After turning around on the Boundary Glacier this morning due to waist deep post-holing through wet snow we noticed a new size 2 wet slab avalanche on Mt. Athabasca. The avalanche ran on the steep section on the ramp above the seracs. The crownline was about 50cm deep to glacier ice running over old tracks on the typical ramp ascent route.
Large depth hoar chains at the bottom of the snowpack were wet and rounding but still largely uncohesive and didn't inspire confidence.
This is a good reminder that avalanches are still happening in the alpine and to think about carrying a transceiver, shovel, and probe if venturing into steep snowy terrain.
