Comments

Widespread natural and several reported remote triggered avalanches occurred during yesterday's storm near Tony Grove Lake.

We observed natural soft slab activity on steep slopes at all elevations. The wind and storm slabs were 1 to 1.5' deep and 20 to 500' wide.  Avalanches failed on sugary faceted snow (near surface facets).
