Avalanche Details
Wet loose sluff was the trigger of a natural avalanche on Raven Ridge at Summit Lake sometime late Thursday or mid day Friday. It travelled to the bottom of the drainage with snow debris fairly deep in the steep drainage. Another smaller avalanche lower down was seen at 4PM on second look at the area. Tenderfoot Ridge had wide spread loose wet slides on S and SW aspects. (Picture to follow)
