The Aletsch Glacier is (one of many glaciers) the largest glacier in the Alps. It resulted from the accumulation and compaction of snow. Glaciers generally form where snow and ice accumulation exceeds snow and ice melt. As the snow and ice thicken it reaches a point where it begins to move due to a combination of gravity and pressure of the overlying snow and ice.The area of the Aletsch Glacier and some surrounding valleys is on the UNESCO World Heritage list, thus it is protected.
