Avalanche

Remotely triggered from about 125' away. Slide was about 50' wide, ran approximately 150'. Crown size ranged from 1- 3 1/2'. Observed two other sympathetic slides. One of which was above original slide, unsure of distance run, but crown height appeared to be > 4'. Second observed slide was smaller in size, roughly 20' wide with a 1-2' crown height. All of the above mentioned slides were all in wind loaded areas. Western side of northerly aspect. SS-ASr-R2-D2-O
