Snow Fences
0
You will without a doubt have seen them, fences along the slopes or on the bare mountains, and have perhaps wondered what they are. They are called snow fences and have traditionally been used to prevent snow from falling on the roads and the railway. Both the high mountains and the landscape in northern Norway have sparse vegetation and therefore little protection from the wind. In the winter, the wind can get a good hold of the upper layers of snow which lie across the landscape and turn them into large slopes or piles of snow. In turn these can trigger avalanches on the slopes, but the fences are an effective protection for both people and houses. Today, snow fences are also used in alpine ski resorts, but with a different purpose. They want to keep the snow in place there so that it is not blown away, at the same time as wanting to collect drift snow along the fences.
