexities or thinner snowpack areas around rock outcroppings.
