Shallow Size 1

We rode home run out. Upper third was good supportive powder. Around half way to the skin track the snow became heavier and the new snow shallower. We triggered a shallow size 1 avalanche on a tight convex roll. The crown was maybe 10 to 15cm at it's thickest and 5-10m wide. The picture is tough to see but below the skier is the runout of the avalanche.
