Avalanche Details
Spoke with a party in Tin Can parking lot who triggered a D1.5 soft slab avalanche in Tin Can Common bowl. He noticed the slope cracking up below him and angled off the slab while descending. This released as a pocket, mid-slope (see photo) and appears to be comprised of yesterday's storm slab/ wind slab.
**Avalanche dimensions are approximate.**

Snowboarder-triggered (D1.5) avalanche on SW face of Tin Can Common bowl. This appears to be comprised of todays storm snow/ shallow wind slab.
CFR looking 'wind-textured' from moderate to strong easterly winds today. Notice the anti-tracks in the middle of the image.
