AVALANCHES
In fact the term “av alanche” should be restricted to falls of snow and ice in mountainous regions. However, popular usage has extended its meaning to cover rock falls and landslips in all environments. The period of greatest danger from avalanches proper is during a thaw, when melt water makes a good lubricant for the snow and the banked steeply against rock faces, the ris-ing cloud of white dust, the vertical grooves and patches of bare rock formed by the scouring action and the dull roar of the avalanche are all common features of mountains above the permanent snow line. Rock fragments may also be carried down, for the recurrent freezing and melting ice lodged in joints and crevices of the rock forms a powerful agent of disintegration. The action is the same as that which leads to burst pipes. Freezing causes expansion of the water in the spaces of a joint and produces a pressure sufficient to break the rock.
