CALAFATE...
A legend says that, Koonex, the elderly healer of a local tribe, was too exhausted and old to continue walking. Koonex, understood the natural laws of life.
The women of the tribe set up a shelter with guanaco skins and gathered plenty of firewood and food for the ancient healer and let her alone to die singing the family song.

She felt life seeping away. She began to feel the silence draw her into a heavy embrace.

Many suns and many moons pased and spring arrived, plants sprouted swallows, plovers arrived... life returns.

A flock of birds landed in Koonex shelter singing cheerfully. Suddenly, the elderly healer spoke from inside her shelter she rebuked the birds for having left her during the long and rigorous winter.

One swallow, overcoming the initial surprise, answered: - "we left in the fall because there in no food and during the winter we have no shelter".
When a sudden wind turned away the guanaco shelter, instead of Koonex there was a beautiful thorny bush of fragrant yellow flowers. During summer the ripen into a tasty deep blue berries fruit.
After tasting the fruit some birds stopped migrating and once who heard of the fruit, returned to feed.

Since then, we say, "who eats Calafate, always returns"...
