On a glacier, the accumulation zone is the area above the firn line, where snowfall accumulates and exceeds the losses from ablation, (melting, evaporation, and sublimation). The annual Glacier equilibrium line separates the accumulation and ablation zone annually. The accumulation zone is also defined as the part of a glacier’s surface, usually at higher elevations, on which there is net accumulation of snow, which subsequently turns into firn and then glacier ice. Part of the glacier where snow builds up and turns to ice moves outward from there.
Famous quotes containing the words accumulation and/or zone:
““Under an accumulation of staggerers, no man can be considered a free agent. No man knocks himself down; if his destiny knocks him down, his destiny must pick him up again.””
—Charles Dickens (1812–1870)
“In the zone of perdition where my youth went as if to complete its education, one would have said that the portents of an imminent collapse of the whole edifice of civilization had made an appointment.”
—Guy Debord (b. 1931)
