More detailed information about the avalanche: 

Debris from a small, likely human triggered, soft slab avalanche (AS-SS-R1-D1) was observed in Voodoo Bowl.  The avalanche released near the bottom of the main north facing slope, on a convex rolleover.    Skier tracks can be seen entering the crownline from above.  The slab that released was about 100' wide and 50' long and traveled about 100' down slope.  The crownline was no more than a foot deep.  This area appears to have been wind loaded some with new snow from the weekend sitting on top of a hard crust. The skier's tracks have been filled in some by blowing snow so this avalanche probably occured sometime on Monday.
