Location

• BC Zone: Gunnison
• Area Description: Classic Red Lady Glades Skin track from parking lot to exposed ridge before summit. We descended Skiers left of Little Lady bowl avoiding avalanche terrain.

Weather

• Weather Description: Scattered clouds throughout the morning with intermittent periods of sunlight. Around noon, cloud cover increased to overcast as SW wind speeds also increased. Precipitation intensity hovered around S-1 to S1 during our tour (ended at 1:30).

Snowpack

• Snowpack Description: At lower elevations, there was 6-10” of low density new snow. As we ascended in elevation, we found 8-17” of slab on top of various dry weak layers. Ascending on south, the slab capped a stout MfCr. As the aspect became more southeast and east, crusts become weaker and softer, unable to support the load from this storm on lee slopes. On low angle south terrain, we got a handful of collapses in gladed areas that simply don’t receive enough direct sunlight to produce a stout crust.

Avalanches

• Avalanche Description: scending the red lady skintrack, at about 11,250’, we remotely triggered a D2.5 soft slab avalanche on a windloaded E-SE facing slope NTL and below a ridgetop. The crown was 50-100cm thick, and propagated an estimated 200 ft. The slab was 4F hardness near the bottom tapering to F hard near the surface. We also noticed a dust later near the bottom of the storm snow. The bed surface was small grained (1-1.5mm facets) on top of a soft, collapsible crust. There were also small grained facets below the crust too.
