Notes

We saw a small slab avalanche on the west side of Fisher Mountain that was triggered by a snowmobile a few days ago. The slab failed on a weak layer near the ground, in a spot where the snowpack was exceptionally thin. There was a smaller, more recent loose wet slide on the same slope about 50 feet away. Photo: GNFAC
