Comments
We observed this avalanche that most likely occurred within the last few days. This was a natural avalanche that appeared to have started as wet-loose rollerballs and stepped down to create a wet slab avalanche on a southeast facing aspect of the gully. The slide was approximately. 100-150' wide and ran 1200' vertical. Probing in the bed surface there was still 170-190cm of snow left below the debris. This wet slab avalanche gouged out a significant chunk of the upper level snowpack and pulled to the ground in steep cliffy areas. It did not run full path and started approximately halfway down the slide path.
