Route & General Observations

For our Rec 1 avalanche course we toured part way up the Valley of Sin. Conditions were more prone to avalanching than we expected. So we turned around and skied on the low angle slopes at the entrance to the valley.

Red Flags
Red flags are simple visual clues that are a sign of potential avalanche danger. Please record any sign of red flags below.
Observer Comments

No signs of instability. Because of the weak and unstable nature of the snowpack we expected to hear a whumpf, but none. As we went further up the Valley of Sin, the snowpack became more variable and uncertain. Feeling in doubt, we turned around.
