Generalized cross-section of glacier facies. The snow cover is completely stripped away in the ablation facies. The entire year's accumulation is raised to the melting point and wetted in the soaked facies. In the percolation facies the annual increment of new snow is not completely wetted nor raised to the melting point, and the amount of percolation decreases with altitude, becoming negligible at the dry snow line.
Negligible melt occurs in the dry snow facies.
