A training film about the means of forecasting avalanches in Alta, Utah. A Ram Penetrometer being used by a ranger to observe and study the behavior of snow cover. It measures the hardness of snow. A ranger digs a pit alongside the penetrometer with a shovel. Snow temperature being recorded with the help of a dial thermometer in the dugout. Layering of snow being recorded by the ranger to detect an avalanche. About half meter long sample tubes being inserted in different layers of snow. Sample tubes being removed and weighed to determine the water content and stability. Similar tests being conducted along a fracture line. A ranger with a penetrometer at the fracture line. Snow layers being observed and recorded at the fracture line. Ram resistance and slope angles being measured and recorded at the fracture point to make a profile of the fracture line.
