Dog triggered wind slab

This wind slab avalanche was triggered by a dog south of Bozeman.  "Luckily he has good reflexes and was able to jump out of the slab as it started to move because he wasn't wearing his dogalung at the time."  While this snowpack in this photo is different from the one in the mountains, this avalanche is a good indication of the sensitivity of recently formed wind slabs.  Photo: C.
