Obvious signs of instability
Observer Comments
Recent avalanche activity was observed on Seattle Ridge SE aspect and a recent avalanche in Basketball chute on a North aspect of Magnum near Taylor Pass.
One group experienced a large Whumph on the Magnum side of Taylor Creek at around 2000'. They suspected facets above the NYE crust due to the poor structure they found in their test pits.
