The strength of the cold

When water freezes its volume increases. This property can directly affect our body, constituted mainly of water, if either part is frozen. Josep Maria Vilà, an amateur mountaineer, lost 3 teammates and his girlfriend while trying to reach the peak of Balandrau in Ripollès (Girona). The reporter Samantha Vall finds out what happened that fateful December 2000 in the Oriental Pyrenees where 10 people died. Josep Maria was the only survivor, why was saved? In Zaragoza we will know the story of another climber that saved his frozen toes thanks to the care provided in the mountains. But appart of being harmful, sometimes the ice is beneficial. Acts as an insulator layer on the frozen lakes and allows the existance of liquid water below, and therefore the persistence of life. To check this, the reporter Pere Renom dives into a frozen lake at Panticosa (Huesca).
