Skiing was variable but we accomplished what we wanted in out observations and practicing up and down tracks while students took lead with guidance by instructors. We toured out the road then skinned up Coney’s. Did not see or feel signs of instability on our ski up or down but found some soft snow but mostly variable wind packed snow over previous ski tracks. One group skied main bowl and the nose of convex corner while other skied left flank of second bowl.
