There is a legend that hovers around the Rutor glacier which tells that the place now occupied by the glacier was once a large green meadow where the cows of a rich farmer grazed. One day God wanted to test his goodness and sent him a beggar to ask for some milk to feed his family. The rich farmer, instead of giving him some of his milk, mocked the beggar and, out of insult, ordered his workers to pour the buckets of fresh milk on the lawn. The beggar reacted by casting a curse on him that made it snow for days on end. Accompanying the snow was also a very cold wind which caused the green pastures to turn into ice. Thus the Rutor glacier was born.
