A film depicts the causes of avalanches. Mountainous region in the United States. Snow covered mountains. Shows and explains how wind causes dangerous cornices. The blowing of heavy wind continuously in the same direction can cause avalanches. A diagram shows the procedure. The occurrence of avalanches can be predicted with the help of several devices. A man holding a tube known as snow sampler. He prepares the tube for the purpose of prediction of avalanches. Men working in the test area. A spanner wrench is placed in the snow. The tube is placed on the wrench to predict the avalanche. Men digging up trench in the snow to inspect the layers of the snow. They measure the thickness of the layers. The observations are recorded. A chart depicts the observations.
