We noticed this goat-triggered avalanche on a SE slope near the summit of Lake Peak. The avalanche looked to be ~100 wide and ran for about 400'
At this entrance we lopped a Gene Simmons tongue of a cornice, sending several hundred pounds of snow to the bottom but failed to trigger a slab avalanche. Upon looking over the edge we noticed a nearly buried crown line, though it was hard to guess it's age or on which weak layer it had failed.
Ski cutting into most north-facing side of the gully, I triggered a shallow soft slab of freshly wind-deposited snow. By late morning the wind was transporting significant amounts of storm snow, though most new deposits were F to 4F hand hardness.
