Small sluffing on Nyack

Small sluffs were the only avalanche problem we could find today on Mt. Nyack.

• At upper elevations on Mt. Nyack, we found 4" cohesionless snow (from Thursday) on stiff windboard from previous east winds. This snow sluffed easily on slopes steeper than 40 degrees.  The snow was bonded better at mid and low elevations where it fell on softer surfaces.  We skied steep, exposed terrain using sluff management techniques.  
• No other signs of instability noted, and very minor wind effect in Cascadilla and Crystal basins. Looking north towards Rescue Creek, there was evidence of more wind effect.  
• We noted widespread small-grained surface hoar growth on shaded, upper elevations.  Southerly aspects were developing a sun crust with near surface facets above.
