As you climb above 2000m the upper snowpack is moist in the top 40cm or more with dry snow underneath. In alpine areas, we suspect the recent snow of up to 50cm is still dry but field teams did not go into this area. Moderate to strong westerly winds are creating new windslabs in open areas. The March crust is down 50-80cm.
