Wind-affected snow surfaces on upper elevation north-facing slopes.

The thickness of the windboard varies across exposed slopes: punchy skinning and challenging skiing.

Southwest, south, and southeast-facing slopes up to nearly 8500 feet are nearly snow-free.

Instability Comment
<p>On my exit, late in the afternoon, I was able to trigger 2 slow-moving, size 1, wet loose avalanches in the isothermic snow on mid elevation east facing slopes.</p> <p>Old natural wet loose avalanche near the Deer Creek saddle.</p>

Strong north winds created a pencil-hard wind board above 8,500 feet, extending even into the trees. This crust may lead to a dangerous, counter-intuitive setup with future storms: wind-hardened upper slopes may actually support new snow better than mid-elevation protected terrain. Travel in typically 'safe,' sheltered 'lower' elevations may be more dangerous due to the weaker underlying snow surface.

Easy to intiate small loose dry avalanches on steep, sheltered, mid-elevation, north-facing slopes.
