Large whumph at 2:30pm at about 1,400 ft. just one minute after we said now is definitely the time to be off of avalanche terrain.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Sunny sunny. Calm wind. Temps in the mid 40's but felt hot in the sun.

Snow surface

Solid supportable crust at 8am that was quickly broken down on solar aspects but stayed supportable in the shade.


Solar aspects after 2pm were unsupportable.
Didn't see any new avalanches however it's really hard to see what would be new with all the numerous previous avalanche debris and we left the parking lot by 3:30pm.
