WebThe ablation till component is a friable, pebbly sandy loam with lenses of well-sorted sand. If ablation outpaces accumulation, mass balance is negative and a glacier shrinks.

The stones tend to be aligned with the long axes parallel to the direction of ice flow. This usually occurs at the end and sides of the glacier.

Massive amounts of water flow on the surface, within, and at the base of a glacier, even in cold areas and even when the glacier is advancing. This takes place in the ablation zone, which is the part of the glacier where the rate of ablation (removal of ice by evaporation, melting, or other processes) exceeds the rate of accumulation of new ice from snowfall.
