Above treeline, on steep, wind-loaded slopes, especially those with with an easterly component, hardened slabs resting above faceted snow (persistent weak layer) are cracking, collapsing, and reacting to our additional weight. While the chances of waking up this avalanche dragon are decreasing, if you're getting after it on sustained, steep terrain in the alpine, remember even a small slide in consequential terrain could turn nasty if it strains us through trees, rocks, or over cliffs.
Fortunately, we can avoid this problem by seeking wind sheltered terrain out of the alpine where we're greeted with more straight-forward avalanche danger and protected, cold, recycled powder.
Earlier this week, Ted and I staged out of Smith-Moorehouse to gain access to the North Slope.... all the deets of our travels are found HERE.
