Route & General Observations

On Feb. 6th a powder cloud was observed in the Surprise Bowl area of Goat mountain. My partner and I considered investigating the avalanche, but due to concerns within the snowpack and building northwesterly winds, we decided to remain out of the terrain trap drainage.
Instead, we ascended the Meadow run in hopes to get a view of the crown and flanks of the Surprise Bowl avalanche.
