Snowpack

• Snowpack Description: Wind effected snow near and below treeline was surprising soft.Heavy, creamy consistency rather than hard and brittle.
  5-15 cm of wind effected snow on the surface of all exposed slopes. Easy shears on recent snow below, but there was little strength to the slab. CTE-M Q3, and ECTs just broke through the slab.
  
  Mild temps last week put a spongy crust on the old snow surface. It was very rough in the heavily trafficked areas, and nonreactive in untracked areas.
