Comments

While skinning into the wind loaded alpine, we started to remote trigger small avalanches on wind loaded slopes. While skiing a low 27 degree slope, ski cut started a .5- 1 avalanche. The biggest slide we saw could be a size 1.5 at tree line below a cornice which had a crown thickness of about 30 centimeters and ran down the slope about 30 meters.
