Observation: Turnagain

Location: Magnum ridge towards head of valley from pms bowl

Route & General Observations

Yesterday I skied between some pretty big cornices on the ridge but had a nice entrance without any overhanging snow. My thought was that my line would not be exposed to cornice fall if one did occur. This was true but the slab that the cornice collapse released, some time after I left, took out pretty much all my tracks. I only post this in case anyone was wondering if this slab was skier triggered and it definitely was not even though there are three sets of tracks right at the crown. (there may be more today). Thanks .

Forecaster Comments

Photo was sent to us by a party on Corn Biscuit ridge on Sunday. This cornice likely fell naturally overnight on Saturday - taking out tracks from the previous day.
