An area-wide, coesive snow base is only existing in blown-in gullies and bowls and shady high-altitude slopes. That snow cover is charactized by equilibrium (isothermal) metamorphosis. It is succession of soft layers on the surfaces, partially powder snow, and faceted snow crystals with melt-freeze crusts.
