Accident and Rescue Summary: 

One snowmobiler was hill climbing while his partner was watching at the bottom. As the snowmobiler was just about at the end of his highmark the avalanche fractured - it broke about 300' to his right and 200' to his left and he was unable to make it up to the ridge. He was thrown from his machine and deployed his airbag. As the avalanche came to a stop he was buried to his waist. His sled was fully buried.  

Terrain Summary: 

This was a steep 40° NE facing slope at 9800' in elevation. The Southerly winds likely added more snow to this slope as there is a large fetch zone on the other side of the ridge that is perfect for wind loading onto a NE aspect.

The avalanche stopped abruptly on a short bench where the debris piled up very deep.
