Comments

We heli skied extensively west of White Pass today and observed the following

1) Recent wind slab/storm slab avalanche cycle to size 3 in northerly alp bowls. These avalanche were observed both in immediate lee features at ridgetop and also in steep moraine features further down slope. One stepped down to deeper weak layers.

2) One cornice collapse resulting in a slab avalanche

3) Wet loose avalanches out of steep south facing alp features

4) We also had a slope settle heavily while entering a run with a crack propagating 50m in either direction of the guides skis.

We avoided larger steeper slopes over 35 degrees and areas with the threat of fat to thin snowpack transitions.

Excellent skiing still exists in high, sheltered, northerly Alp bowls.
