Snow surface

In the Alpine the riding was difficult on the leeward side (WSW aspect) with 2"-6" of wind stiffened surface snow above soft low density snow.
Below 2000' in the trees the top 2' of snow was right-side up.

While setting the up-track we encountered a few small pockets of wind slab on the Sunburst ridge - nothing more than 6" thick. It mostly crumbled beneath skis, but we had a couple spots where it cracked further ahead 5'. These wind slabs were sitting atop soft unconsolidated snow.
