Comments
See Video of Avalanche Below. This Avalanche was remotely triggered by a snowmobiler climbing on the adjacent slope. Snowmobiler felt the snow collapse and shooting cracks propogated to the adjacent hill and caused the avalanche to release at the ground level.
Comments
A separate avalanche was unintentionally triggered by a snowmobiler. This avalanche triggered into the old facet snow layer from the January Cold spell. This was in relatively the same area, but was a little larger.
